You most likely have some faulty capacitors on the power module. You can easily identify a bust capacitor. They will have swollen tops. Here is a sample pic:

Check the specifications of the faulty capacitors, and getthe replacements from your local electronics shop. If you are comfortable withthis, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out thedefunct capacitors. Once that is done, solder in the new capacitors carefully. Ifare unsure how to do this, try to get a friend who knows this kinda stuff to doit for you, or get a qualified technician.
Warning: If you do not have a background inelectronics repair, or are inexperienced, get a qualified technician to do itfor you.

REMEMBER there are very dangerous voltages inside a TVthat can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECTTHE POWER BEFORE YOU DO ANYTHING.

If you want to go in for a long term solution, youcan easily replace the whole power board. You can get spare from HERE.
They also offer FREE online technical advice as you do the DIY..



Hope that helps!

Your main boards are bad. They are no longer available, You have to have the chasis rebuilt. Mitsubishi is rebuilding these chasis. You have to pull it without any cut wires & ship to Georgia.

SOURCE: Mitsubishi WD-82738 has no picture,

After rereading the symptoms you descibe what you describe might be a faulty colorwheel. When the set is first plug up there is a small mechanal motor that has to reach certain speed. if this does not reach that speed the set will not allow the lamp to fire. The whirring sound could be the colorwheel trying to spin up. these break all the time. (its a motor and anything that moves eventally will not.) it a fairly simple rep;air thatn most quilfied techs can repair. Such a repair generally should take more than a hour to do

These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/ Blinking code detail, and fault finding procedure to many brand TVs are given.

Mitsubishi tv wd-82738 no power


Most of these TV's have switched mode power supllies that run very hot. There is a likely chance that the capacitors have cooked (burst) on the PSU board. They are common capacitors. Open up the TV and with the mains electricity turned off, check the 'X' on top of the tubular capacitors. If they are bulging, rather than flat, then unsolder them and replace them.

I've repaired many of these sets because of this problem.
