Question about RCA F36650 36" TV

Ghost in the channel selector

The channels on the TV tuner started to change all by themselves. First it was occasionally but now it is all the time. While this is going on, no other button on the top of the TV will work. Most of the time, you have to turn the TV off using the remote only. If you are lucky enough to get the menu to come one, you find it starts switching down the menu list by itself, as well. It is as if you are holding down the channel button constantly. I even tried to have only channel 3 set in (since we have a cable box) but found it also switches to the various other ports as well. I've tried unplugging the TV, I've removed the remote batteries, I even tried the last resorted "beating" on the TV. Still the channels change away.

Re: ghost in the channel selector

Simply pop off the top channel selector/power pad and free the buttons. It worked like a champ!

Re: ghost in the channel selector

The problems due to the microprocessor on the remote reciever present inside the tv .i think the remote is normal working. as the only problem with your iinfra red reciever microprocessor.microcontroler circuit. Replace the IC to solve this. Check electrolytic capacitor coupled to the memory block of the micro processor. Contact service if you are not well verse doing all this rectification works. it is off high risk and caution
thank you !

Re: ghost in the channel selector

With further investigation, I found that the problem was actually with the channel selector button pad on top of the TV. This is easily removed and I found that this pad was a sealed single unit. But by disabling the suspected "stuck" channel down button (using my trusty pocket knife), this stopped the channels from changing on their own. Now I can still use the menu button along with the 'up" channel selector button when I need to change any menu items and the remote still works fine. It would be best to replace the entire button pad but I am told that RCA has discontinued supplying any replacement parts for this model. That is a rotten deal since this TV is only 3 years old. It looks like this will be the LAST RCA I ever buy. In any works fine for now.

Tuner appears to be stuck in channel 4. Cannot change Channel.

It is a tuner selector problem, either the processor controller ic is the problem, or the selector ic. The easiest solution use a VCR as your channel changer, and check to make the VCR is set to channel 4.

You just do autotune to receive all channels. In this mode TV will tune through the entire channel band automatically, and finally will stop tuneing, and will show the first channel receved. You must be patient for these time. about two or three minutes, without disturbing is process. The tuning process follows.

Auto Tuner Setup

In Auto Tuner Setup, the TV automatically scans

t h rough all available channels, memorizing the active

ones and skipping over blank ones or channels with

weak signals. This means when you scan (using the

active channels

Press Right or Left button to operate
Press Vol+ or Vol (--) to choose CABLE or AIR
Press UP or DOWN button to move to START
Press Right or Left Button to start Auto Tuner Setup

you could be experiencing two problems. the first part of your description states the static with two horizontal bars, this problem is usually erratic and it is caused by a defective varactor tuner(this happens while watching a channel thru your channel selector) the second part that it also happens while using the front hookups could be taht the front input connectors have developed some loose solder connections and thus the video problems (very common problem)

Magnavox TV

It's possible that V-chip is locked.. Go to the menu and see if the lock option is active... The backdoor password is 0-7-1-1 twice.. Entering it the first time, if it times out, will display "incorrect" just enter it again and it should ask you for a new password..
If that's not it let me know and we'll try a couple other things.

Channal selector down

Sounds like it is changing to another video mode that has no input so the screen is blue. On many tv's the channel buttons also act as video input button. This should happen with the buttons on the tv. If you are using the the remote I am not sure why it is acting like a video input button. Try changing video to tv with one and changing the stations with the other. I take it you are watching antenna tv and not using cable box or satellite. If this does not work and you have old vcr just use it as a tuner to change your channels.
