Question about Memorex MVD2042 DVD Player
I own a memorex mvd2042, have had it about two years. Today I went to turn it on. The standby light comes on when you plug it in but nobody is home. None of the front panel lights come on and it doesn't respond to the remote or the buttons on the front. There is currently a dvd trapped inside. What do you think? Should I just by a new one or hope it decides to come back. Mel
All, I **w have a second one of these DVD players in my possession, and have found, again, a bad capacitor (C411) in the power supply section. Replacing this discrete component (it is a 1,000 µF, 16V electrolytic capacitor; replace the part with a 1,000 µF 25V (or higher voltage, keep the capacitance, the 1,000 µF, the same, that still fits onto the board) electrolytic capacitor part) has fixed my, will **t power on, suddenly **n-working DVD player, into a working one. Replacing this capacitor with a higher voltage part is probably a good idea: the 16 volt part seems to it a bit undersized, as the top of the can has bulged, a sure sign the maximum voltage of the capacitor has been exceeded for an extended period of time, boiling the electrolye inside and bulging the can.
Total cost was less of this repair was $1.59 and that was at Radio Shack (Part Number 272-1032) for a 1000µF, 35V (20%), Radial-lead electrolytic capacitor. And it fits in the same space as the one removed.
A **te of general use for troubleshooting these types of consumer electronics (read: CHEAP!), assume the least expensive parts went into them, and k**w that the most expensive parts are **t the IC's but the discrete components, and, usually, the most expensive of those compenents are the capacitors. Start there, and look for bulging, leaking and/or corroded parts. These parts should have very flat tops and strainght sides with ** discharge. Any deviation indicates a bad part. This can usually be confirmed with a multimeter continuity tester; they are usually shorted and do **t hold any charge.

Memorex MVD 2042
Red Light on front On but Dim,and No functions work.
I found the top of the µF 1000, 16V capacitor on the power supply circuit board bulged up and it also seemed like it was warm compared to all of the other components. (The unit had been plugged in for about a half hour). I got the Radio Shack 1000µF, 35V capacitor (Part Number 272-1032) and soldered it in place of the µF 1000, 16V capacitor. One hint I would add for others new to this type of repair. There is a positive and a negative terminal on those capacitors. So make a note of which way the old capacitor is installed and put the replacement in the same way.

Thanks to J. Roebke! You "Fixed It!"
I also have the Memorex MVD2042 dvd player that just stopped working after a few years. Standby button was lit (red) but it would not power on. Tried pressing Standby button and unplugging power cord per manual, but still nothing.
Read J. Roebke's post. Glad I did!
I opened the case and found the 1000uf 16V capacitor on the power supply bulged on the top. Went to the "Shack", got a 1000uf 35V capacitor for under $2. A little soldering time later, and it works fine!
CAUTION - for those who don't know, all capacitors store electricity. So if you try this, be VERY careful. You could get shocked or worse. Or let someone a little more familar with electronics do it for you.
To remove a disk from the player, if you choose not to fix the player, open the case, look at the left side of the disk drawer and find a white gear. Gently turn it with a small screwdriver, back and forth until it begins to move. It should eventually unlock the drawer and allow the drawer to be pulled out so the disk can be removed.

I had the same issue, opened up my unit and found the same cap, (C411) bulged out

Thanks to the solution posted by JRoebke I was encouraged to try to troubleshoot my MVD2042 DVD player. Opening the thing I found the power supply was dead and 3 caps were abnormally warm. I replaced all 3 of them, but had trouble finding ones with such tiny footprints with the same values. The manufacturer obviously cut corners using caps with under-rated ripple current, no wonder they blow! The larger one was a 2200uF 10V, which I replaced with a 1000uF 25V. The smaller ones were both 470uF 25V which I replaced with the same value but larger case (Digi-key P10274-ND). Works great now.

Mine blew out an inducter, L50, on the board in the center rear of the unit, rtght next to the white 5 - wire connector. I'm going to try to replace it if I can find a number on it - all the inductors (marked L**) seem to be plain black cylinders. I'll post if it works.
