Mitsubishi just got some bad capacitors and they end up running hot which cause them to bulge. If you are planning on doing the repair yourself I would suggest getting the service manual at the following link, as they will email it to you and they will also provide free tech support with an expert on that chassis and he will help you with the repair as special capacitors have to be installed and while your inside the set you should change any of the caps that are prone to failure. they know which ones they are and they can make the repair an easy one for you. Heres the link.

Can a drop cause a capacitor to bulge?


Not likely. Caps are likely bulging due to heat, and are near end of life. Even if you didn't drop it, it would fail when a cap failed altogether.

Tv turns on and off all by itself, all day long. picture is still perfect when it stays on long enough.


Good day..


That problem is usually cause of bad capacitors on the power supply section..

As you stated your TV works fine and after a minute the red light comes on...

That symptoms is cause of bad capacitors..Normally bad capacitors can check visually if the capacitors look like leak/bulged on the top that is the indication of bad one but not all bad capacitors are bulged some are not so in that case you have to used a special meter called capacitance meter..

This is the sample picture of bulged capacitors:

Power light becomes dim


I have discovered that this is a common problem with monitors and it is caused by capacitor failure. The capacitors in your monitor hold power enough for the display on your monitor. Inside your monitor, on the board where the power cable is connected, that is where you will find capacitors. Get any computer technician to open up your monitor and check for any bulged or burst capacitor. A malfunctioning capacitor will be identified with a bulged head or a burst. Remove the failed capacitor(s) and replace with the same type of capacitor(s) with the same voltage and degrees. Make sure that you note the polarity (-) and (+) when you are replacing the capacitors. This would help you out of your problems
