    110% satisfied. I received the part today, put it in and tv is working fine. Sears had part in stock. Best $11 dollars I've spent in a long time.

The power board has been manufactured by Proview, and is used on Memorex, Polaroid, and Bush TVs
Here is part from Sears for $45: Pcb, power-only .
The original part had been discontinued , and it is difficultly available. It has been replaced by part PROVIEW IPOS 150 REV:1.8 200-P00-HM150H (RRP $170).

In case the original PWB is not available from Sears parts , then you will need to buy the more expensive compatible replacement . Here is the part for $114.
Please do not forget to accept the solution afterward.
Thanks.

Mlt3221 screen went blank, with a bit of smoke at the back of the TV, then there was no video, just audio.


Check the power supply for bad or bulged electrolytic caps , or replace power supply board.

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.

32 in, LCD will turn on, sound but no picture. It was playing and just faded out, can't get the set up screens or any thing. When turned on it acts like it will come on for about 5 sec, picture starts to...


0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

More specifically on #1 and #2 - capacitors either bulging, leaking, or exploded.

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

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.

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!
