    Actually, it was about 2 weeks ago.
    ===================================

    If that means lamp was replaced 2 weeks ago and then tv started no power up problem.
    I hope replacement lamp would be Panasonic original and if lamp was some low price after market then lamp can be cause of problem.
    One more problem occurs in this model is ballast supply that provide high voltage to lamp. Ballast supply board become defective and tv refuse to turn On. There is ballast repair kit available at Part Store that will fix its issue, repair kit contains few parts that will be replaced in ballast supply board and tv repairman is needed to do that.
    Thanks.

TV won't power on


Sounds like the bulb is not firing. I have the 44 inch model. Like it too. It is normal for the power indicator to blink for a minute or two AFTER the set has been turned off from running. get a phillips or panasonic TY-LA1000 bulb or a P22H 120 watt one if you can remove the old one from the housing (not very hard to do).

My Magnavox TV give sound but no picture. When I turn it on the light in the bottom right hand screen goes green, then flashes to yellow and goes back to green. The screen does not change it is constantly...


You need to replace your backlight inverter.

Check that all voltages are coming from the power supply as they should. The power supply will be stamped with the correct amounts, and you just read with the multimeter to confirm.

After those check out ok, you will need to replace the inverter to "light" your screen again.


You can hear sound because the tv is ON, but the inverter isn't lighting the screen!


Hope this helps, please rate!

Set was on and made a loud pop noise and the picture went off. the red light was flashing and no picture. then it made a strange buzzing type of sound a few times. turned off for a couple mins and then...


It sounds like your screen inverter has just gone >bang< unfortunately.
Most screens inside use 2 main circuit boards, and you are most likely going to have to change one of them.
It's possible also for it to have been just the backlight bulb making the loud pop noise too. The inverter may have given out too much power and blown the bulb (a lot like you hear when a house bulb goes bang).

If you can't actually hear any TV sounds (normal sounds like music, voices etc. when they should be there), then it means the problem is more serious, and would need a specialist repair place to check out the electrical circuit inside.
