RCA Projection TV MM52110 Won't Power Up

My RCA 52" MM52110 projection TV will not power up from the remote or from the button on the front of the unit. Based on my internet searches, this is a common problem. How can I fix this myself, since it is not under warranty any longer? I have a friend who is TV-electronics-savvy, but he needs a schematic to be able to troubleshoot it. Where can I get a schematic? I have tried several web sites and they don't have the schematic, since (they tell me) it is only provided to authorized RCA service/repair centers.

    i have the same problem

  • swampyjack Jan 05, 2008

    Sounds just like mine. It will not power up, just comes on, goes off, comes on, goes off @ 4 times. It only stays on a second before going off. I expected better from a unit I paid so much for.

    I have the a simiular problem. But I do have a green light tha come on for about, then it shuts off. I did find a circuit board where the TV\cable Ant plugs in to. On this board there is a resitor that has gotten hot enought to start to melt the circuit board. The board number is 1519592k. I was thinking on replaceing the resitor # r25611. but I would think there is a componet ahead of it that might of fail... any suggestions???

    The unit will not turn on with remote or front of the unit. There is a green light that comes on for about a second and then goes out.

Being able to read a schematic and understanding how a TV works are two different things. These chassis that RCA used in these sets can be somewhat complex to troubleshoot. I would geuess that unless the power light comes on at all then you have a dead power supply in the TV.

you must check the light indicator if how many times does it blink which tell the main problem or the error code of the tv. either the power supply doesn't work normally or the lamp need replacement.

The tv won`t turn on. its it a fuse


Do you mean is it a fuse? Because if the fuse is blown that means more than likely there is something else wrong with it...probably in your power supply. What I recommend is to plug it in and listen for power (high pitched buzz), if you cant hear that...it could be anywhere from a diode to the HOT. If you have an om meter, I suggest checking thos first. What happened before it went out? and are there any LEDs that turn on in the front?

How can i change the aspect ratio on RCA mm52110. the HD picture is stretched tall but very clear.


I'm going to take a stab at this out of the dark but okay!
1) is there an 'Aspect' or a 'picture size' button on your hand held remote control?
2) If you scroll through your 'On Screen Menu's' do you find a feature that will change the aspect or picture size?
Many of these TV's have this button feature on the remote control.

RCA MM52110 tv


I had a repairman out to look at mine today. He said it was the high voltage protecter kicking off the TV as soon as you turned it on. $400 to $600. to repair.

I love this TV but guess I'll go shopping for another plasma. I have one Plasma TV in the bedroom 50" Samsung (top of the line) it doesn't have as good of a picture as my old RCA.
