It looks like that is your optoisolator and the part markings are the 817.

No power


The outlet that the unit plugs
into... Is it 'hot'? Plug in a known working Table
Lamp. If you have power, the problem is the unit.
Where the cord goes into the unit, locate the Power
Supply. Carefully check for any cracked, blackened,
or broken components. My educated guess is that
a small fuse blew, as did the Metal Oxide Varristor,
which is either a large blue or red disc shaped component
near the power transformer. If the fuse is blown black
inside the glass, this indicates a short, and would require
an Ohm Meter to locate it. If the fuse is blown so that
the element inside just melted open inside the glass,
this indicates an overloaded condition, and would require
that the fuse be replaced with a rating 1/4 amp greater
than the original fuse. Why? because most fuses are
under rated to insure that they will need service to keep
people like me from starving! Trust me on this one.

good luck!

DVD player won't turn on. The red standby light is on. But the player does not work. I've tried unplugging it for 30 seconds but no change


If you didn't have any or have a good power strip the internal power supply could have gotten damaged, if it is under warranty get it replaced. And make sure you have a power strip for electronics at a mininum.

Does not come on?


hi, your memorex dvd player has a circuit that generates the different voltages to supply to the different operational circuits in the dvd device(micrprocessor, spindle,sled motors,preamplifier etc.)it's called a power supply and more that likely it's the circuit that stopped working. It might be a good time to replace it because the repair cost could be very close to the price of another one.

My Memorex MVD2042 DVD player isn't getting any power


If you are plugging your DVD Power Plug into the TWC Box. Unplug it and plug it into a 'known' hot socket, (wall..con strip.etc.). Ensure the AC plug is inserted fully into the DVD player. The TWC AC connection may be disabled.

Put dvd in starts to spin but stops and displays no disc


ive seen this in countless DVD players either 1.the laser mech is toast or
2. the laser driver cog's are missing teeth

either way you need to replace the laser mech you can normally order one from a electronics service center to fit or you can contact the company/manufactuer and see if you can get a laser mech for the unit
now most cheap DVD player manufacturers do not supply spare parts as there made on the cheap in china and should when faulty be thrown in the bin and a new one be purchased! because it is not worth fixing!
hope this helps,ben

well I use to buy these things at servicing stations, depending what brand your dvd was.
but I sugest to buy a new dvd player, there is a posibilities that the high voltage just blew off some parts and components too.

BUT.. try to check your fuse first maybe thats the one just blew off. change it and try it again. at this time make sure everything is good and ready to go, and test.

Hello NOUSHADK,
I have good news and bad news for you. I'll give you the good news first. You know that new DVD player you have been wanting but never could buy because you already had a DVD player? 
Well, let's just say that you don't have that problem any more. When you dropped that screw on that resistor, you not only caused the fuse to blow, but you took out a few other components with it. This type of power supply is called a switching power supply because it takes AC voltage and then converts that AC voltage to DC voltage to power part of the circuits in the DVD player, then it takes some of the DC voltage produced and uses it to power an oscillator which provides a switching action for a Power MOSFET which is used to drive a switching transformer and then that voltage is converted into DC voltage for the other circuits not powered by the first power supply. Now this creates a problem, because when these types of power supplies blow out they take a lot of components (active and passive) with the blown out component.
Now for the bad news. These types of supplies are very seldom repairable, not because you can't find the parts and not because you cant find the layout, but usually because the parts are hard to find, in the case of the MOSFETs, the Switching Oscillator, and other active components.  Also, the schematics for these devices are not to be found anywhere even by locating the manufacture. This is because most of these units are put together in Taiwan or in Bangkok and then branded by a company, meaning the company whose name is on the unit is not the company who manufactured the unit. So schematics and service diagrams are usually not to be found.
I know this may not help you, but you can try to find the Power supply manufacture by using google, and getting them to send you a new board, or you can try to repair the board yourself, but remember you will have to hunt down at least 3 bad active components and a number of bad passive components.
Thank you,
