Dear Sir/Madam,


5 red LED blink problem with a singing power supply. Turning on and off, normally twice. Try hard reset.
Most likely the SC board. Sometimes an SU or SD will go bad and take out the SC as well so carefully check the surface mount ICs on the SU and SD for small cracks, bubbles, or other signs of overheating.
Be careful if you choose to look at this yourself.


Thanks
good luck

You are talking about tv right

Unplug the power cord for 3 hours. This will totally discharge the internal eproms and empty out any old memory data. When you power back up it will reset to factory defaults

A possible loose wire connections / signal have result the problem.

check the connections.
