Question about RCA P46921 46" Rear Projection Television

1 Answer

TV turns on and then, after a few seconds, picture changes to "double vision".

I actually have a model# P46920 BL. All of a sudden, I turn the unit on and the picture is clear but, after a few seconds, the picture turns to what is best described as double vision. I can turn the TV off and back on and the same process happens. It is always clear when turned on but eventually changes. Help?

Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

LG LED TV has sound but no picture. Went out all of a sudden. Image shows with flashlight. Flashes for split second on power up and power down.


Your screens back light has most likely failed and or the voltage controller for the back light, both should be replaced.

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years

LG 26LH2000 television. Last 2 days when I turned my TV on there was only sound, and black screen.


back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

How to reset your Set Top Box to fix common problems FiOS TV Residential...
Resetting your Router and Set-Top Box can resolve a variety of issues such as:
  • Missing Interactive Media Guide (IMG) or On Demand menu
  • Unresponsive Set-Top Box
  • DVR recording problems
If you are having any of these issues, you may need to reset your Router and Set-Top Box. Will resetting my Set-Top Box erase the selections I have programmed into my remote?
No, all settings and selections you've entered such as device codes, favorite channels, and recent On Demand selections are saved and available after resetting your Set-Top Box.

Resetting your Router and Set-Top Box
Always reset your Router first and then check to see if that resolves the issue. Resetting your router may be all that is needed.
Important note about your router To avoid problems with your FiOS TV service, make sure your router is plugged in and turned on at all times. Even if you are not currently using the Internet, your router still needs be turned on so that FiOS TV can function properly.
To manually reset your router:
  1. Unplug the power cord to your Router for 15 seconds and then plug it back into the electrical outlet.
  2. Wait 30 seconds and then check to see if this resolves the trouble. If you still have the problem, follow the steps below to reset your Set-Top Box.
To manually reset your Set-Top Box:
  1. Unplug the power cord to your Set-Top Box from the electrical outlet for 15 seconds and then plug it back in.

    Note: Don't confuse the power cord that provides electricity to your Set-Top Box with the coaxial cable that is connected to the back of your Set-Top Box. Unplugging the coaxial cable will not reset your Set-Top Box. Since many issues can occur if your coaxial cable is not securely fastened, now would be a good time to check to ensure all connections are securely connected.
  2. Wait for the time to appear on the front of the Set-Top Box, then power it on.
  3. Wait several minutes while the Interactive Media Guide updates.
  4. Check to see if this resolves the trouble. If you still have the problem, your Set-Top Box may need to be re-initialized. Contact the Fiber Solutions Customer Support for further assistance.
I have to reset my Set-Top Box frequently, is this normal?
No, if you routinely have to reset your Set-Top Box more than three times a week, it is likely there is an issue with your Set-Top Box that needs to be resolved. Contact the Fiber Solutions Customer Support for further assistance.
