Some people I contacted said it has faulty capacitors that need to be relaced. Available at radio shack.
Most likely causes in order:

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


To replace capacitors:
  1. Keep yourself "grounded" when working with the circuit board. Static electricity will destroy electronic components.

  2. When replacing the Capacitors, press them "down" onto the circuit board as far as they will go, hold them down, solder into place and clip the excess terminal lengths flush with solder. Only by doing this will the metal shield (little silver box) slide down and over the circuit board during re-assembly. There is not a lot of clearance when doing this, as the 105C Capacitors are slightly longer that the originals. With minimal effort everything does fit back together.

  3. Use ONLY 105º C capacitors with a voltage rating of 35 V.

  4. Re-insert the DM circuit board into the Mother board; press virmly and ensure a proper seat of the DM board. Next, slide the metal case down and over the DM circuit board.

I have a 10 year old Sharp LC-46D62U flat screen tv. The power light continuously blinks green as soon as the power cord is plugged in. There is no video or audio.


TV set power supplies are subject to failure of large capacitors in the power supply which only have a shelf life of about 10 years so your power supply has likely failed. Unfortunately the cost of new TVs these days Baker's such that it's not worth repairing. And there is no simple fix that I know of. I have personally recycled hundreds of these TVs with the similar issues and indication. If you're really serious about it, you can look for a replacement power supply on eBay for the same model. If you have technical abilities than replacing the capacitors would likely fix the power supply. The capacitors are not very expensive but you need to have some technical skills. Any capacitor that has leakage or a raised top even a slight amount is likely bad. Jenna Lee for a repair we replace all the caps. Good luck

Check the capacitors and replace the power components. It is an easy fix if handy with soldering electronics. Tv Repairman may charge less than $100.00 bucks to fix it !
Good luck

My question is that my toshiba tv 37inch tv, stop working the tv went blank but the power light is still blinking with no picture. Light still blink green


It may be in safety down mode due to shorted circuits or failed power supply. I would start at the power supply section first by looking for any caps with domed/leaky tops, burnt components, etc.

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.
