    I have this exact TV and the screen is not only streched out, but it's even more streched out in the corners. The view is shaped like an hour glass. It looks like it needs an adjustment on the pincushion and the horizontal shrinked. I tried the service menu and it didn't successfully solve the problem. If I just go ahead and take it to a repair shop, what will they charge me to fix it most likely? Oh btw, before this problem with the screen streching out, I also came accross this one problem with the screen having a blank spot (black line) about two inches wide accross the bottom of the screen. The funny thing is, this problem gos away for awhile when I unplug it then plugged it back in.

Although I was able to get into the screen adjustment menu by following the below instructions, I ended up having to have the "pincushion module and 2HV diodes" replaced along with a repair to the deflection circuit.

If you choose to try to system settings, good luck, but make sure to write down your original value before changing any values and make sure that you do not change Parameter #42 (value has to be 247).

Instructions:

  1. TV turned on
  2. Press and hold the "menu" button at the TV
  3. Press and release the "power" button.
  4. Press and release the "vol up" button.
  5. Release the 'menu" button.
  6. The initial security parameter displayed will be 'zero' Change this to '76'.
  7. YOU ARE NOW IN ADJUSTMENT MODE
  8. Use the 'channel up or down' to select parameter 'p'.
  9. Write down the old value of the parameter before changing.
  10. Use the 'volume up of down' buttons to change the barameter value.
  11. When you have made all the adjustments turn the set off to exit.
Note: The Horizontal size it parameter 21 and the horizontal position is parameter 15.

RCA 20F514TD has lost horizontal hold. How can I adjust this? I have found no button or menu option discussed in the manual or by searching.


Horizontal rolling is the fault to your TV I assumes. It is a circuit fault. It can't be adjusted by customer controls. Contact any experienced service technician.

Just got this tv from friend. has no remote. screen is black. sound is good. when you push menu button, white line goes across horizontally the screen.


The horizontal line indicates the vertical deflection circuit is not working. Either the set is stuck in service mode for adjusting color (turns off vertical), or the deflection circuit has failed.

Some RCA TV sets have a "Service" switch in the back, down near the bottom of the set. Most of the newer sets use a combination of remote control and front panel buttons to get into service mode, and that can be turned off by unplugging the set and plugging it back in. Try looking for the mechanically operated service switch in the back first.

Horizontal Lines


RCA is not a good tv brand as far as i can tell but other than that you may need to have your tv looked at before something else happens. You may have 1 or 2 bad IC's.

Screen not centerd


If it is a RCA F27649 then it has what they call a bonded yoke, meaning the only adjustments to shift the picture horizontal or vertical are electronic adjustments via the service menu.

Cannot set Cable Default Channel


I believe you are getting mixed up between channels and programs. Normally program 00 is used for VHS as it has slightly different parameters for colour and brightness. If the TV has about 39 or more programs which can be programmed in from the on screen menu, try using program 20 for the video and 30 for the cable. For this to work you must do the on screen frequency scanning from channels 22 to 69 (UK) and select VCR, CATV, VHF, UHF, etc. I have used program 00 and 20 for two VHS recorders, working on channel 33 and 35 for example, but you must tune them to 33 and 35 on the `Tune' screwdriver hole by the aerial input sockets of the recorders. I expect if your cable unit plugs into your aerial socket of the TV that it has an adjustment for what channel it is on. The TV on screen menu may be different in some countries, so it would help if I knew where you are.

tv screen is stretched too wide comin back from a week vacation, i turn on my rca f27650 to play xbox and i realize that my screen has been stretched out of proportion! i cannot see sides of the proper picture. i swith it to tv mode and the channels on the top left only show half of the first number! after trying to play around wit the menu settings to see if anything can be done to play wit the parameters! i went on my xbox 360 because i knew that there were settings in there to change screen fittings! what i found as a success (somewhat) was that when i changed the xbox screen format from normal to widescreen, the picture was formatted and actually fit the screen....kind off! the screen was no longer stretched and i was able to see the whole screen. even wit this somewhat succes, unfortunately the corners of the image were warped and appear compressed to fit format! i have tried troubleshooting from online but i have been most disappionted. ~ i have kept it unplug for hours / days to try a reset.fail ~ i have researched on how to acces the service menu for my model so i can adjust it but i seem to be finding only instructios for the generic rca service menu! the steps: hold menu, press release power, press release vol up, release menu i havent been able to get to the service menu at all! i thought that i might have already activated it but the screen jus didnt let me see it so i went and tried to acces this generic service menu on my other rca tv! it was a truflat rca model f20t10 ! similar guidpluss menus and all but i believe a bit newer! even on the rca f20t10 i was still unable to acces any service menus!...if you got any info on how i can fix an fit my screen please please let me know! thanks in advance
