Re: JVC LT-32X667 with a grey screen

I had some time to go over everything with a meter and there were some incorrect values on random parts but the D-AMP PWB had some of the most consistently off.

Any advice on what to do/check next?

I plugged this into my linuxbox and started up xserver with nvidia's debug mode on and it read the edid no problem, so I know the thing isn't completely fried.

I read that 90% of the time it's the T-CON board and although the fuse on it was ok I ordered a replacement anyway. Well the replacement just came in and I popped it on and sure enough I'm the lucky 10%.
