Red shadows around images on screen, setting convergence doesn't help

All images on my tv have a red shadow around them. My husband adjusted the red lense in the back of the tv, and the shadows are smaller, but now there's no red in the images. Makes for dull tv viewing.

WHERE IS THE RESET BUTTON ON MY TV


What is the brand name and model number of the TV. Can't say anything without these information. If the set is not too much older model, there will be no such button marked as "reset". For modern sets, if you have to do a reset, you should enter its service mode. It is somewhat skilled procedure.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Samsung plasma TV model #pn42b400p3dxza problem with no image. The TV has sound but no image. I've tried using other components on the TV like RCA jacks with a separate TV digital tuner. Thank you


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
Check whether Va & Vs voltage come to the display panel, from the main power supply regulator board. If not, the SMPS board [power supply regulator board] is faulty.

WHY DID MY VIORE SCREEN RESIZE TO SMALLER SCREEN


Screen size depends on the broadcast signals aspect ratio, the TV adjusts for that automatically, the picture can have no bands or be banded top and bottom or on both sides.

I have checked cables and different methods of connecting, but the white and red audio out of my PVR appear to have stopped putting out sound.


Go through the setup of the PVR and check the sound settings. It sounds like it's only producing digital audio, that's why it works with HDMI but you want analog, so set the audio to stereo, or try every setting to see what works!

Samsung TV Displaying Dual Images. It appears as 2 of the same images offset from each other. There are also some lines in the images. Talked to samsung and they wanted to send a tech but I simply can't...


Overlapping video signals are generally adjustments made when turning various pots on the rear circuit board. You may need the service manual to follow the directions on how to reset and stabilize the picture. If you cannot be your own technician; you have no choice or other options.

How do I make my Zenith TV clear up?


i'm sorry sir but your tv set needs to be repaired, it is not apart of normal operation for the set to exhibit such behavior, furthermore this seems to be a hardware issue and I do NOT advise YOU to disassemble the unit, try and adjust the color via the menu to help but the set needs repair beyond your scope, leave it on if you can, it wont hurt much

My tv has gone some orange colour


Try unplugging your tv and anything connected to it - you might want to take a picture first so you have a reference. I would also unplug everything connected to the tv: cable, stereo, etc. Wait a few minutes, then plug in and re-connect everything.

You can also go into your TV's setup menu and adjust the picture settings - try restoring the default settings first.

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.


also you can call for tech support at Dial 1-800-VERIZON (1-800-837-4966)
