Question about Memorex MLT3221 32 in. LCD TV
Turn tv on, it displays "Memorex" very quickly, then goes black. No buttons on remote nor TV work except power. I have the MLTD3222 which is same except DVD player on side. I can not change input because nothing displays when I push it. I had my cable box hooked up with HDMI, speakers turned off as sound was going optic output to receiver...I got sound but no picture. So I tried component, composite, etc. but nothing worked because I can not get TV to display input function to change input source. I have unplugged the TV and all that to try and get it back to out-of-the box settings, but it just displays Memorex real fast and that is it.\
After trying all kinds of input configurations, I finally got video two input to give me sound. Nothing gives me a picture. Video two (back panel) is the third input source from input menu per manual. I do not know why it is on that one. oringinally I had it as HMDI 2 when problem started (11th input source on menu).
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!

I am having the same problem... never happened before and I've had the TV for about 2 years. I tried unplugging it for about an hour and plugging back in, but not working. Will try it overnight and see what happens.... *sigh*

JADEHE'S Solution #2 was the correct fix...I would caution though that if you have limited mechanical abilities approach this with caution. There are many electrical transisters/diodes items exposed when you open the back covers of the TV so becareful not to damage them, but yes this was the fix. My thought is that this unit is very sensitive to power surges/lightning storms and these switches kick off ifon is sensed. Maybe a surge supressor at the outlet may prevent it from happening again, but those are just my thoughts based only my experience with electronics (which aint much)
Unfortunetly, I had already spent the $50.00 diagnostic fee at the TV Repair Shop and was told it was going to need new lamp power supply and that exceeded the cost of the unit itself. Beware of those type of diagnostic responses and above all have them put in writting what they found wrong and the part#'s required to fix it. You may find out that they are not exactly quick to offer that information but remember that is what you paid for. Hope this helped and we owe Jadehe a thank you as well for his post.

Found Z6 zener diode shorted in power supply. It's a 6.2 volt zener.
Hope this helps
