Power Supplpy board is dead.Replaced the power supply board will solved the power flashing.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
was the lamp blown if it was blown you could be hearing the ballast
if the lamp was not blown and the new one did not fix it the red light indicates the door there is a little switch when you put the door back on if you look at it it may need to be adjusted so it will connect with the door if that is not it you could have a fan that is not turn if it is making a real loud constant humming noise while it trying to fire the lamp you probably have a bad color wheel
hi there, this may seem like a sstandard problem, but differs from mfg. to mfg. in the sony tv's it is usually an open cap in the stand-by power supply, since you werent specific in your problem, there can be many solutions even for a single series or group of tv's even within the same mfg. give me specifics and i can answer more precise. hope this helps even a little.
