Question about RCA F32648 32" TV
I have a problem with my OLDER MODEL RCA HOME THEATER PICTURE AND PICTURE TV WITH GUIDE PLUS When I turn the unit on, it scrolls between the Guide Plus and the menu more of the menu than the guide and won't allow me to change channels or control the volume. Some days it won’t allow me to turn it on at all with or with out the remote. The only way to turn the TV back on is to hit the Volume down button on the TV it self. But when we have to turn it on that way a sequence of red numbers appear on the bottom of the screen that are highlighted in blue. When that appears you can’t even control the TV unless you hit the CH up button. In order to turn it off you have to hit the CH down button on the TV when the menu is not flashing on the TV or just unplug it. On top of every thing else the TV will mute it self for hours while the menu is jumping from on option to the next. Please can you help?
I am an electronics technician who just happened have been given the same set as you because it was giving the previous owner the same problem. Since I am confident in my trade, I took the set and diagnosed noise in the remote receivers input to the cpu.
What this means is that a capacitor( or something) wasn't working properly and was either not filtering the noise out or it was introducing noise into the data stream that controls the TV through your remote control.
My fix was to essentially cut out the entire remote control input to the TV. Since I have a directtv box to give me remote control, I don't care if the TV's remote works anyway.
The way I did this was to open up the unit and find the front I/O board were the buttons meet the switches for power,chaennel, volume, etc. On that board there is a plug with white wires and one black wire. The two wires to cut are the one next to the black wire and the one all the way at the other end of the black wire. These two wires are easy to splice back if you do not like the results of this procedure so that there is really no risk of damaging your set. If you wish to verify the proper wires to cut, they are the two wires that come from the IR receiver's side of the board YET DO NOT GO TO THE OTHER SIDE WITH THE BUTTONS! There is one wire that does indeed go to both sides.
This may not be a perfect solution but it is free. I hope that this will help someone out there.
