    if your looking on the board itself youll see a lj92-???? or LJ41-???? number. this number will also help me with part number

    what is the tv model number

  • Anonymous Oct 17, 2007

    perfect thats what i need to know. send me your email addy to [email protected] and i will email you a manual that will be great help to you. your tv is the same as s50hw-xd03 in this manual. the only way to know for sure your power supply is bad iss to check the vs and va voltages. the large board in the top middle is the smps( also known as power supply). you will see a wire harness with one black wire and the rest white going to a board on the left side. check to see if you have your vs and va voltages heare. if they are there you will need to replace the y sustain board. if you dont have them then you will need to replace the smps. the manual i am going to email you has all the part numbers

It is repairable (or should be). It's not something you can do on your own, though. Parts will need to be ordered and replaced. Any repair shop should be able to get you up and running again. Call around for estimates.

50" Insignia plasma made a pop sound

I heard a pop. The TV went off then when I turned it back on the white has red pixels showing. Seems one of the LCD colors went out. Is there a fix. The TV is jsut over a year old.

This is a plasma tv not lcd. The pop mostlikely was a part on the y main board. IF the y-main voltage shifts the set will have red sparkels.

I have a 50 inch plasma vizio tv. I was watching it then i heard a pop the screen went black and i still had sounds yesterday but today no sound, I called vizio tech support they told me it was the gas...

when you here a loud pop its usually the sustainer boards. Have you checked the fuses on the sustainer boards first to see if they are still good. There is a IC chip under the heatsink and when it gets extremely hot it gives. Also check you power supply board to make sure you don't see any swollen capacitors, leaky or bulged out from the top. Let me know if that helps at all.

We have a pioneer plasma tv and there was a loud popping sound and then the screen went blank

I had the same thing happen a few weeks ago to my zenith 50" plasma tv. I tried to turn it back on with the remote and the power button on the set but the only thing that happened was the led would flash green 3 times and then go back to red. I took it to a repair shop and they called yesterday to tell me it was going to cost $700 to fix it by replacing the power supply. No guarantees either that it will last any longer than the 3 years I've had it for either. But it's still cheaper than replacing it with a new "bigger" tv which is what I will eventually do anyway. I've heard of people looking on ebay for repair parts and doing the repairs themselves but there is no warranty on human error...

LG 50inch Plasma received loud sound then went black

I suggest you guys take your TV's into a repair shop like Sears or Best Buy... The main reason most plasmas go dark is because of decay, but I don't think this is the case. Because what you describe is similar to what happens in LCD's when their back light goes out. Although you can open up and repair the back light your self in a LCD, I would not advise you to do so for a Plasma, because of the hazardous chemicals used in the plasma display plus the fact that plasmas don't use back lighting. And 2 years is way to soon for decay to be a factor. So more than likely a circuit shorted out and the TV has to be opened up to be repaired.

LG 50" plasma tv

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.
