The relay goes off because the safety system in the power source detects an overload and shuts the source down to protect it. On a tv this old the first signs of old age begin to appear. Open the tv and look for failed capacitors on the power source and the Y-sus boards, then check the voltages.

I have no picture. i have sound and the power light is on


This can be tricky in this set I have replaced ps, logic , sdr u and d, and I think my problem was Logic board at first. There were lights on this board that goes back and forth like the Kit car, this tells what is not working. This can be very expensive in the shop. But it's complicated also.

T V Goes on to Green Light Yet Box Stays On Red


I have an AV3000E that developed this symptom following a 5 second power cut.
I downloaded the manul, suspecting a power supply problem. The way the AV3000E works is to have a 5 volt power supply running all the time, this powers the main processor. The main processor then energises a relay (S901) by applying 5V DC between relay pins 3 and 4. The relay contacts switch rectified mains power to the main switching regulator. The replay was being energised but appeared not to be switching. While the AV3000E was connected to the mains, I carefully I connected a short between relay contacts (1 and 2) while the processor was trying to energise the relay coil. The TV burst into life. I removed the short and the TV continued to operate normally and has done so ever since. I cannot entirely rationalise why this has worked as this should not have fixed the relay, what may have happened is that the short power cut may have resulted on the some corruption of the processor non-volatile memory, and that the incorrect operation of the main relay caused the processor to reset it's internal memory.
BE WARNED, WHAT I DID WAS EXTREEMLY DANGEROUS AS THE RELAY CONTACTS I SHORTED ARE CONNECTED TO THE MAINS SUPLY - YOU ARE LIKELY TO KILL YOURSELF IF YOU DO NOT KNOW WHAT YOU ARE DOING - PLUS I TOOK THIS ROUTE AFTER ELIMINATING THE OTHER OBVIOUS PROBLEMS LIKE FAILED FUSES.

if the tv is completely dead, your first step is to check the fuses in the power supply.but if you get the standby light, and nothing happens when you hit the power button, you need to call the repairman


good luck
