WD65638 Mitsubishi TV. Picture wouldn't show at all so we knew it was the lamp. We have a pic now . Just replaced the lamp and it worked! 3 hours later the color started to fade and turn purple and green. We hear a faint noise. We turn it off and wait a bit. When we turn it back on the color is great again and noise is gone. We watch for about 20 to 30 minutes and it starts all over again.

SOURCE: Shutting off and on...

the problem may be due to dry soldering in the power supply stage if it was with the lamp there would be red or green light showing the presence of the power to the tv after making it own some of the components get hot and it will make the the soldering point conectionless and after some time the heat sink get cooled and the soldering point gets connected and u will see the picture again it is a simple problem if u have a soldering iron u make it hot and re solder all the components in the first part of the circuit board and the problem if rectified

SOURCE: Replaced lamp Mitsubishi WD-52531 worked for one day

Ballast Board may be Bad it is what turn Lamp on Call Encompass for parts 1-800-638-3328 or look for one on E-Bay they have good deals on Parts.Also CK Fan to Lamp it maybe defective .Call Mats for Fan 1-800-628-1118 they have lamps also.

hi,
As you have mensioned there is problem with the LOT (line out put transforme also called flyback transofrmer) and also the driver transistor fro it . The noise heared is from this transformer. After some years of use its insulation strenagth will become weak. As it is a high voltage step up transformer the this voltage will discharge to the nearest ground point becuse of the weak insulation. This discharge will make a noise like zzzz. You have to replace the flyback transformer along with the driver transistor. When the flyback discharge to the nearest ground this will consume more current. This will couse in the failure of the driver transistor. After that the tv will not switch ON . You can get it from the nearest electronic spare part shope. replcing the flyback is a skilled job because you have to desolder all its leags very care fully. The part number for the flyback transofmer can find on the specifiction sticker sitked on it. Its nubmber is 259296. If you are not well in electronics try to cosult some one near you to do the same. Have added the picture of flyback transformer. the component in the red circle is the flyback.
OK
