Anyone who can help

I have a Polaroid TV ( Model P40LCD12 ) power supply : 220-240 V ~50 Hz 190 w..... My problem started with when i switched it on about a week ago with my xbox i got a red screen came up then faded into black . Everything works but if you have something on screen for instance when you bring up the tv channel at bottom of screen when you leave it it has a red hue which slowly fades away . When viewing tv there seems to be no red in the picture ...seems to be just blue and green working. I have just had it returned by a so called tv tech who said " Its your screen and he could not repair it " i have been trying to find out on Google what the fault may be and that is how i came across this great sight BADCAPS.NET..................I still get red hue even on blue screen , its been running for last 3 hours perfectly ..just no red in viewing even though you get the red hue ..........is he correct can it not be repaired...........Thanks Dod

Re: Anyone who can help

It is hard to get an idea of the fault from the description, is it possible you could make a video or take a few photos of it in the fault state?
From what you've said so far, I would not rule out the possibility of a bad panel (bad screen.)

To me, that looks like a bad LCD panel (non-repairable unfortunately.) I am betting the panel in your set is made by Samsung as this is a common failure point with Samsung panels. (The rest of the TV is made by Vestel; Samsung only supply the display portion.)

Since the fault is intermittent you might have luck with a "tab bond shim" - however the success rate for this method varies considerably from model to model, and in general is poor for Samsung panels:-

Note the fault varies from manufacturer to manufacturer.

Re: Anyone who can help

took about 1/2 hour last night for color to settle ..left it on all night and color has not faulted...you can go any place on settings no ghosting at all ....just seems to be on initial start up.... could there be anything loose inside as I have not checked that yet as I was waiting for your advice...or do I just have to live with this until screen actually goes for good...

Re: Anyone who can help

It will probably get to the point where it will not go away any more. As I linked above it could be a tab bond problem. Technically this is in fact a loose connection - but it's a solder connection between the LCD glass and the driver electronics. Applying the tab shim puts pressure on this connection. In some cases this can be a permanent fix but in other cases it does not last. I am not sure why.

Re: Anyone who can help

I do agree with tom. But for kicks and giggles. You could try to turn off the tv and then turn it back on where its ghosting and take a hot air dryer to the t con board just incase but probably won't do anything.

Hi Tom ...well I had a look inside and you are right the LCD is a Samsung ...I checked the video and put in the "tab bond shim" but does not seem to have helped ...this is what I had after and the color does not settle down really now except when you change to tv but no red in picture but no red lines ....is it kiss good bye time to my tv..
