Check the power supply module for bad DC filter caps first, then check the backlight inverter board for shorts.

Sound but no picture, can change channels, red flashing light on power supply board. Please help.


The problem is likely with the screen itself. The power supply usually supplies both screen and speakers and has a light flashing on it indicating that it has power. Screens are often not worth replacing unless under warranty as they can sometimes cost as much as new TV to replace.

The LCD Memorex model MLT3221 turn off the display with no reason the sound remains work properly


If the screen has gone off but the sound still works then its most likely the inverter has gone bad. Check for open fuses or leaking and expanded capacitors.

Problem with the Memorex MLT3221 32 in. LCD TV. When i turn on my TV it displays "Memorex" and very quickly, then it goes black. I took the back off and the red light is on on the power board. But, I am...


I would actually not recommend opening the TV since you could get an electrical shock. I can suggest you to unplug the TV for a while (30 minutes) and then just plug it back in and turn it on. If that does not work, my recommendation for you is to take the TV to a local repair shop. It may be a fuse or internal component shorted out, but in this case is better to have a technician check the unit.

Can i get a screen for memorex model# mlt3221 32'' LCD tv the screen is shattered! please let me know


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!

Memorex 32' lcd tv shut off


Hi!

It sounds like you have a power supply problem! You will probably find some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain). As far as the noise problem this could be caused by harmonics, from the bad caps!

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.
Let me know your findings and we can proceed from there.
