    My Hitachi 51UWX20B turns on by itself also. It can be turned off in the evening and 1 or 2 times a week it will be on the next morning. Its been doing this for several years. I'm just used to it.

    Yes relays are sticking . power light will stay on some times ,but picture goes out with remote . Some times both go off. wake up in middle of night and TV will be on . IR sensor is working because all controls work with remote, except the power will not stay off. Im looking for a repair kit and if any service bulletin issued by Hitachi for this problem .

    or it just may need new solder

  • jason May 11, 2010

    are you sure that they are sticking? because it wouldn't shut off if it were stuck

    are you sure its not the IR sensor? or the crystal?

It probably just needs some soldering then , when we get these in most of the time it needs new solder because after the set has been running the set heats up thus causing the solder joints to crack and not connect well , and the problem only gets worse as more components solder connection also start to crack and not make very good contact , this usually happens in the tuner solder joints and other components that create heat , so it will need to be looked at to find the bad solder . rca gave us a kit to fix some of the problems that happened , and it was a better solder with a paste that made a better hold on the heated components and connections
hope this helps

    also if you move the tuner a little bit and the tv shuts off then there is a bad conection there , but otherwise lleaving it plugged in like that condition will make something else burn out and cause more problems , it should get a resolder imediately!

    hope this helps

    also there could be a Short circuit on 24v line

  • jason Oct 24, 2008

    also change all electrolitic capacitors on the power oscillator circut and check them all over the board , check zener diodes( regulators)also

Mitsubishi tv model ws-65315, when i turn the set on, the green light comes on for a second then the set turns off what could it be


If the DM Board it bad you can fix it yourself.

There is a guide with pictures to help you.

It is easily fixable for about $10 worth of capacitors

Or a whole kit with all tools needed for $36

http://servicemanuals.vstore.ca/product_info.php/pName/v21v19-mitsubishi-dm-repair-kit/cName/repair-kits

That is an extremely common problem with Mitsubishi tvs old and new. It can be fixed easily and cheaply for those willing to use their hands.

Refer to this guide to replace the capacitors on your DM Power Circuit Board part # 935C9860. You could also have someone else do it for you for $100

Guide for a $10 DIY repair in capacitors : http://hdtvoice.com/voice/showthread.php?t=32186

Paid Rebuild Service: http://shop.ebay.com/?_from=R40&_trksid=m570&_nkw=PWB-PM-ASSY+REBUILD+SERVICE

That fixes the problem most of the time.

After replacing capacitors is you still get green light try replacing the EEprom. EEprom board also known as the E2P board is part number 935C978001
