Title: Tv forums
Post by: cam.in.head on 21 February 2021, 14:58:37
Hi all.
As well as my car interests I have always had an interest /hobby in vintage hifi and tv and most recently progressed into plasma tv's.
What I was wondering is has anyone any reccommendations as to a good online forum similar to ours but for my hobby.
Heard of badcaps and a few others but just thought you may know of any I've not .something uk preferably and catering from valve tv's up to plasma ( hi-fi too)
Any ideas

AV Forums immediately sprung to mind, but that does tend to be people showing off latest and greatest.

plasma TVs use a shed load of electric too £££££  :o
If you do some calculations based on power usage and cost and how long each day your TV is on ...
you can justifiably soon talk yourself into a newer TV  :P
but you'd probably have to turn on the central heating to replace the heat that the plasma used to give  :D

hi kevin. is that your own website then ?  interesting stuff.
i know i enquired a couple of years back and i think it was you who replied regarding issues i was having with a x50 panasonic plasma power supply. some of your answer made sense ,some didnt but that was early days for me with plasmas ( and smps) for that matter. i have learnt a bit since then.
i am a servo motor and panel designer/ builder by trade so a lot of my work stuff isnt realy relevant to electronics as such.but its something im interested in so it will go into my brain !.
i will browse some of the suggested sites and see what looks good or usefull/ interesting to me.i am always up for learning new methods and obviously youtube is ideal for seeing other peoples methods and repairs.although theres lots about tracing faults down to actual whole panels but its abit more interesting and self satisfying to go in at component level. not 100% successfull at that yet but have repaired a few panasonic sc boards and also samsung power supplies with the faulty caps.  cheers,thanks for replies

I used to have one (46"), since it went the money on the electric saving has paid for the replacement (55") and the fund is still growing for a 65" and covered the icreases in the lecy bills

samsung power supplies with the faulty caps.
As its a very well known problem, it doesn't really need any diagnosing, so I tend not to bother on those.

Despite being a qualified TV repair person* - albeit it in the old analogue days - I knew I'd never make money off it, and only every did as a bit of a hobby.  I enjoy diagnosing that sort of thing.  But the tedium of getting the iron out and replacing capacitors on something that doesn't need any diagnosis means I simply CBA ;D

around here there are a few tv repair shops and theyre always packed out so theres money still to be made ,after all new ones aint cheap so a repair is worthwhile .i would imagine its mainly led backlighting faults nowadays.
im not particularly bothered about 4k as i dont have 4k eyes ! so as plasma is vastly superior to lcd thats what i favour nowadays.
although my main living room tv is still a 36" panasonic crt and is hard to fault picture and especially sound wise.
lets not start a debate thou !  each to there own .

They are throwaway items now.  Minimal heat generation from the recent LED backlit LCDs helps with reliability, and most are 2 PCB surface mount, so tends to be board swapping for many workshops.  With even branded 40" LCDs costing less than £300, people aren't willing to pay £150 to repair their shitty old ones. well, not enough of them to make money off it.  Plus I got my certifications back when the G11 chassis was all the rage ;D


LCD technology panels far surpassed Plasma and other phosphorous technologies years ago.  The niche look-at-me's could potentially argue that only pretty recently did LCD blacks match plasmas, but a) they are wrong in all everyday conditions, b) far more to picture quality tan blacks.

local shop here says 95% of all faulty tvs now are led backlights and cannot remember ever having to change any flourescent backlights of pre led ones.says they are usually overdriven and can fail very quickly especially if backlight setting is high.hes mown out with repairs and opens 7 days so hes ok !
my partner  has a superb 65" panasonic 700 series that we bought and repaired which runs at about 750 watts. certainly gives off some heat but picture is excellent and sound quality is out of this world.she loves it.
a few years back i had a ferguson colourmaster 24" ? i think ,(ex der rental set)that certainly gave off some heat  and was a complicated beast to keep going.
excluding the very new 4k led screens ive yet to see any lcd set that looks good.even when set up properly they never look real to me .partly my eyes,partly my refusal to modernise ! but it doesnt realy matter does it,we all like what we like .

It'll be shagged in a few weeks. Plasmas degrade from the moment the are used, and after around 1000 hours its very visible.  Even on Panasonic, who arguable made some of the best plasmas (because they hung on to the bitter death, being unable to make a decent LCD.


As to LCD reliability, the inverters for the older ccf tubes used to retune to channel smoke, and the ccf's themselves had a limited life. Not seen or heard of many LED backlights go, and certainly not worth repairing unless its something special.  Maybe sweatshop labour is more affordable up north?  Round here, anyone who can use a heat station competently is gonna want more than £20 an hour, even at sweatshop rates, and do-gooders insist on the right 'ealth and safety.  So I'd be wanting around £200 for a 45 minute repair, which nobody in their right mind would stump up for.  More if they wanted collection/delivery.

as said earlier its all personal taste. i like mending stuff regardless and more so if its your hobby. similar to the car scene realy.if i wanted modern souless crap id buy a kia or hyundai but as with many others on here i prefer older and debatably better stuff.this works for me in my life and relates to most things.tv,s,hi-fi,cars,houses,even people ! especially women. no way in a million years would i want to be 21 again and have that kind of lifestyle that people that age seem to want nowadays.all fake. no way hose !
you have only to look at some older music videos on youtube to realy appreciate just how bad things are nowadays. look up magic from 1987 by olivia newton john. seriously.she was absolutely stunning,never realy noticed before.no tatts or piercings.no arse or boobs hanging out and sings like an angel with no computer autotune. no-one comes close nowadays. im glad i grew up when i did !

