Question about Mitsubishi WD-52627 52" Television
The problem I am having now is, periodically, when the tv is turned on, a buzzing/crackling type of sound comes from the back of the tv and the lamp will fail to light up. Sound will be fine and the tv will shut down after a minute of no picture. Sometimes when the lamp fails to come on after the buzz, hitting the on button again will bring on the picture (no buzz). This is completely random. I have looked behind the tv when the buzz sound is present and I can see a light (not a spark but flickers with the buzz) from inside the vents up and to the right of where the lamp housing is. Thanks for your help, let me know if you have any other questions
If your looking through the vent at the backside of your lamp cartridge if the sparks are coming from the right side thats where your ballast circuitry is on that small circuit board the wires may not be properly connected or you may need a new ballast let me know if I can help you any further but before you go any further since its a hard chassis to get apart you may want to consider getting a service manual if you do just post me a model number and I can supply a link for you and they also give free online tech support with the manuals
