Isn't turning on, goes on for a second then light blinks 8 times


That means the EHT has exceeded 33KV and it will shut down.
Probably caused by a faulty/maladjusted power supply. Check the 135Volt rail.
Hope that helps.

Kv-36hs500 quit working and red light flashes 10 yrs old


This is an indication that you have a problem on the power supply section or on the load because of the following reasons :

1. Over Voltage - the regulator might be cycling on over voltage due to lack of load.

2. Over Current Protection - excessive load or faulty power supply cycling will

trigger the over current protection circuit.

3. High voltage - there might be an excessive high voltage or some other system detecting an out of regulation condition. However, in this case, there should be some indication that the deflection and HV is attempting to come up - momentary whine, static on the screen, etc.

4. Leaky Capacitor - a dried up main filter capacitor or other filter capacitor in the low voltage power supply that is producing an out-of-regulation condition. A bad filter capacitor on the output of a series regulator may result in excessive/drop of voltage causes your unit not to power up unless isolated.

5. A problem with the microcontroller, relay or its driver, or standby power supply.

This is not DIY and quite technical so I've advice you to look for a qualified technician or send it to repair shop to isolate the problem.

KV36 HS500 7 BLINK PROBLEM


  • Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
Hope that helps.

Standby light blinks you hear the contactor clicking in set, no audio and no video displayed. sony kv-36Hs500 only looking for response if this is free of charge


this symptom is usually caused by a breakdown in power supply circuit or it may also be caused by a breakdown in the horizontal deflection circuits which includes horizontal oscillator, pre drive or drive circuits, horizontal output transformer, horizontal output transistor and high voltage circuits (flyback transformer). pls observe precautions in dealing with this high voltage circuits and if so happen you are not inclined with this kind of work, it is better for you to bring it to a qualified technician to avoid accident. good luck!

My tv stays on favorite channel menu and I cant get it to change to video. The remote only powers on the unit and wont change anything or turn off. The menu on the tv wont help. Please help


Sounds like you have a stuck button on the front of the TV or a bad protection diode in the keypad matrix that will need to be looked at by a technician.
