Re: lcd picture faded to black

my bad, read it wrong, I thought it read went completely black, gilly is right if no light reaction when tcon is rocked, then more than likely the tcon or tcon cable.

i hope so ..
what i did was remove the connector and move it in and out gently
i will do again just to be sure
i really cant afford a new tv at the moment
it was weird when the fault initially occured(months ago, i dont watch tv anyway) i was watching red dwarf and the picture slowly started to get darker...

I guess it's possible the backlight/s are bad or going bad.

I am still not too sure about there only being 5v into the Tcon - I am not sure that is enough. Can you trace back from the fuse to the contact/s on the connector then follow the cable back to the main board and then follow the 5 volts to see where it comes from. Then post a clear picture to show us the area.

Just checked the service manual for my sharp tv with a very similar tcon and that says 5v too. Its marked also on the mainboard as "5v LCD"
