Hopefully I’ll be able to save someone some repair money on their Sony Trinitron TV someday. A couple days ago the standby light started blinking when I would try to turn on my TV. There would be no sound or video, just a blinking standby light. This has actually happened several times now.
The first time I took the TV into a repair shop only to be told the next day that it worked just fine. I came and picked it up and it was fine.
A year later (now) the same thing happened. After some investigation I found that the number of blinks given by the light should provide some information. Mine was blinking 7 times which was probably indicating some power issue. I left the TV unplugged for 24 hours and then plugged it back in – on a surge protector this time. It has been working just fine since then.
Good luck if you’ve got one of these Sony Trinitrons. My model was the KV-36HS500, but the description I found online was for a slightly different model number.
