Sounds like a DVD player issue. The TV is all analog and can't replicate issues like that.

No sound, no picture standby light blinks 5 times, pauses, blinks 5 times, etc. This is a Sony Trinitron 36" Wega tv about 7 years old.

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

My sony trinitron turns off by itself and then the stand by light blinks five times then pauses for like 4 seconds then flashes 5 times and repeats

This is picture tube related problem and we call it incorrect white balance.
Adjust Screen Volts of picture tube and control knob wold be located on flyback transformer. If you have knowledge about tv and know that tv contains high voltage and you can take care of that then do it yourself or ask local tv repairman to fix it.

My Sony Trinitron won't turn on...has 4 blinks in Standby.

This may be a vertical circuit problem. IC1509 is usually the vertical IC. If you can solder, I would first try an resolder the pins on this IC. If that fails to resolve it, replace the IC. This IC is a small flat IC attached to a heat sink with about 11 pins. It will be marked LA7837 or something similar. Feel free to post the marking and I'll confirm you have the correct IC.

Keep me posted.
