SOURCE: RCA Model F36450 Chassis ATC113CA1 won't power up
No sir it probably isent a power supply problem as in these sets it wouldnt act like that. First thingm to check since you say your a service tech, is in the horizontal output check and see if the horiz. output transistors shorted. If its not then check a small coil off the base of the horizontal output transistor. its really the base drive coil so take it out and scrap off the ends BOTH ENDS and reinsert and also resolder the horizontal driver transformer. This may or may not fix your problem But if it dosent order if you think ther sets wrth it the flyback transformer as this is a big problem in these sets if the for mentioned things did do the trick. follow the kit instructions that come with the flyback transformer!! Dont take any short cuts. Make sure you do take out the horizontal output transitor or at least unsolder all the leads when tesating it for a short. Good luck

This could cause a problem, because modern TVs and most other entertainment electronic goods, have a small kind of computer chip, but there should be a Reset button probably inside the set! If you feel confident about computer chips you may be able to find the button by tracing the circuit.(Disconnected from the mains). Another idea is if there is a small button cell or battery inside, then try disconnecting it for a day. Good Luck!

If you blew the fuse, the TV would do absolutely nothing - no lights, no sounds, nothing. It could be that the loud zapping noise you heard was the high voltage transformer arcing or shorting out. This could have caused the horizontal output transistor to short, and the set will not start as a result. You should have the set serviced by a qualified tech.
