Re: Sony KDL-65W850A Dead

Unfortunately the panel is all taken apart, I want to make sure what's wrong before reassembling... Would swapping that IC resolve a panel ID error? Is there also an eeprom IC that could be the problem?

O:HH.. now we do know you still have the panel out side the set LOL the fault you have now because of the panel not connected man.. you should put every things back .

This was same issue before I removed panel though, after replacing main board.. But I will try it..

Re: Sony KDL-65W850A Dead

But the panel back in.. no change.. It doesn't even attempt to turn on past a click and then click right back off.. Maybe a slight flash of backlights..

Any Sony techs out there, what is this orange/green flash mean!?

Well I downloaded the latest software and put it on a USB drive, and plugged the TV in.

I saw some activity on the drive so I left it alone for a while. Came back and there was no more flashing lights. Unplugged the TV, removed drive and plugged in the TV again, and BAM the TV came on with OSD and a snowy pic from the tuner.... for about 5 seconds, then went out with the now 4 red blinks..

I guess we're making progress!!

Re: Sony KDL-65W850A Dead

Well getting to this point was a huge break thru.. then finally getting a blink code error (4 blink error = LED error, LD_ERR).

Well I had a LED driver board I had ordered when I first got the TV. Put that in and TV finally seems to be fixed!

So it looks like at the end, bad:
1) Main board
2) Bad LEDs
3) Bad LED driver
4) New main board needed software update to work

Wonder if it was hit by lightning...

But a nice 65" with minimal cost and a LOT of labor. Thanks for all the help on this one!

Re: Sony KDL-65W850A Dead

ive read this thread a few times now as i have the same model which was apparently knocked out in a storm where i have no standby light and no volts on the secondary "12v" side of the power supplies, i have replaced both power supplies with no luck so next is main board and firmware upgrade, from what i can gather from the thread the driver was the last thing to be replaced so were the LED'S faulty at all?

Hello. I'm having problems with this same TV but a 5 blink error. I don't know if asking here would have counted as hijacking or even posting this here so I made a new thead. Thank you.
