Sony kv30hs420 turns on and off again after 3 seconds

Hello. my sony tv turns on with sound but no picture and after 3 seconds turns off by itself. i also noticed that the red standby light blinks 7 times in series. i cannot afford to buy a new tv at this time so do you think it's worth it to be repaired? i have no idea yet how much the service will cost.
hope you can help. thank you.

Check this tread, I had a similar issue you might want to try and tweak the focus and green pots. You will have to remove the rear cover to see these adjustment pots

Will only turn on for about 3 second with no picture and then turns off. Standby light blinks 6 times

For the KV30HS420, 6 blinks, pause, 6 blinks, etc. means "LOW +B OCP/OVP (overcurrent/overvoltage)" and the probable cause locations listed are as follows:

1. +5 line is overloaded (A, B, M boards)
2. +5 line is shorted (A, B, M boards)
3. IC504 is faulty (A board)

hope this helps John

Try unplugging the TV for about 10 minutes and then tunung it on again. Try a factory

To reset the TV to factory settings
Turn the TV on.
2 Hold down on the remote control.
3 Press and release the POWER button on the TV front panel. The TV will turn itself off,
then back on.
4 Release .

I'm assuming step 2 means hold down the power button.

Sony KV30hs420 0 Stanby Light Timer Blinks 3 times and powers TV off

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. If you have electronic knowledge you may be able to fix it. Let me know if I could help you further.
Hope this helps.
