Question about Memorex MLT3221 32 in. LCD TV

1 Answer

Memorex LCD 32": after about a year a black rectangle about 24" long by 1 1/2" tall has white numbers and letters show up for several minutes goes away. Then a few days ago a large black area of about 15" wide by 8" tall shows up and you can see thru it, more dark Gray transparent, no letters or numbers, and stays on for several minutes and then goes away. I bought the tv from a friend who said there is a dead pixel, which I can sometimes see just a tiny white spot, but I'm wondering if it is causing the problems.

Check the settings and see if he has any CC1 or CC's activated or any type of Closed Caption. The only time something like this happens is usually when you have it set for CC2 or something along those lines.

SOURCE: Dark black spots around the edges of LCD TV

this issue is tape from the edge of the panel falling onto the screen.You will have to remove the cabinet and the panel from the bezel(front cabinet).remove the screws from the lcd outer edge. Take of the tape.Be very carfull of the ribbon cable that goes to the lcd controller and to the lcd screen itself. They break easy. If you do , its over. you will need a new panel. to much money and work. best to leave it alone.I have fixed it several times for people with warrentys. It is just anoying but will not hurt your tv.

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.

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

Dynex 32" tv picture goes black


If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.

Sounds like 'picture in picture' was turned on. And if there is no 2nd video source, it shows up as a black rectangle. Find a button that is labelled PIP or similar and press it, maybe several times. It may move the PIP around the screen before turning it off.

My 32 lcd tv a black rectangle apears on aprox,


If it is a large black rectangle that blots out the middle of the screen then you need to check your CC (closed caption) setting. Make sure the closed caption is turned off. I'm not up to date on the newer sets, but a lot of the older ones had more than one CC setting. One setting ran the captioning across the bottom, another put it in a big black box in the center of the screen. Most places didn't support the full text so all that showed was a big black rectangle on the screen. Since I'm not sure exactly what your rectangle looks like, this is my best estimate of your problem. Hope this helps.

White Display


Here is two solutions:

1. Grab a LCD Color Tester, Run it through RGB.
- If it is still white its the LCD
-If it not at all either the inverter board is bad or the mainboard.

2. Sometimes its brightness control, look under the manual.

Turn off the closed caption portion in the menu . The text 1-2-3 or 4 is on blanking out the center of your screen . The closed caption button could be on your remote and is being accidently pushed . Good luck
