I have a Mitsubishi TV model WD-65C9 and yesterday I heard a pop sound and the screen went black but there is still sound. Is this just a lamp bulb issue?


That pop noise was a so called "CAP" capacitor letting (they actually blow up) go on a circuit board, open the TV cabinet up and look carefully for a burned spot on the circuit boards, it will be small, when you locate that board it may fix the TV is you replace the damaged board.

Red light blinking


When it popped something went, you likely will not see it as this usually is a part that is covered with a metal heatsink, that aside either open it and look for signs on the power board including puffy caps or if not able to safely do that get an estimate here.


not really any way around this, someone has to at least look and then use test equipment to see if voltages etc exist---the nature of these sets (all brands) is they only sell the circuit boards.

Hi,Iwas watching TV and the screen went black.No lights on,I unplugged and plugged again but anything happened. My TV is a Toshiba Regza model 42RV530U. Can you help me? Thanks


If there was a popping noise of any kind when the tv screen went black there's a high possibility that one of the fuses in the tv popped and there is no power to the tv. It could also just be the outlet itself and try plugging the tv to different working outlets.

Heard a loud Popping/snapping sound, and the screen went black. The unit still has power and audio but no picture at all. I looked at all the capacitors and they appear to be in good shape. 75$ just to...


Hi,
Possibly ZSUS or YSUS boards are gone for this kind of problem, please check at shopjimmy.com for required boards and new lcd tv is rather better than repairing this plasma tv.
Thanks.

I have a 42" legend tv with power supply board 667-ps42d8-20, all capacitors look good but i know one or more are shot. Have you ever dealt with this tv and power supply


I just inherited the same tv from my girlfriends parents. They say they heard a loud pop and the screen went black. When I turn the tv on I hear a strange noise coming from the power supply board. It sounds like it is coming from one of the yellow capacitors (sorry if there not capacitors new to tinkering). I have read that it could be the y sus board but I feel like its the power supply board. If you have found any solutions please help me out. Thanks

47LG70 - PICTURE WENT OUT. STILL HAVE SOUND. HEARD A POPPING NOISE WHEN PICTURE WENT. TV IS ONLY 1 1/2 YEARS OLD. ANY IDEAS WHAT MAY OF HAPPENED.


I have had the same problem off and on with my 47LG70 for months. When the "popping" noise happens, the blue light in the corner stays on, so I know the tv is still on (sometimes I still have sound, sometimes I don't). Sometimes the screen goes black, but other times it is blue. If I turn the tv off then on again, it might stay on for seconds, minutes or hours. It's been very frustrating.

This seemed to happen right after I got my new Comcast box, which came with an HDMI 1.3 cable. I read somewhere online that this tv might not be compatible with that cable, so I unplugged it and am using component cables again. I just did this today, so I don't know if it will work, but so far the tv has been on for 30 minutes with no problems.

I'm pretty ignorant about HDMI compared to component cables. I imagine I will not get as good a picture with the component cables, but I am willing to sacrifice quality if I can just get the darn thing to work. Mine is also only 18 months old.

Hope this helps. If it doesn't, maybe someone else out there can help us both.
