Hi guys,

I've got a Sony KP-41T15, when the TV is turned on, I hear two relays click, then I hear the high pitch sound (similar to a CRT TV starting), then another relay clicks, and the timer/standby light flashes twice.
Anybody familiar with this problem?

The TV is a 41" projection TV made in October 1995. I have electronics experience but not with televisions. Any advice would be appreciated!

Thanks

Check your fuses on the convergence board. It has the STK392-110's on it. If you have open fuses replace the IC's and the fuse.

Thank you! I removed the standup board, found STK392-010's that showed signs of being replaced (solder, excessive thermal paste) and a blown 3.15A fuse. I will be putting it back together and will post the results! Thanks again,
