As many of you will know i've only recently started out on this tinter thing but for awhile now the monitor's been flickering from normal to blue then settling in to normal. However it's all "bluey blue" most of the time now.
It all came as a bundle box from T***o as p* w***d told me i needed to buy this, that and the whole store really. Anyway i've got 2 yrs warranty, 1st (still in date) with T***o & 2nd with Ph****ps.
Been told by mates that they'll replace it as cheaper than repair so i do'nt have to be offline.
I've got purchase reciept & paid by switch so what should i do next?
It all still works fine & the monitor's got "iQon" logo. :-/
-
get an lcd and protect your eyes ;)
it could be cable, but also likely dry joints on back of tube if crt...
-
As TB says, worth giving the cable a wiggle and make sure it's properly plugged in both ends.
Otherwise, take it back under warranty. Or use it as an excuse for a flat screen purchase!

got to be honest, although i got my city & guilds in tv repair, I just rang up Dell today as my tv has an annoying intermittent fault. I just couldn't be bothered to investigate. New one arrives tomorrow.

We live in a throw away society. Even though it's new they'll probably give you a new one. I'd check the wiring then give it a thump - tried and tested method of TV repair where I come from :y

That's a point.
Does the logo / on-screen setup display of the monitor come up normally or are all the colours FUBAR on that too?
If the OSD has dodgy colours it's definately something internal like tube connections as TB said. If not, could be cable / connectors or outside chance it's the graphics card (unlikely).
Do you know someone with a spare they could lend you a) to verify it's the monitor and b) to cover you for any down time?

Even in the days when things were built properly TVs were a PITA to service IMHO. Either everything working or smoke escaping ::). They're too big to work on these days too. I know a guy who runs a small TV repair shop and if you call in within 2 weeks of a thunderstorm you have to hunt for him behind the piles of 36" TVs. He's a big chap too, so not normally easy to hide ;D

I had a 22inch CRT that did this good make also but in the end down to the tip with it as it was doooing my head in and making me see double :o I found out before it went to the tip that it was one of the guns had started to die

Nah, I learned on KT3 and even G11 type chassis, easy to fault find and service... ...unlike her telly in kitchen that packed up a couple of weeks ago, though fortunately that was just a fuse...
-
I had this problem ages ago with a dell 17" crt, I just kept giving it a whack and it would work ok for a few days, then whacking didnt work, so I removed the back cover and wiggled the silver box thing on the back of the tube and found it was coming off, one shove back in place and all was well untill the mrs spilled coffee down it ;D Im on 20" LCD now, no looking back :y
-

I guess I need more practice ;)
I have a "problem" (SWMBO's words) with Tektronix 'scopes at the moment. Can't pass one at a junk sale without "saving" it. 5 project 'scopes on the go now, I think. ;D
Keeps me out of mischief, as I keep saying ::).

We might get em exchanged....but dont think you;ll get a new one unless your lucky.....ok shop might give you a new one.....but if it gets sent away and then a replacement one is returned....it'll be a repaired refurbished one.....might look new.....ie cover has been changed....but innards will be a repaired return ;)
-
:(More worried about being offline. It is a flatscreen, wiggled behind screen but not looked at other end yet. Silly thing is it's bright as a button now i'm off to bed!
Night. :-? :o

I have a rather nice Techtronix 564 oscilloscope....its got valves the lot in it!

My first Tek scope was a 546. Still got it. It got donated to my school by Marconi and the head of science couldn't work it so I talked him into selling it to me, nicked my mum's wheelbarrow to bring it home and promptly got a bo77ocking for bringing "more junk" into the house.
Junk it wasn't, however. It's still absolutely flat to 50MHz+, triggers up to 150MHz no problem and, at 500 watts power consumption, it keeps my attic room warm in winter! It's a hybrid of valves (dozens of them) in the timebase and power supply and transistors in the vertical amps.

