32" Spectre -- T-con issue?

[aaronwt6]

Picked this set up with a bunch of others. Mostly broken screens but I bought them as a lot and got a couple that are fixable. This one was brand new and still has the stickers on it. Anyway, I'm pretty sure this looks like a T-con problem but thought I'd ask for a few more opinions. I wouldn't normally even buy one of these but it cost less than $10 so I figure I may as well try to repair it.

As you can see in the pictures the colors get this kind of white, almost ghosting in the images. Especially lighter colors.

Thanks as always,

Aaron

Oh, and if it makes any difference it's an AUO panel.

Looks like solarisation - main board problem usually.

Re: 32" Spectre -- T-con issue?

Ah, ok. New term for me. I'll see how much the main board runs. Don't want to put much in to it but again for the price I paid its hard to go wrong.

Thanks Tom

Can just be wrong panel setting, see if you can get into a service menu.

I guess : GAMMA IC on T-CON is NG.

Check all the gamma voltages .

Re: 32" Spectre -- T-con issue?

It is unlikely to be gamma voltages because of how sharp the transitions are, when the gamma chip goes bad the transitions are still smooth.

I'm at work right now but will check when I get home. Of course I'll have to see if I can find out how to pull up the service menu too.

Re: 32" Spectre -- T-con issue?

If anyone knows how to get in to the service manual on this thing, I'd certainly appreciate the advice. Model number is X32. I looked around briefly but didn't see anything.

Re: 32" Spectre -- T-con issue?

So, turns out after trying a tcon and main that the problem was a bad ldvs cable. However, on to my next issue. After watching the TV for a few minutes I went to reconnect the ground cable from the power supply to the Tcon with the screw that goes into the power supply and managed to slip (tv was unplugged of course). Stored charge I suppose and the ground clip his a transitor and let out the magic smoke. Part number JCS2N60F. I only see them in China and was wondering if anyone knows where I can get one stateside. Feel like a real dumbass right now.

Thanks again,

Aaron

It's probably just a standard 2N60 device, they are quite common e.g.

Re: 32" Spectre -- T-con issue?

Wonder if I can find one on another board I have lying around. I have no 5VSTBY or anything now. Would that make sense?

[aaronwt6]

Re: 32" Spectre -- T-con issue?

Oh, I see where you said N60. I'll keep looking around or order one.

Thanks Tom as always

That's my 'go to' Blu-Ray for testing TVs. Sometimes testing turns in to watching it on a 50"-60" in the garage from 3' away.

Got the PS repaired on this and it's good to go. Guess I'll be a little more careful with the reassembly next time. Thanks Tom for your help as always.
