Question about RCA F32650 32" TV

1 Answer

Help me... The tv was changing channels and volume by itself, and we took it to get it fixed, but it kept happening afterwards, and finally it stopped working, making only a nonstop high-pitched sound when it's plugged in...

Volume on the WD 57733 turns up to full blast by itself. Cannot turn on the mute button using the remote.


volume button on your remote is stuck in the increase position. try another remote if possible or remove the remote batteries so you can atleast use the TV manually

Use following steps to reset channel, but I lost the sound 1. Unplug TV 2. Press Channel up and Volume up at same time, while plugging TV back in (two person job - it will pull up a service screen) 3....


img{-moz-force-broken-image-icon:1;} Same no sound issue happened to me; except I stopped at adjusting vertical size (unfortunately it seems horizontal cannot be set thru service mode; which was my original intent). Complete lost of sound signal processing; oddly enough speaker volume leveling did worked. (Eg, audio-in woks; so a big WTF?!) I suspect something to do with not recovering properly the data bus from muxing the volume input keys; ie, some kind of weird service/back-to-normal switch bug. I've waited for a couple of days for the damn thing to unlock itself out it (like some stubborn transistors seem to do); but to no avail. (BTW, only dif between TVs is that mine's a slightly smaller and cheaper model, a 19U-M100S; a minor branch out of the main line.) I'm afraid something did "burned out" and that the only real fix is to actually change the "defective" part. Had I known silly sh1t like that could happen, I obv would've not messed with it to begin with. It's just ridiculous, and lame. Besides being obsolete. In any case; I also think it's nowadays better to get a (full) digital one (wisely cost effective).

Hi my RCA 27 Truflat tv keeps changing channels , the volume keeps going all the way up and it is turning it's self on and off. What could be the problem and how to fix? THanks


The micro buttons on the tv are causing the problem. Mine kept going up in the channels like you are holding the button down. I took the button board and clipped to prongs on the micro switch to the channel up button. It has three prongs on one side and two on the other that you clip.I use the remote all the time any way and it will not affect that.

Why does my RCA TV cycle through channels on its own?


this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t

TV turns itself on, keeps changing it's own channel


the problem is with the control panel of your tv...make sure your remote doesnt have any part in this...just remove and the batteries and check if the channels still are changing.....see if the onboard switch for channel changing is stuck ?..if stuck u can use homemade tools to pull it back......if your tv is within your gurantee period...just giv a call to customer care....if not u can take it to a local repair shop...there is nothin that u can urself do to make it right ...sorry....for further info contact at

You may have a sticking button on your front control panel. Sometimes they become intermittent and cause crazy things to happen. I've found this in RCA tv's and GE's are made by the same manufacture. Stargazer

TV will suddenly change channels, change volume, or go to set up screen by itself


yes and this is a common problem! First lets check out the obvious/ when theis fault starts to happen take out the batteries out of the remote control. If the problem stops then you need a new remote. If the proplem persist the remote sensor assy is bad in the tv set. Ive never heard a cable box causeing a motherboard to act up?? Wait arent mother boards in computers?? lol. believe me you need to tell the tv msn to replace the rmote sensor. Now in an extremly rare cases the microprocessor was causing the problem BUT highly unlikly. Good Luck