Re the monitor, if the colour changes when you (Gently!) thump it then its prob a bad solder joint. This happens a lot in TV's because of the heat making everything expand/contract esp the soldered joints. Now they have stopped putting lead in solder, things are going to get worse. TEK scopes are great, I had a 465 for many years, and recently replaced it with a 2465, which I bought from the US. Its quite cheap over there now thanks to the exchange rate. I also have a 2465B that I am trying to repair, but getting spares is a pain. I mangaged to get a 7000 series mainframe along with some plugins and a 7L18 spec analyser. Thats really great for being flexible, trouble is its very heavy and needs a substantial table to suport it!. Maybe its being used to them, but I prefer analogue scopes to digital ones, what you see is what's actually there at the probe, not what some computer thinks it has got along with anti alias filters etc.
-
I think the 465 was probably about the best scope they made. I have a 2236 which works nicely but a sod to work on and clearly built to a price, which none of the earlier 'scopes seemed to. People say good things about the 2465 but I haven't played with one recently.
I have 3 7000 series at the moment. a 7904, 7603 and 7623. Would love to come across a spec ana plugin but they seem quite rare.
I agree that digital 'scopes don't "feel right" in comparison to analogue scopes. The slightest flicker of an analogue 'scope tells you something, which you'll probably miss with a digital scope. However, it's mainly down to user interface and a slightly different approach being required to use them, IMHO. A load of menus to wade through doesn't seem to be a match for a couple of switches on the front panel.
The better digital scopes do work very nicely and don't mislead because they use plenty fast sample rates, but if you're not working on stuff that needs to be ruthlessly fast and you don't need storage, you're still better off with an analogue scope IMHO. I think the mistake Tek made was dropping the analogue scopes from the bottom end of the range because their low end digital scopes are nasty.

Its the introduction of bloody windows on scopes thats the worst bit.......its like an anxiety detector, it crashes or goes into screen saver mode just when you need all your hands to hold probes and trigger events....

Yes, it's happening to our instruments too. Customer wants to put his spectrum analyser on a network and he also wants to print the screen output. Rather than adding a printer driver and a network stack to the nice, fast purpose built GUI and RTOS the machine has, we port the whole lot to Windows. Now it needs a hard disk to hold all the bloatware that isn't required for a spectrum analyser, it needs virus checking, a much more powerful CPU and customers keep sending them back cos they fall over when they try to install MS Office on them >:(

:DThanks all. I've pulled the lead in & out a few times( oo-er) & blown into the end ( Chopsdad, do'nt even say anything!!!) & we seem to be firing on all 6 again ::) :P :o ;D
-
If its a lcd monitor and it goes when you move it just get a new lead,
i just had the same problem for 3 months.

My TT one has valves, think they may have gone a bit soft though... ...really must get something a bit more up to date (and faster!)
-
Problem seems to lie at the tower end of things, ok at the mo. :y

Always lots of nice Tek ones always going on ebay for very little cash. Bit of switch cleaner and change the dried up caps and they're fine.

I know what you are saying about the 2236 being a sod to work on. I have a friend's 2235 with a power fault, and trying to get probes in to measure things is not nice !. Also they started using custom parts in the 2465 series which are impossible to get new, and one of them the Horiz output I think tends to fail, so if it goes you have to pay about £130 for a replacement, or scrap the scope. :'( Mind you they are very nice to use when they work. :y

Mine failed with a power supply problem. I suspect the cooling fan packed up, closely followed by the MOSFET in (I think) the first stage switching regulator that takes mains down to about 50 volts DC IIRC. MOSFET is mounted to a heat sink just in front of the cooling fan IIRC. Mounting arrangement looked a bit marginal too so I replaced it using a proper mounting kit. That part runs hotter than I would like but has been reliable since.

Thanks for that, I'll check on mine.

:oWent to T***o today and was told to bring the lot in for a refund and they'll throw it all away.
A:- What a waste, tower, speakers, camera, keyboard.
B:- I broke the printer so no longer have the whole lot to take back.
C:- Phone the warranty people.
D:- Fuctifino!!!!!!!!!!! :(
