Yes, he means 2200 microfarret (called uf from here on out). Another important concern when buying a replacement is the voltage. You need to get something that is at least 25v. I recommend a 35v or better. Another notable point is that this may not always fix the problem. As with mine, there was also a 1200uf (microfarret) 35v capacitor that was blown. You can tell this because they bulge at the top. I have both of these caps (2200uf 35v and 1200uf 35v) on order and they will be here tomorrow. If I do not post back here then they fixed the issue for me. I suspect that this will resolve the problem. Look for bulges on top of the caps. This is an indication that they are blown. Most all of you experiancing these symptoms will see the 2200uf cap bulging but you may also see others bulging too. If you do then you need to replace those too. No electrolitic capacitor should be bulging at the top so if its bulging its bad, and if its bad then your tv will definitely not work. Have fun.

SOURCE: Power light on but no picture

I've got the same problem. No sound, no picture, just a green light. The light comes on when its plugged back in. No buttons work. Occasionally the light flashes off.

This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

My magnavox tv model num 50mf231d137 will not turn on it turns on then turns off with red light blinking


How many times this standby/power light blinks at one time switch ON? Count it carefully. 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 google.com/+GopakumarGopalan

My magnavox hdtv won't turn on no green or red light on the power butten no power at all


Start with the obvious. Is your TV plugged in? If it is on a power strip, does the strip need reset? If all is normal there, then unplug the set and take the back off. Check your fuse to see if it is blown.

65" mitsubishi rear projection tv won't turn


IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.

Magnavox tv when the power button is pressed the green light comes on but nothing else happens; there's no picture or sound or nothing; but the green light simply stays lit (no blinking).


Hello,

first, press the channel -/+ button on the TV. If that doesn't turn on the TV, then it means you have to replace the bulb of your TV. The bulb is most likely dead.

Replace the bulb and your TV should be restored.

Let me know if you need further assistance.

Regards.

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.

I can't get my tv to turn on... nothing but blinking red light


Dont know if this will work for you or not, but my brother gave me his because of the same problem. It would power up and a green light would come on, then after 10 -15 seconds it would change to a red blinking light. I plugged a usb cable into the service port on the side and left the other end unplugged. Then plugged the tv back into the power. i took a small screwdriver and ran across the contacts in the end of the usb cable until both the red light and the green lights came on. I did this several times listening fot the clicking noises in the TV. after doing this for approx 20 seconds, i pressed the power button and the TV worked fine. 5 days now and no problems. Only thing I can think is I somehow reset the software and now it is working fine. Hope some of you can figure this out and give it a try. if the TV is just sitting, you have nothing to lose
