Mitsubishi dlp rear projection no picture with sound

    tv powers on and makes 3 humming like noises, sounds like its spooling up if that makes sense not sure if thats what was meant by "sparks", then she just powers off. I've tried to get the error codes and i get 12 when she's powered on for those 2 mins and when the power is off it gives me 66 which i think i found means no lamp detected / my board is just not picking up my lamp? either way the lamp is not getting power and I have no picture. I really like this tv -when its working- but I've been thru what appears to be my second lamp now and had service reps out here to replace some sensor. Its really frustrating I hope some one can help.

    thanks in advance

    I also have the Mitsubishi WD-52631 and it is behaving the same way. I've been

    Unplugging for 2 minutes

    Plugging in direct to AC outlet

    Depressing the reset button on the front

    Waiting for the blinking green light to stop

    Powering back on

    The TV tries about 3 ties to cycle power on but all I get is sound - no picture at all. The TV is just under a year old -

    Should I replace the bulb and light assembly or just the bulb ?

    I've read of air flow problems ? Anyone else ?

Okay so yeah, i had replaced the bulb too, and that did fix everything for about two months, but alas this darn thing burnt through that bulb too. so now we've had some repair guys come out and said that their gonna replace the ballast(sp?). The guy told me he's had to do it a few times for this model tv and that he hasnt had to come back to fix one yet so i got my fingers crossed that it'll finally work.Luckily it was all covered under my warranty. I'm not sure what replacing this actual part entails, how much it costs or even if its something you can do on your own. The worst part is my wife and i really like this tv so it stinks we've been haveing sooo many problems. I've already had one thing replaced b/c of the fan and burnt through three bulbs in less then two years. Good Luck everybody

I had the same problem with mine as far as coming on then shutting back off and blinking. Troubleshooting states to replace light cartridge. I just replaced the bulb itself and saved about $150. Now I am having other issues but that fixed that problem.

Severl things could be wrong, first is the lamp attpting to start, this you can usaly hear it will sound like little sparks and happen tree times before the set shuts down. If thats the case change the Lamp, second the five volt line could be dead, this is cause by defective capacitors in the power supply and this prvents the DMD board from comming up, with this problem you will not here the lamp trying to fire. Third it may have detected some other fault and shuts the set down, These sets by the way the status light in front blink can direct you to the problem, so unplug for 10 min. then try to turn it on Write down what the L.E.D's do and repost here

Mitsubishi WD-73286 is DLP tv that does not have any convergence circuit inside.
Convergence is required in old model rear projection tv that has three basic colors picture tubes to generate color picture that projected on front screen of tv.

No display or sound on Mitsubishi WD-52725

This is a DLP They have issues with the color wheel, the winding sound could be from this color wheel. If it stops spinning it will cause the tv to shut down. DLP is a mechanical display process. If you are handy and understand electronics you could replace this yourself. If not i would let a tech handle it.

Mitsubishi dlp 52525 garbled rolling picture. Picture just colored lines, rolling slowly. Sound fine, fairly new lamp.

You most likely have defective capacitors in your electrical chassis. It's best to send the entire chassis back to the manufacturer for total rebuilding. The cost is about $350 + labor, unless you can remove the chassis yourself.
Good luck.
