Question about RCA P52937 52" Rear Projection Television

1 Answer

I have the same problem. Remote doesnt work either

I think it's the control board on the front of the set because I can remove the cover and mess with this board and it seems to work for a few minutes then starts acting up again. Are replacement boards available and if so from where?

Tv has worked for ever with the remote now remote has failed and the on off swutch doesnt work to turn it on and off How can I program another remote if I can turn it on?

First, check to make sure the front keyboard is not locked out. Press and hold the menu key for 10 seconds then release. If it was locked out, then front panel buttons should work. If no change, you likely have a problem with one of the ten contact switches on that panel. Remove the front speaker grill by pulling it off, then trace the wires from the front control panel (you may need to remove the cover off the front of TV). Unplug the wires to the front panel and try by Remote control. If the remote works, you can purchase ten tact switches and install or just leave the wires unplugged and use it like that.

GE 46GW 948 46 in. Rear Projection Television turning on and off and changing channel buy for awhile then it starts doing that stuff!

I have a suggestion for you---I have seen this set doing this kind of thing before.

Someone has to be just a little handy to try something.

I suspect buttons (there are tiny switches behind them) on the front keyboard are causing your problems.

Unplug set.

remove back cover.

locate the plug that goes from the front keyboard to a tiny circuit board above the middle of the three large black lens inside.

If you can find it (should be easy) unplug it---the remote receiver is on this little board so all you are going to be doing is disconnecting the front controls on the set---set will still work with remote.

If it cures the problem---either live with it and just use the remote or have someone remove the keyboard and repair it.

Let me know if you have questions and if I told you something you did not know, rate this solution as very helpful.

My verizon fios remote control stop to control the 65" cinema series toshiba tv.the remote seems to be ok.The oryginal tv remote doesnt control it also.I think that there is something wron with the tv...

Yes, most likely the sensor is at fault - more precisely it's connections to the motherboard are iffy. You must take the back cover off the tv and reseat them. While you are there check their soldering points - with age they tend to melt and get loose.

Seems like some type of control board problem. Remote will not work on tv, but works other devices. Manual controls are squirelly. Cannot change inputs. Can move to other inputs on menu but when I hit...

Thats a bad button on the front keypad of the tv . The remote does not work because the tv micro sees a button pressed all the time and never listens to the IR reciever . If you pull the front speaker grill off you will find connector ZF just below the keypad or just inside the access panel. If you do remove that panel don't touch anything else.Just follow the wires down from the keypad to connector ZF. Connector ZF is inline with the wires to the front keypad. Unplug it . Then remote will work like normal. Use it like that or have the front keypad buttons replaced.

Volume control slide stuck on screen nothing in remote works or the panel except the channel up or down all else doesnt respond

WS-65809? Unplug set first!

Remove front speaker grill---it should pull out and is secured with pegs.

Behind it you will find an inspection plate---remove the plate---notice the one or two groups of wires coming down from the front keyboard with all the controls.

Follow them to the right behind the inspection plate--you should find one or two plugs---The idea here is to disconnect the keyboard on the front of the set------You will still be able to turn the set on etc with the remote control

With the keyboard disconnected (the plugs if there are two will be different sizes with letters on them so you cannot get them back wrong) plug the set back in and wait about 2 minutes---

Turn it on then with the remote----if set works normally now with the remote one of the micro switches (vol up) on the front keyboard is bad.

You have two choices---leave the plugs undone and just use the remote OR someone has to remove the entire screen from the set and get at the keyboard(it is a small circuit board) to remove/replace whichever tiny micro switch is bad.

Let me know what happens and reply here if you need help of have a question.

Philips 47PFL3603D LCD TV - TV not responding to remote

One thing you can do is take your cellphone's camera, point the remote at the camera, and press a button. You should be able to see the infrared sensor firing.

If you can verify that, your remote's fine.

In this case, what you have is a bad IR sensor board. The part # is:
313926859182. Right now, there are so many of these things failing, that finding the original might be difficult.

Don't fear, though; it's a small part. And, best of all, it's cheap. Expect to pay around $5.00 for the part, maybe a bit more, maybe less, depending on the supplier.

Now, if you are handy with a power drill (fitted with an octagon/star bit for the back of your set), you can remove the 20 or so star-bit screws from the back of your television. Don't worry about putting the set on the floor. If your TV is on a stand, simply turn it around. You'll need to remove the stand screws, but you won't need to take the TV off of the stand.

Now that you've taken the screws out and removed the back cover, look in the lower left hand area of your set. You'll see a 4 inch long circuit board with 2 cables running to it. Pull the cables out (they'll come out easy). Remove the 2 star-bit screws.

One of the board's sides is under a plastic tab. Lift the board out of its slot from the other side.

Put your new board in, reconnect the two cables, reassemble the back and you are set to go.

Expensive repair for a few bucks and a better IR sensor.


This advice assumes that the control buttons (power, volume, channel) located on the side of the set still function. It also assumes you are able to use those buttons to power on the set and verify that you still have a picture on the screen.

I have an LG 37LC2D LCD TV that is locked.

Bad filters on the main board or a bad AUX REMOTE jack on the back of the unit (also part of the main board) are the cause of this problem.

Try plugging in any jack that will fit into the AUX REMOTE jack on the back and then pulling it back out. This may fix the problem or remove any dust that may have collected in the jack. If this jack has something plugged into it (or goes bad) the TV will no longer have remote control operation (because it thinks an external remote box is being used). If this does not work then the main board will need replaced.

Note, many repair techs will think the IR board is bad (the Infra-Red Receiver board) at the front of the TV, but this is usually not the case with this model.

Hope this helps, please rate my solution.

Not all buttons on front work

Sounds like the front panel buttons are your trouble,you can disconnect these buttons from the rear of the set ,unplug the set and remove the back cover,just below the top screws you removed you can look under and see the top of the tubes,in front of the middle tube is a small board,unplug the right top cable and this will restore the set,just the front buttons will not work,use the remote

RCA 52 inch TV (turn on problems and channels rolling) HELP!

Your set uses the 195 series chasis. The only thing I can think of which would make the channels scroll by themselves is a contaminated PC board and pushbuttons behind the buttons on the front of the set. This is usually the case when spray cleaner or some other fluid is sprayed or spilled on the screen, and it drips down onto that board. To prove this, remove the back cover and on the top of the main chassis, where the top of the picture tubes are, is a small PC board with the remote reciever and a couple of jacks. The smaller jack is for the speakers and the larger jack is for the front panel PC board. Unplug the larger connector which goes up to the front PC board and then turn the set on with the remote. If the set works normally, the front PC board will have to be removed and cleaned or repaired (or just leave the jack unplugged and work the TV from the remote only). If you do not have any experience working inside projection sets then allow a qualified tech to handle it for you.
