I am going to assume that you have not already found the answer to this problem. It is actually pretty common for flat panel televisions in the winter to be too cold to turn on. What I did when faced with this problem on my 32 inch memorex was turn it on for 30 minutes while covered with a fleece blanket, than turn it off. When you turn it back on it should work...did for me!

SOURCE: memorex tv MLT1921 will not power on

I work for Memorex tech support. Our number is 800-919-3647.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

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

SOURCE: I turned on my tv

LCD sets (other than those very new) use fluorescent back lighting to produce the picture. Those lights require high voltage to ionize them so the problem could be either the tubes themselves or the inverter that produces the high voltage is failing. Anyone with some degree of manual finesse and possessed of logic can cure this problem but it may be difficult to identify the failed part accurately meaning that if you 'shotgun' the problem, you would need to replace both the tube(s) and the inverter board. The latter is in most sets as a separate assembly which derives its operating voltage from the main power supply and will be obviously attached to the fluorescent tube(s).
The board will have to found from the manufacturer or a company that disassembles scrapped sets.
Check with the site below for availability:
Jimmy's Parts
Search on your set's model number and the term 'inverter.'
The tube(s) can be bought from several US suppliers.

I have a memorex. I am getting sound but no picture. When powered on, the memorex sign shows up but then no picture just sound. Also makes a slight screeching sound for approx 10 sec. when powered on.


I guess the blanket draped over the TV is intended to give it a "timeout". Anyway, you will likely conclude eventually that the internal power supply has failed.

My t.v. turns on for 20 seconds then it just cuts the picture off but i can still hear the sound


The way to test whether or not the television needs to be repaired is to do some things to it after it has cut off the picture. Making sure you can still hear the sound but no longer see the picture turn the volume up and down. If you can hear the volume increasing and decreasing, but you cannot see the volume indicator itself on the screen then you'll know that possibly the inverter(s) is/are loose or that the inverter board needs to be replaced. If you can see the volume indicator moving back and forth across your television screen then you might have a problem with your signal source i.e. your set top box (cable box/satellite tv box), your connecting cables or the connections themselves.

The tv briefly powers up shows the memorex logo and then the screen goes black no picture, but stays powered up. And will not allow or show any functions please help


The poroblem can either be the 12~18vdc power supply section is not supplying the power to the backlight inverter board or the inverter board went out, you need to check voltage on the power supply, also look to see if you see any caps with leaking/bulging top.
See example of failed TV and monitors here:

Picture goes off and on every couple of seconds


If you are hooked up to a HD source if the signal is too high will cause this to happen. Normally this will happen due to signal interuptions such as signal being low will cause freeze, too high will cause it to go out and cause the TV to show default blue.
Good luck to you.
