Power supply in most cases and a lot of the time the part is under a heat sink where you cannot see it.

You might have more help if you posted the question again with the exact brand and model number.......

SOURCE: Loud pop Blank screen 42 inch Viore Plasma

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

SOURCE: Pop sound then no picture, just sound

I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

SOURCE: I have a Vizio VX37l and was watching it and then

It sounds like the 5vdc standby circuit is still working, that is why the main fuse is still good but you may have bad 24vdc power supply, look real close again for blown transistors or IC on the power supply board, but it can also be the backlight inverter circuit boards that blew up also. Look here to see what good parts look like: http://www.shopjimmy.com/catalogsearch/result/?q=Vizio+VX37L+
Please post back what you find.

I have a Vizio p50hdm while watching heard a pop noise and tv went out cant turn back on.I replaced main board and power board and still doesn't come on any Ideas?


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.

Sounds like a warranty job - pop noises are electrical shorts - Possibly the power supply unit.

I was watching my Hitachi 42hdm12 and heard a pop and now the picture won't show up or sound or anything?


A pop is usually a power surge and you blew a board. If you take the tv apart, if this is it, it will be evident by the burn marks. You could have burned out the internal power supply as well.

Panasonic Viera tc-p65s2 - 7 blinks, won't turn on


I had the same problem with my Viera. if you disconnect the power and ribbon cable from the YSUS board (check youtube for how), the light led will blink 6 times, indicating the YSUS is bad. Check ebay for TNPA5175 board (about $115-160). The pop is one of the DG402RP chips burnout. These are about $4, but only available from China. If you can wait a month for delivery, you can solder the new one to replace the bad one. You may want to purchase several in case more are bad or it happens again.

Heard pop an my panasonic tv shut off. can't get it to turn on again


Power supply is suspect number one---in most cases there will be a for example 10 blink code from the power light---damage to the board may be hidden from view--so even if looked at you will see nothing.

Hitachi clu-4591av stopped working - popping sound


The power supply regulator section should be troubleshooted. The "Pop" sound you heard might be of a bursted electrolytic capacitor in the AC mains rectifier section inside the TV. All the related commponets, rectifier diodes, protection zener diodes etc:- should be checked before switch ON the TV further.

We have a toshiba 72 dlp tv. We were in the living room in which tv is in we heard a pop. When we went to turn the tv on we heard sound but no picture and the yellow light on the front of the tv blinks 16...


Good day!!!


Your color wheel is clapped out. The part is not directly replaceable - they seal it in the light engine and won't sell spares. A rebuilt engine for this set will probably run you between 230 and 270 USD. Replacing it is a cinch if you can get another engine for it.
