Memorex MLT3221 32" lcd tv: No Power Indicator

SOURCE: Can not access menu or input functions

Hi rduncan27,
I will be happy to help. 88% of LCD tv problems are with the backlight, the symptoms you described indicate a probable inverter malfunction. Lets do a simple test to check the functionality.

1. Get the tv to a point that it is producing sound.
2. Take a flashlight and shine it on the screen.
3. Look very closely for a dark video image.

SOURCE: can i get a screen for memorex model# mlt3221

Even If you could, and you can't it would be directly threw memorex. You can go to there website, look for the support section and email them asking. Chances are if they will sell you JUST a screen it will be pretty expensive and as far as installing it that would be an entirely different situation. Sorry your screen broke and this probably isnt the news you want to hear.

Thanks for stopping by Fixya!

SOURCE: TV will not turn on. Went dead shortly after turning on can't get it to turn on again. Seems like it is not getting AC. Yes its plugged in and there is juice to the socket.

If the red ring in front of tv is not lit when it is plugged in it is probably the power pcb. I just ordered one from searspartsdirect.com part # 860-AZO-IPOS150H FOR $45 plus shipping. installed today and everything is fine.

Solution..... The unit ONLY accepts digital TV input. Typical cable input is NOT digital. If you want to run cable into the TV, you must treat it as auxiliary input, meaning you have to connect it through a cable box, just like the input was from a VCR. You then control the TV channels from the cable box, not the TV itself.

You can typically sign up for digital cable for an extra fee, just like for any other HDTV.

I wish I could give you a better answer but this is the only way we got ours to work as we do not have HDTV service on our cable yet.

IF the Standby Red Light does not come on when you plug in the TV:


1) Check fuse on back panel next to power cord. Pull out cord and pop fuse holder out. On an ohmmeter, it should read 0(short)-that is a good fuse.

2) Check the fuse on power supply board next to power connector. It is soldered onto board.

3) Be careful with this step: With all boards screwed in place, plug in TV and then unplug it. Next take a Voltmeter set on 200 Volts and test large electrolytic cap in middle of board-should have @100-200 volts on it. Do not short the capacitor-big fireball flash explosion if you do!

If 1-3 test OK, then:

D10 is shorted. HER304 in middle of Power supply board near large electrolytic cap. Replace with same diode or Radio Shack 276-1144 3A 400PIV Diode. PLEASE BE CAREFUL WITH HIGH VOLTAGE PRESENT ON POWER SUPPLY BOARD. UNPLUG POWER CORD!!! OBSERVE PROPER POLARITY WHEN REPLACING DIODE-LOOK WHERE THE BAND IS.
