Thanks for waiting, 8 times flashing error code indicates following possible failures.

Abnormality of the Sustain drive circuit.

Open or loose connection between the SS board and FPCs from the panel (SS61, SS64, SS21, SS24, and SS58).

Open or loose connection between connectors C10/C20 Open or loose connection between A20 and SC20.

Wrong diagnostic by the A board.

8 Blinks condition is also caused when the connections between the panel’s flex-cables and the sustain board are broken or the connector are not properly seated.

Possible failure is either SS board or display panel or A board or C2 board.

I trust my input will help you out. Please feel free to respond if you have any additional questions.

hi i was actually hoping that you would be able to assist me in diagnosing the exact problem with some sort of procedure as i basically found the same thing on google by searching and checking all the connections, and i still have the same issue. i might just take it into a tv shop if you think it might be a bit too hard to do over computer correspondence. If you could let me know that would be good.

I wish there was an easy or quick fix or troubleshooting procedure except I outlined in previous reply.

Did you swap/ replace any board mentioned in previous reply?
