Question about RCA B27TF680 27 in. TV/VCR/DVD Combo

RCA model f32649

Hello,My tv will not get our local stations 2,3,4,5,6 etc. I have cable and it recieves all the cable channels but not the local ones.I have checked and the channels are not blocked.the vcr will not play either.I removed the cable from the vcr and hooked it directly to tv and still same results.My other tv's work fine so its not a cable issue.

Hey thanks for the help.I was able to get those channels working by using the A/V outputs on my VCR but aggravating switching around channels etc.but a great temp fix.Let me ask you this,,,Is the tuner the unit that also switchs the bands VHF and UHF back and forth?? I think maybe the switching contacts are stuck and that is why I'm able to view the higer channels and not the lower ones.Is this tuner soldered in or does it plug in??I have not taken the back of the TV off yet and looked at it and was wondering if perhaps I could dismantel the tuner and clean it up with some type of contact cleaner???thanks for your help...

Thanks Benimur,
I have found a tuner for $49.00 on the net.Is this tuner hard to replace? Does it plug-in or does it require a lot of soldering? Thanks again

We have an old RCA floor model tv and all of a sudden we have lot all our UHF channels. When I went into programming it said they were erased. I re-instated them but that didn't work. This tv was given to us and there is no book available. Is there an electronic problem or is there something I can fix?

Hi, Based on your post/description, it would appear that the TV tuner of the RCA is at fault. Chances are the the VHF Low is not working right but the VHF High is. This is an inshop repair probably requiring component replacement. You may want to confirm by checking your TV's setup in the menu, you should have Cable selected instead of Air or STd and do a Memory + (scan and add channels). If still a no go, then back to the tuner suspect. The VCR will not display any movie since it normally transmits in Channel 3 (which is VHF Low). If there are no other problem with the VCR then you might still be able to use it by connection it to the A/V inputs of the TV. If the VCR works in A/V mode, then perhaps you may want to save the repair expense of the RCA TV and use the tuner of the VCR to watch TV and switch channels. Post back should you need additional information. Good luck and kind regards.

Hi again,

Since you are now able to watch "local stations 2,3,4,5,6 etc." based on your recent post, then your main problem is solved.

As to try and repair the TV using contact cleaner, am afraid it will not work. Your particular model doesn't use the rotary channel selector where there are tiny finger tips selecting some coils and capacitors to tune to a channel. Rather your particular model uses a tuner block with a PLL based tuning system - it is digital and there are no electro-mechanical parts.

Cheers.

I would guesstimate the connection points to be between 4 - 7 plus 4 grounding ends. There might also be 1 or 2 lug-in type connector.

I think you are confusing the channel on the tv and the channel of the cable company that is not something that you can pick up with the scan tv, scan tv is good for picking up local channel meaning air channel that we get with a antenna only not the cable chanel

Hello! I have hdmi and rca cables for my ps3. However the tv (sony htc800dp does not support hdmi. i tried the rca connections but that doesn't work neither. are there adapters for me to buy. Or what...

You have 2 RCA inputs, one RCA output, an SPDIf input and a digital optical input. If you have an open RCA input, that should work for you. Manke sure you go through the recievers menu to make sure you have selected the proper channel(AUX, Vid 2, etc.)

I had the same problem and eventually found the solution. the tact switches behind the front panel buttons will leak when they get old causing them to activate on their own. your channel up or down button is stuck on. take off the back cover and you will see a small clip in circuit board behind the front panel. take out the board and remove the channel up or down switch and your set should work fine again. the remote will still work fine for changing the channels.

Television only locates 7 channels????!!!!!

Hi there!
If you cannot receive all channels it may be a fault with the antenna or the tuner may be faulty. If you have a VCR, you can tune that into the TV first and then tune the VCR to see if you then receive all channels. If so, use the VCR position on the TV to view and select or change channels on the VCR only. Good Luck,JUS004

Programming my rca universal remote for basic cable the stations wont turn

I can only suggest that you Double check you have the connections correctly set ie. coax ariel to ,(dvd /digi box reciever ect...)
Also check again (& i know this is state the obvious)
your tv manual. IF you havent a manual do a google search for your tv (make & model) & search for a manual.

Ive have had a simmular experience when programming channels to a Vid-Recorder & when i finished the channels dissapeared.

I realised I didnt have the video set to the correct channel with the tv usually channel 9 or the highest channel on the tv.
So i waisted a good half hour for nothing.
