My tv made a loud popping sound. Now the bottom right 1/4 o the screen is black with different colored lines on it


Check for any bursted electrolytic capacitors on its main power supply regulator board. The sound you heard might be to this burst. Take care, and unplug the TV from AC mains supply wall socket, before opening and checking this board. See examples of bulged [bursted] capacitor.

I have 60 inch mitsubishi hd DLP flat panel projection screen model is wb60735.i unplugged it from the wall then i plugged it back in the wall the next day.it came on but the screen was all black but still...


If you see absolutely nothing on the screen then you may have a problem with the Lamp unit. If you can see around the back of the TV look to see if there is a vented opening with a noise of a fan and a rather bright light. If you see there is no light then try a reset (hold power button for at least 10 seconds). Turn the TV back on and the green LED should flash for a bit. If you still have no picture or video of any type (completely black screen) and have sound only you probably have a bad lamp. These lamps are around $125 or so and can be bought on Amazon or other sites that sell these parts. It's fairly simple to replace but make sure that the tv is unplugged and securely re-install the access door. Hope this helped.

Screen goes black tv stays on. Turn off and on and TV's fine.


I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

Possible problems: * The TV set may be unplugged. * A fuse or circuit breaker may be blown or switched off. * The remote control unit (RCU) may be disabled. Solutions: * Make sure the TV/VCR are plugged in and the wall switch is on. * Check the fuse or circuit breaker. Test the outlet with a lamp. * Replace the RCU's batteries: if this fails exchange the unit.
