Oof,that looks scorched alright, there's your problem.
That Definitely is faulty,the external more thick traces are usually where VA goes,look at the SMDs and PCB traces,they're discolored from heat, measure the resistors and capacitors, try cleaning connection and ribbon cable with isopropyl thoroughly. If the TV works without that vertical driver connected,and not with it in, time to sell the boards, make sure to never power the tv without the heatsinks.

It was from a smoker so i cleaned all connection with detoxit and iso then threw it back together. The pins are not scorched just some soot on top. The panel primes but goes out without reeboot when main disconnected and voltages still present. I tested big resistors and fist bank of far left to be good on z buffer. Possibly this soot indicates lt took out the logic board. I tested with z buffers isolated and each at a time. Forgot to get the freeze spray again . i get proper voltages to the resistors on z buffers. I tested a filter cap on psu that may cotelate with logic to be lower capacitance. I cannot how ever get my meeter to do it again.

Wow do i feel dumb. Dose anyone have the nand dump for ic1302? swear i did 3 and 4 then looked at the video. Possibly new ysus gonna try old. The buzzing from this tv seems loud with the back off. i thought it was top pins like the video. i now have a test pattern !

Merry Christmas,

Nice,when i saw that discoloration I immediately blamed the poor panel,good to see that the TV will actually be repaired.
So now you have test patterns displayed correctly but the panel shuts down in one second?

It stays on with main isolated. I wonder if i could use a old usb flash drive to program it like in the photo below. i also have a e3 flasher for a ps3. Would be cool if i could freeze it from below while dumping it with the e3. I also wonder if a TSOP48 chip from a ps3 or flash drive would work. Its gotta be possible data is data right like zeos and ones.

Nand data sheet

Its a 16gb chip that is multilayer 2 bit!

Re: PN59d6500df possibly not ic1302

I got my freeze spray in yesterday. I dont trust duster on this main so i bought some mg chemicals 403c super cold HFO-1234ze areosole coolant. I soaked it and it did not work the first time then i douced the whole board then ic1302 for a couple second longer.it worked for 5 mins then it went out. was hopeing it would stay on After the freeze. Now i wonder if i should freeze n dump ,buy chip, both .

Re: PN59d6500df possibly not ic1302

If you have the files to reflash the chip, do that, obtaining a dump from this NAND even if it's frozen and flashing it with that doesn't seem reliable, but if done correctly I don't see how it could damage anything, at worst it's a waste of time.
The board started working only after freeze spraying IC1302 or at everything?

Re: PN59d6500df possibly not ic1302

I douced all the chips then back to ic 1302 for a few second more to get it going. Gonna try just ic1302 but it also soaks the chip below.

Well after the misdiagnosis by following a video by using top pins. I did try 3 and 4 with hdd jumper but it must of not made a good eniugh connection the first time. I now replaced ic1302 from ebay and the problem is gone !

Can you please elaborate?

How did you read the contents of IC1302?

How did you reprogram IC1302?

Did you have to freeze it to read it? Or did you buy a pre-programmed IC1302?

Please try to be more specific and write your information so it is useful to others.

Thanks.

Re: PN59d6500df possibly not ic1302

I ordered a programer i thought could do it. I was wrong so i just ordered a chip on ebay to save time.
