Re: Sony FD Trinitron Wega

The power supply board is failing. There are twi integrated circuits in the horizontal drive circuitry that have to be replaced. The original integrated circuits are the same type and you will see written on each..."MCZ3001D" and need to be replaced with Sony # 670581001 or the "D" board with those parts on it needs to be replaced. The cost of the entire board is high-about $375.

My KV-36HS500 won't turn on it sounds like it wants to,but no picture,and standby light flashes 7 times,pauses and flashes 7 times again

The 7 blinks indicate that the horizontal deflection has stopped. This can be because the horizontal output transistor has shorted (common) or other defecive parts. If you are familiar with working inside of sets where potentially dangerous high voltages exist and can solder, let me know and additional details and instructions will be provided.

Sony KV Trinitron WEGA 36" TV won't turn on

My 36 wega did the same thing last week it must be contagious. Blinks 7 times mostly but sometimes 6 if hit power switch again. The problem is the D-boards shorted Flyback high voltage transformer but the ones Sony is selling $130 do not hold up and seem to burn out in a few days, yes twice bitten. Finally they send me new D-board can't wait to see if this fixes it once and for all. The board costs around $200 but is worth it to get it running again.

Seven Blinks: High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into shutdown. Check power supply and horizontal circuits.
