No, there is not. Its normal to replace the whole applicance.

Thats the way it works. You have to adjust the other colors to the red. You adjust the red from the back of the set using the convergence magnets on the tubes. Then you adjust the other colors to match the red. It's much easier if you have the plastic screen from Toshiba used to align this set.

Sounds familiar. When you say it takes time for the picture to come on, do you mean you have sound until then?

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.



Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix


You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

sounds like something in the standby voltages most likely a regulator or leaky diode causing the problem.

This sounds like a problem either with your internet/network connection or Netflix. i would recommend a few steps to isolate where the problem is:
Step 1. Use another device, e.g. tablet, pc or laptop on the same network as your Blueray device/WII and see if you can connect to Netflix.
** If you cannot connect to Netflix, go to step 2.
** If you can connect, Netflix is fine, the issue is with the connection between your router/modem and the Bluray/WII console. Go to step 2.

Step 2. Take your laptop/ tablet and connect to another network, a friends or neighbors, or a hotspot from your phone. Then try to connect to Netflix.
** If you are able to connect and watch Netflix, the issue is with your network. Go to step 3
If you are unable to connect to Netflix, you may have a problem with your account. Contact Netflix support, who are normally very good at trouble shooting the problem.

Step 3.
** On the Bluray and Wii, disconnect from the network and forget this network.
** Next power off your modem and router, wait 10 minutes and power them back up again, modem first, then the router.
** Once all the right light are steady on both the modem and router, try to connect either the Bluray or Wii to the network and see if you can get Netflix to work. If yes, you are in luck! If no, you may need help from an internet professional or the 1-800 support line of your router manufacturer.

Hope that helps.

It will only need setting up if the EEPROM has been changed and in that case follow the service instructions. Otherwise the main menu will give aspect ration and tuning adjustments.

Take the back off and see if you can see the flat ribbon cables that go into the LCD panel. Apply some pressure on those cables at the place where the line originates from. If that changes the line you know that it is a TAB error. Sometimes applying that pressure is enough to fix it before replacing it.
