Oh well skip it is then!!

Not a matter of it being worth it -- it's simply impossible without the equipment, sadly. Now, they COULD make the connectors removable (the density is low enough for that to be OK), but they don't.

So there is no way its even worth me attempting? Man I hate this throw away society that we live in!!

Thanks a lot for your help Tom66 I really appreciate your time.

A multi-million pound laser welding machine and precision alignment equipment.

Is that all? I have one of those in the back yard lol

Re: HELP Please with faulty TV

No I have tried each component and there is no joy. I know you say you cant replace the T-con but I wouldn't mind giving it a go. Don't suppose you know what soldering technique they use to attach it to the panel?

[tom66]

Re: HELP Please with faulty TV

It's a shame the T-con can't be replaced. Does any other part on the T-con respond to freezing?

[Berts]

Re: HELP Please with faulty TV

That's a negative, absolutely no change when either of the tabs was frozen. The only thing that cures it is disconnecting the t-con then reconnecting. The hue doesn't come back straight away but takes the same time as if starting from cold.

Re: HELP Please with faulty TV

Try freezing one tab bond or the other and see if it immediately gets better.

Re: HELP Please with faulty TV

Yes it stays on 12v. Where do you think I should look next or do you think I should just give up?

[tom66]

Re: HELP Please with faulty TV

Seems fine then. It's pretty much guaranteed to be t-con or panel, sadly, I think something on the panel is knackered. Can you get hold of a can of freeze spray?

Re: HELP Please with faulty TV

Tom, bang on 12v that's whilst the set is doing its red hue thing.

[tom66]

Re: HELP Please with faulty TV

Sounds good; is it stable when the picture goes red?

[Berts]

Re: HELP Please with faulty TV

Tom, I am getting 11.95v across the fuse. I am guessing that is good?

[tom66]

Re: HELP Please with faulty TV

There should be a fuse on it.

Voltage is measured at both ends with red probe on each end, black on chassis.

Re: HELP Please with faulty TV

Not sure I know exactly where to test for the voltage.

[tom66]

Re: HELP Please with faulty TV

I think that would quickly risk damage to the LCD panel. It's not removable from the panel. Other things to check would be the supply voltage to the T-con.

Re: HELP Please with faulty TV

Yes I have tried cold spray and could not find the cause. If it were a temperature sensitive component I would assume that unplugging the T-con and re attaching it so quickly would not have the effect I am getting. The hue takes just as long to come back after the quick unplug as it does if I start the panel from cold.

Do you think the re flowing the T-con panel would help. I have various equipment round here to do it. I could even use a hot air wand to resolder each component if you think it will help?

[tom66]

Re: HELP Please with faulty TV

You may have a loose cable, temperature sensitive component or cold solder joint on the T-con. Regional heating or freezing using cold spray (compressed air works too) may help find where the problem is.

Re: HELP Please with faulty TV

Tom, I tried the points you noted above and cannot get any reaction. I did however find that if I let the red hue start and then removed and reattached the T-Con ribbon cable the hue disappeared instantly?

I have included another video for your review if you wouldn't mind taking a look and sharing your thoughts?
