Tv picture issue

Hi

I have a one year old Prima flat screen. The colour of the picture is now sort of blue and purple and the picture slides down to a blank screen with verticle lines. This is the exact same problem with the previous TV (Different Brand) that also lasted less than a year.

The same problem presents it it is hooked up to the cable only or the DVD only. This house is only 3 years old and I am wondering if there is an issue that is not related to the TV.

I called Cable and they assure me there is no signal amplifier hooked up.

Is it possible there is an electrical issue?

'issue' -what's that? i think you mean 'problem' !

this is likely unrelated to your household voltage, as the fault is too specific. normally things just die or explode if the volts are off ;-) I assume you have a plasma or lcd Tv? if it is a CRT then it needs degaussing in the first instance.check also the connecting leads and try it in another room. we need to narrow down the possible causes of this odd behaviour.....

Good suggestion.

I took it downstairs and not problem (not even an Issue!!!!). It can't just be a cable issue though because when the cable was disconnected and only the DVD player connected the picture was just as poor. Any more thoughts?

Is it possible that it may be a different brand but made in the same factory with a different name plate?

By the same Chinese worker on the same Friday afternoon, shipped in the same container on the same ship, distributed by the same distributor?

Simple answer in either case: Ain't friggin' likely.

But possible....

It wouldn't have to be the same worker or shipped the same day. My point is his problem is very specific and this specific problem occurred in two TV's. Would it then be wrong to suggest that if these TV's were identical then they may have an identical design or part flaw that would show itself as an identical display problem?

In these low cost TV sets, the CRT's fail often causing loss of proper colour tracking. Vertical lines or defects in the vertical scanning are caused by component failure in the vertical amplifier section.

The TV would require proper troubleshooting and service to put it back in to good working condition. I doubt it is worth it. If the TV is still under warranty, send it back. Otherwise, you will have to go out shopping for a new one to have a good TV set.

Stay with the big brand names, and you should have less problems. It's worth the extra cost!

It is possible that one of the AC phases coming into your house is not correctly wired. There may be a poor ground/earth connection. Allowing noise onto the power circuit. Moving from one part of the house to another may have moved you to the other phase (in the us, 220 2 phase is brought to the house and some outlets are fed from one phase, some from the other.

You may have a device that is putting a strong signal of some sort onto the AC line, that signal feeding through the power supply circuits and upsetting the vertical sync.

if it is ok downstairs then there may be something with a strong field upstairs affecting the image. or as others say, check what is running on the same power line - maybe washers driers etc which may have noisy motors or some thing with a bad switch mode power supply. its a bithbard to diagnose without seeing it, as we haven't got much to go on....

Balderdash. :)

The OP said this is a "flat screen" but is it a CRT set? Someone else mentioned this, but no apparent answer. If it is a CRT, sounds like a magnetic field issue. Did you just install a megawatt stereo near the TV?

quite possibly. :)

He seemed to indicate that the problem occurred AFTER a period of time, rather than immediately. It would take one HECK of a magnet to 'sort of slide down' the picture. I usually get a pretty rainbow effect with some picture distortion, depending on where the magnet is located.

[if you want to have some fun, dig a hefty magnet out of a magnetron or old hard drive, mount it on a rubber band, carry it around behind a CRT monitor or TV and spin it while someone is watching the TV or working on their computer. It is most effective if you can do this in the next room so they don't see what you are doing. :)]

Of course, if any crop circles have appeared in his neighborhood recently, THAT might explain where such a magnetic field could come from. :)

It STILL sounds like something coming in on the power lines because he sees it from the cable or from DVD only.

Maybe he is going through the same decoder box in both cases and THAT box has a problem.

A neighbor tossed a recent model CRT TV onto a rock pile fact down; after rescuing it and a cleanup and powerup, the CRT showed color distortions where the shadow mask was dislodged. Bringing a magnet near the neck of the CRT close to the purity magnet rings, I felt a strong 10 Hz pulsing about five inches from the tube. Moving the magnet closer than two inches produced pulses almost too strong to retain a grasp on the magnet.

Not having a schematic of this set, I can only conjecture on the cause. Do recent model sets have some sort of servoed pincushion correction or other control loop running at 10 Hz?
