JVC AV-48WP55 won't pwer up.

Start at the wall plug. Did a breaker trip for that outlet? Next use a multimeter to check voltage at the power input to the TV where the power cord connects to the mainboard. Be sure you are checking AC voltage. Next check DC voltage at the power switch on the inbound side of the switch. The power switch is usually after the transformer and AC to DC circuit. If you are getting power to all three places, check the other side of the on/off button. This will eliminate most of the power-related circuit. Also, look for blown capacitors, or burned areas around the power circuit.

I have a panasonic tv it is a 2004 model pv-dm2794

@Goonnowthenn "wont light up... ..what have I zapped.." Hi G... As long as you didn't leave stray cables dangling around from the removed DVD, there should not be any short circuits. If you did, something may have touched where it shouldn't and shut down or blown the electronics. Another cause could be the self-protection firmware detects a fault, due to wrong amperage or an 'open circuit' condition. ie: The missing DVD module or part could be confusing the TV.

If you have no video and its making a popping noise its mostlikely shorted convergence circuits. Contact www.TvRepairKits.com and ask them to make you a kit for chirping sets.

What is the correct part number?

The recommendation of the manufacturer is to replace the ICs with the same part number. In this case, use hte STK 392-110. Some people "upgrade" to the STK 302-150 because it can handle more power. The added power handling will not significantly increase the time of the set at all. This is your call. Either IC will work as the pin-out is the same for both.

I'd use the original part number.

Vertical lines all over screen

Easy answer, most of the time verticl lines are due to dirty lenses and bulbs inside of the tv, This can be resolved 1 of two ways: either you can open the back of the tv and clean both the lenses and bulbs with a special lens cleaner or you can pay a tv repair man to do it they usually charge anywhere from $60.00- $150.00.
