It sounds like it could be your main board. Over the years the board's connections could become loose or the board itself can be going bad. I would call an expert maybe someone from an online shop like rivervalleyelectronics.net can get you a board for cheap since alot of these older model TVs parts are not carried by the manufacturer.

3 LEDs in the front blinking.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

SOURCE: no pic...humming noice on 62'' toshiba dlp

was the lamp blown if it was blown you could be hearing the ballast
if the lamp was not blown and the new one did not fix it the red light indicates the door there is a little switch when you put the door back on if you look at it it may need to be adjusted so it will connect with the door if that is not it you could have a fan that is not turn if it is making a real loud constant humming noise while it trying to fire the lamp you probably have a bad color wheel

The squeeking sound could be the high voltage trying to strike the lamp, it will try several times to strike the lamp then shutd down. Take the bulb out and see if it s blown. Even if it is not blowen it sounds like you have a bad bulb.

Mitsubishi WD -60737 60" TV how can you check anything with no pic or sound


Bradley,
Can you power on the TV with a remote control or does it shut back off? When you hit the power button does it make a click noise attempting to come on and then shut off? Does the lamp light in the front blink?

I would check the lamp. I recommend Discount-Merchant for the replacement lamp... be careful buying from Amazon or eBay type marketplaces as they are infested with low quality generics!

Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.
