Question about Mitsubishi WT-46805 46" Rear Projection Television

1 Answer

The green fades in and out

When i turn the TV on 90% of the time the green is out and then suddenly we will get flashes of green to come into the screen or it will turn the TV bright green suddenly. We were tol by some one to take off the front screen and look for dust on the bulbs. How would we be able to take off the screen and see?

Its most likely caused by a bad solder joint on the Green CRT dive board which is located on the bootom of the green CRT ( Center CRT) which you can accesss by removing the front speaker panel then the small access pane behind the speaker panel. If the solder appears good the green CRT itself is most likely defective.

I have a Mitsubishi WD-62525 HDTV that suddenly wont turn on. Just has a green blinking light when you hit the power button. Any ideas?


I found this on another website, most likely it is your power supply capacitors.
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.

  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.

  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.

  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

Suddenly turned off without warning Sony KDS-50A2000


Hello,

All you need is to open the back cover of the television and check on for dry soldering at the power stage of the printed circuit board, also check for bulged capacitors, if found replace with same rating of voltages , but if otherwise Ur power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get ur tv power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hope this helout, Good luck....

Power flashes green then turns red; Lamp flashes red.


is this a flat screen first off
if it is 90% of the time the vid card has over heated they have a video card kinda like pc's one thing is most companies dont put fans on them so they over heat especially when dust start collecting on it wait and see if anyone else has any thoughts on this but im pretty sure thats it you will need to take it to someone that works on tvs to replace it and also ask them if they will install a fan on it
but like i said wait and see if anyone esle has any thoughts on this first

RCA TV


This is a common problem and a local repair place shouldnt charge more then 90 to 125 bucks to repair. Its the tuner and tuner sheilds that need to be resoldered. Theres even an RCA service bulletin about this repair. At one time RCA was giving out rebate coupons if you had this repair done for future purchaces of RCA products but Im not sure if they still do this . Good Luck
