Re: Sony KDL55EX720 won't turn on



The one we just worked on had the same issue, 5 Red flashes.
Worked through service manual schematics and this thread troubleshooting along.
Found the corrosion from over cleaning spray.

Left 1/2 panel worked with only 1 flex cable connected to T-CON, found the charred traces on the panel PCB that was not working.

Once we cleaned it, and reconnected everything, the panel came on with full picture.
But only took 15- 20 seconds for bad panel PCB to get hot where the traces were...
