Re: Sony KDL-55EX720 5/7 Flash Error

Just tested. Looks like panel took out the t-con. Thanks.

Hi, so this is where I am currently at on my Sony KDL-55EX720.

My TV was struck by lightning (on a surge protector) but still got hit.

So this is what I have troubleshooted and where I currently am at.

TV won't come on, and am getting a 7 blink error code. This is typically indicative of a bad main board (BATV board per sonys service manual). So i ordered a replacement and swapped it out and now I have a 5 blink error code so I am assuming the main board was bad. I put the old one back in at still 7 blinks.

5 blinks per sony's repair/service...

Re: UN55ES6500FXZA (TS01) Horizontal lines/Double Image

I will try both the youtube video suggestion and removing the ribbon cable on each side of the t-con. can you point me to the other thread that the guy fixed it? just want to see what specifically was successful for them. thanks.

So let me fill you in on what I have done so far, and where I am at. I have a basic understanding a TV repair. Checking voltages and what not. Majority of my skillset is in just replacement of boards, not physically soldering on new ICs or anything.

I have a UN55ES6500FXZA that is giving me weird picture issues. After seeing enough issues I think I have it narrowed down to a bad T-CON,LVDS, or "bad panel".

I first ordered a used T-CON for my TV. The used T-CON was pulled from a UN55ES6580FXZA with a cracked screen. The part numbers matched and it was BN95-00579B....

Re: New Members - please post your introductions here

I've got 15 years of HT/PC hobby background and I just have started to get serious about TV repair in the last 3 or 4 years. I've repaired and diagnosed about 150 TVs in that time.
