Like the title says I get no picture and no sound from the tv. I check the fuse and it is fine, not blown. I opened up the back and took a look at at the LED in the back to see if they're all lite, and they are. I don't think its a conversion problem either. So I'm stubbed. I can hear the tv power on and the power light on the front stays steady on. I visually checked the circuit board and there was nothing apparently wrong. I even used a wooded stick to poke a some IC to see if there i was a crack in any of the solder joints. Anyone have more suggestion that I should look more closely at?
It needs convergence ic's.This unit has a auto-blank circut if it detects a problem with the conv. ic's

m1013, would it be visually apparent that the convergence IC's are bad? Like it looks burnt/melted?
I did the convergence ic and resistor swap and It still does the same thing no picture. Any else suggestion what it could be?
the red on light on the front comes on but nothing else. what is my first step?
I have the same problem with the same tv but i dont think that its the convergence ic because the the power supply output to the power\deflection P.W.B. is wrong. I read -36V when it should be +14-18V.
How do I fix this? Step-by-step instructions would be great!
