How do I set up my memorex MLTD2232 tv for cable use

I could not find any manuals for your model number, but the instructions for a different Memorex model may be close enough. For example, the cable setup instructions provided for the MLTD2622 are very similar to those for other brands of televisions. Look on pages 19-21 of the manual for the MLTD2622.

The red light on my Memorex MLTD2622 does not shine and the tv doesn't even come on anymore how do I fix it

Aside from checking you have power to it and the fuse inside connected directly to the cord is good:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

No power

Look at the power supply first; look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

Bought Memorex MVD2059D 20" tv w/built in DVD player 7-21-09. Did not take out box until I drove my son 4 hours away to college on 8/22/09. TV worked 8/22/09 and on 8/23/09 the power went out and tv never...

IF the Standby Red Light does not come on when you plug in the TV:


1) Check fuse on back panel next to power cord. Pull out cord and pop fuse holder out. On an ohmmeter, it should read 0(short)-that is a good fuse.

2) Check the fuse on power supply board next to power connector. It is soldered onto board.

3) Be careful with this step: With all boards screwed in place, plug in TV and then unplug it. Next take a Voltmeter set on 200 Volts and test large electrolytic cap in middle of board-should have @100-200 volts on it. Do not short the capacitor-big fireball flash explosion if you do!

If 1-3 test OK, then:

D10 is shorted. HER304 in middle of Power supply board near large electrolytic cap. Replace with same diode or Radio Shack 276-1144 3A 400PIV Diode. PLEASE BE CAREFUL WITH HIGH VOLTAGE PRESENT ON POWER SUPPLY BOARD. UNPLUG POWER CORD!!! OBSERVE PROPER POLARITY WHEN REPLACING DIODE-LOOK WHERE THE BAND IS.
