Sony Trinitron won't power up

if the power went out all that may be bad is the fuse; follow the power cord inside the set and it will take you right to the glass fuse; these sets also had problems where the power supply in them fails--several parts get killed instantly--if this is the case---good advice would be to look for a new tv.

No power to my KV-32V15

Unplug the unit, wait at least 30 minutes before beginning work after unplugging. take the back case off, there are 10 screws I believe holding it on. Where the power cord goes into the unit, look on the circuit board and you'll see a fuse. Check the fuse, I'll bet it's bad. Replace with the exact same type. I have the same TV, had the same issue. I'm now enjoying it just as I once was. Good luck.

Remember to be VERY careful when inside a TV, there are power sources that are fatal.

Sony 36" Trinitron Problem

Good day.
There may have been some problem in the horiontal transistor. Also, Check for the zener diode that controls the supply going to the flyback. It might got busted due to the sudden supply surge.

Trinitron KV-36FS13

The problem is in the standby power section. Check the fuse, R607, or burnt IC601, fuse R612 and VD relay 601 should show open. Its possible it could be the high voltage area of the power supply. You can try unplugging the set and cable and let it sit 4 to 6 hours. This is a hard reset. If it still doesn't turn on after the hard reset and the fuses and relays are fine, and you don't smell anything or see anything burnt. Then you'll need to call a TV repair man. They normal start around $150-$200 to fix the set. I hope this helps.

Remote doesn't work

Possibly some of the dry wall dust could have gotten into the buttons on your remote. You can check the remote by holding it close to an AM radio receiver and listening for popping sounds as each button on the remote is pushed. You may have to move the remote around to find a position where the radio will pick up the signals. (usually close to the antenna ) also you may have to tune you radio up and down the dial. With this method you can test each button on your remote! Hope this will help you! Stargazer
