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 not able to locate the component than has 4 switches to turn on. Any assistance will be greatly appreciated. Not tech savvy so extreme laymens terms would be great.

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.

Tv turns off by itself


This may be a case of something overheating inside the set---check to make sure airflow is not restricted or blocked---set in enclosed area where it cannot cool.

My tv turns on, but gets no picture. It occasionally flashes the display, but quickly goes blank.


Hello The problem of your television is no picture.Usually in that symptom of LCD TV the problem is no back light.If there is no back lights the screen or display is totaly black.The problem is in the back light driver board, maybe there's a blown mounted fuse in the driver board or bad or leak capacitor from the supply of the back light driver board.Thanks...Hope it will help you to fix it..

Memorex mlt3221. white screen, no sound, no function.


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

My Sanyo DP46848 LCD TV display goes black when turned on.


My mother's was doing the same thing (purchased 2008). Put up with it about 6 months and took it to a repair shop. Bottom line - the display panel has a flaw in and will cost more to replace than the tv cost. See about it now it yours is still under warranty.

No picture on Memorex MLTD3222 flat panel LCD.


I recently got this tv from somone because of this exact problem. I have found a solution that works for mine. You can check to see if it works for you also. What I did was take of the back cover. 3 screws (1 big one in the center and 2 little ones below it). Next look at the power board. If plugged in and turned on the red light on the power board should be lit up. If so your power board is fine. Next find the component that has 4 switches. I manually turned these on and turned the tv on and it worked! Has been working ever since!

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.
