Picture went out on p50hdm Vizio Plazma tv after loud POP

You may have found the source of the loud bang. Time to turn it over to a repair technician.

The power amplifier chip (which goes "pop" when it goes bad) may be located on the board where the IR sensor is. Sometimes (but not always) you can make the TV come on by holding the power button in _until_ the TV comes on. But that usually only works when the chip is "going" bad. If you heard the pop, it's probably shot. Also, check for a fuse on _any_ of the boards, and possibly a main fuse at the back of the TV.

Check and replace damaged component/s at it main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts. Do asearch by type in the brand name of your device at its search box.

It will be best to replace the power supply regulator board as card basis.

P50HDM, loud pop then no pic...

Ur backlight video inverter board is dead.Buy parts like capacitors for replacement with soldering or buy the whole board.Tries these websites.Shopjimmy.com,Partstore.com or Ebay.com.

Hi there! This could be as a result of several boards. Y-sus, Z-Sus or power supply. One would need to check that all the relevant Voltages on the power supply are actually present. Next would be to check the Fuses on either Y or Z-Sus boards. The board with the fuse blown would most likely be the one at fault. However it blows for a reason so replacing the fuse on these boards will probably not help. But it is worth a shot. If all else fails refer to a repairer. If you can get the boards and want to try doing it yourself it may or may not prove to be successful. Please beware of HIGH CURRENT before you proceed. Best Wishes and Good Luck, JUS004

approximately $575

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.

That problem is the Ysus board, Sometimes people will replace the Zboard at the same time. If you bought it at costco a couple of years ago you are in luck costco will refund your purchase price, costco has changed the return policy and newer tv's are not refunded, but something to look into

ours was off all day and it pop 2 times and now no picture at all.