anyway.......
after looking on ebay last night someone is selling a non working zt 65 60" plasma. spares or repair for £475 .might have been tempted if it was a fair bit cheaper .
anyway back to original question.
ive looked around a few forums etc and possibly badcaps is the one to join.seems to have more or less everything im interested in .

like i said. all personal preferance and what your own eyes like best.
personally ive never seen a lcd that can beat a plasma and to be honest theres nothing wrong with a good crt. yes crt wont have perfect alignment / uniform convergance but the picture looks real.
plasma to me is the next best alternative to "real lifelike looking" in terms of colour accuracy and realism but every lcd ive seen ( especially your smaller cheaper stuff) just looks false. colours dont look real even if turned down. plus the leds dont last long.cfl better but picture still not great.
partners 65" 700 panasonic plasma is possibly the best tv weve seen .if it ever goes faulty she will demand another of the same although i doubt we will ever be so lucky as we were with this one. £50 non working and only needed a ribbon reseating .
as i say this is MY opinion.( and hers !) dont want to start an argument or cause offence.
its like hi-fi preferance. when i was in the trade we had a listening room with multiple sources,amps and speakers to switch between and when we had a listening appointment we didnt always tell the customer what he was listening to but asked them to choose with their own ears. they often brought their own vinyl to use and were often suprised when their final choice wasnt necesarily the highest priced( and no doubt pleased too)
most listeners couldnt tell differences between cabling unless you told them you were using a better cable and then some said they did. so that makes a question mark over it ?
as we explained .it doesnt matter if the item has won loads of awards. its your ears that are listening to it and if a £200 pair of speakers sound better to them than a £1000 pair then thats the right choice !
same with everything in life . within reason we are all our own boss

like i said. all personal preferance and what your own eyes like best.
Couldn't agree more, and wasn't necessarily actually disagreeing, but...

personally ive never seen a lcd that can beat a plasma and to be honest theres nothing wrong with a good crt. yes crt wont have perfect alignment / uniform convergance but the picture looks real.
A CRT (like a plasma) degrades with every hour its on. On a CRT, its known as the tube starting to go soft (The phosphor coating wearing away, combined with the vacuum not holding as well and contamination on the electron gun(s). This makes the picture less sharp (or "soft"), and leaves contrails.

Back when I did my 224 in colour TVs, a tube's life was deemed to be utterly ended at about 3500 hours.  That's around 5 years with 2hrs per day, at medium brightness.  Also, that was on the tube's softness, not things like screen burn, which happen much quicker. A soft screen still "works" though.

Now your old Great Aunty Ivy, who has had the same TV since 1970, hasn't noticed this because its happened gradually, so is perfectly happy with the blurry, unwatchable mess. And back in the day when the National Anthem played, you could see that white spot forever on a CRT that was more than a couple of years old ;D

Plasma displays degrade similar, but its phosphor (plasma still uses phosphor, like CRTs) and the electrode coatings that slowly degrade.  Again, it makes the picture soft.  Some people may prefer that, but you are losing the detail and it can't display fast motion well.


That's not to say that catastrophic failures don't happen with CRTs or Plasmas - both are more prone to them that LCD sets, due to the thermal stresses.


LCDs don't really suffer this softness. But can still obviously catastrophically fail.  Early LCDs had a real issue with (back)light bleed.  Not really noticeable against a CRT, but because of this a new plasma produced better blacks.  Because of the way plasmas, like CRTs, degrade with use, a 2yr old plasma could no longer produce better blacks, unless that area of the screen had been black for an extended period - so for example, top and bottom black bars on a letterboxed video looked proper black, but a black object in the picture wasn't, as the phosphor on a degraded panel takes longer to stop fluorescing.

More modern LCDs overcome this by tighter manufacturing tolerances (even on cheap unbranded tat), LED backlighting, software controlled area backlighting or by using OLED panels instead which don't need backlighting.


Hope that helps in further understanding your hobbys.

The biggest issue with 'modern' LED, OLED or propitiatory QLED* picture quality is the terrible presets they are shipped with.

If you actually spend some time setting up the picture as YOU like it, you cannot beat them.  As an example, I have a LG 65CX5LB OLED TV in the living room and a LG 60UF850V LED TV in the bedroom.  Despite both TV's being quite different (and running different operating systems), they ship with similar presets.  When I watch TV in the bedroom (usually sport, as SWMBO doesn't like it) I'm in pitch-black darkness, so stands to reason that the picture brightness should be less than that of the living room.  The point I'm trying to make is, if I picked up both TV's and swapped them over, I'd hate the quality of both pictures.  They NEED to be setup for the environment they are used in, and just as importantly, the eyes of the person watching it.

Another note on personal preference.  I cannot stand HDR.  Everything I have watched in HDR (admittedly not a great deal) has looked very fake.  I'm not sure if my TV reverts to a 'preset' when it gets a HDR signal, but it just looks pants.  I'm sure there are others who very much enjoy it.

*QLED is not worth buying.  Currently, the quantum dots cannot illuminate themselves, so it's more of a traditional backlit LED (just a bit more advanced).  Keep your eyes peeled for MicroLED TV's.  They are the future.  :y

yes personal preference is everything agree 100%.
thats true with everything in life full stop.
personally i cant stand the majority of modern things and modern life in general which is why im stuck in retro 1978-1986 land !
when i get old ( older !) and if i start wandering back in time in my mind as some do they wont be able to notice a difference in me !
thats why i intend keeping my current crt,plasmas and vinyl .and my current vehicles .yes i suppose in reality the omega is the odd one out realy as i consider it to be modern ( nearly new ) type vehicle compared to my others. but seeing as ive managed to own and maintain them as everyday use vehicles for the last 35 years then the omega should be a breeze providing i can still get service parts.and also wether i will have to convert any to electric in the future ( lets hope not !)
