I have a Memorex MVUC821 8" TFT DVD Player. Upon power on, the red standby light turn green. The unit checks to see if a dvd is the player and then cycles the dvd player since not disk is present...


Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Compliments of the season.

What current draw is expected when using an AC adaptor please? Forde


Well for a TV such as this about an Amp or so, like 2 Amps would be too much suggesting a fault.

I have an memorex mts stereo t.v.,hooked up to it i have an xbox 360 for my nephew, i do not have the remote for the t.v. to turn it into video mode, i have a universal remote, and have the code for the...


i googled codes for the t.v., and also googled for remote codes, it took me all but 15 mins and i had both the remote code and also the t.v. code. It worked almost right away, thanks anyway, also you should consider the fact that if everybody knew how to get stuff for free, then you would`nt even have a site, i think it is ridiculous of you to be charging so much for one small piece of info, but i guess thats the way the cookie crumbles

I have Dish sattelite and it won't work with memorex under cabinet. They said I need a cable box in between the dish receiver and the tv. Why is this?


You need a receiver for each TV you want to receive the reception on. Your dish receives the broadcast signal from the network and your receiver decodes and recodes the signal to view on your TV. The companies have created their own proprietary equipment to accomplish this to keep anyone and everyone from simply installing their own dish and receiving all of their broadcast channels for FREE. In the olden days when satellite and cable TV was new, that is exactly what people did. Remember those gigantic dishes some people installed in their yards? They would intercept the signals coming from the satellites and hook up directly to their TVs. The companies got smart and started to scramble the signals going up to the satellites to make these home owner dishes obsolete. Because the signals are scrambled, you now need a receiver to un-scramble the signal. I hope this helps and good luck. Please remember to vote d368a18.jpg if you found this helpful. Thanks.

If you mean does it have DTV tuning, the answer is no. (DTV is the new digital broadcasting which replaces the current analog system this coming February.) All TV's made after March 1, 2007 must have the digital tuning, but your set was made earlier than that. You would need to get a converter box if you aren't connected to cable or a satellite.
