Question about Memorex MLT1921 19 in. LCD TV
Picture worked for about an hour this morning and suddenly the picture went out (black screen), but sound works fine. Tried unplugging,powering on/off blanket over TV, etc. Makes a light screeching type sound for 5-10 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.

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.

If the TV has been moved around or traveled , it may be a loose component or a solder joint / wire came loose. If you are going to junk it , then have someone you know and trust with ability open the unit and closely scan the board connections . Some soldering work is poor enough to come apart with use. Good Luck.

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:

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!
