Did you let the green light flash for about 70 seconds? It goes thru a self check when plugged in and takes a little time

Did you check the caps on the power board when you had it out?

YES

One of two possible issues:1. Lamp is nearing end of life and may dim just before total failure.2. A few of these models have 2 mirrors(check with Mitsubishi to see if yours is one) A large mirror in back (never gives a problem and do not try to clean it. Some idiot in these sets used a small mirror inside that the optical unit shines the picture into (wedge shaped mirror and small) and it is facing up----the fans intake air from the front of the set around this mirror--it gets coated with lots of dust---Picture can loose up to 70% of its brightness and clarity if that mirror is dirty--looks like 20 year old set .If you do not wish to check with Mitsubishi GOOGLE THE MODEL NUMBER with "mirrors" to see.If it has 2 mirrors I can tell you exactly how to get at it.SD TECH

I have a blinking yellow light and tv won't turn on

Is this a DLP or LCD projector?

You have to remove the lower panel on the back of your tv, then remove the light engine. Unhook the wires attached to the DMD board. Remove the DMD board. Remove the heat cink from the DMD board. remove the optical lens but don't touch the lens. There is a video on shopjimmy.com that shows the entire procedure. Takes 2 hours. The optical lens can be cleaned with an eyeglass cloth, same for the DLP chip lens. no wet solutions on lenses. Remove dust from other internal parts with compressed air in a can. Your picture will be clean and clear. Wear latex gloves and make sure you are grounded to prevent static electricity.

There are a number of reasons this could happen and unfortunately not much that you can solve. If you have a backlight control in the menu you could try turning this down to see if the problem is reduced or cleared. This won't help you but the info may help a tech.

Hi
Have you tuned the channel frequency tuner? Use the remote to bring up setup menu on TV, scan channel frequencies & save. If it's an old TV that can't pick up digital signals, then you need to get a digital set top box & tune to TV.

Suspect the bulb/lamp has failed. If you didn't get the factory replacement the cheap ones sometimes only last or a few weeks, unfortunately.

Chances are you have something wrong in the main board..replace it and things should be back to normal or try a hard reset

pop sound i would think a main capacitor has gone, on the power board. it could be just the capacitor or the voltage regulator has gone as well and blown the capacitor. it could also be the diode that has for pins has + & - on it with 2 squiggly lines on it when this goes it can go with a bang and there will be no power light or anting, and it also blows the 5 volt side of the tv. so all the parts would need replacing.

bad lamp

The part to fix that is about 300 dollars.
