Is this a bad T-Von?

[Nikolai Tesla]

Hi,

Got this Sony from a friend, a Sony KDL46-EX500, I think it's the tcon but I'm not sure.

Anyone with a good tcon and a remote please write me.

Ps even with a Sony remote the red led doesn't blink . Is the remote board dead?

I'd say mainboard.

Well bad tcon boards don't usually produce horizontal lines, none the less you could try disconnecting one at a time left and right feeds from the tcon to panel and see what changes you get.

Guys, I made some NEW photos..recheck my album please. On HDMI2 no horizontal lines. But maybe artifacts (I'm Dutch, not a native speaker).

check the main board.you need to check coil packs.try to replace them or use jumper.trace lvds connector you can find them.if you cannot see the coils clean the ribbon.

you may have a gamma issue, but i can't see the vgma test points on your t-con. there may be some on the panel driver board. your gamma chip is the maxim chip.
