Those are nice looking tv's. Unfortunately it might be the convergence board IC's that failed. (color alignment controller) This isn't a DIY project, usually cost around $300 a failed IC. You might at least have a technician diagnose it for sure. Then you'll know whether to invest or save up for something new.

My toshiba 65hx81 cut out lastnight. All I have now is the red flashing pwer light. Where do I begin? Do you know what the issue might be? Thankis, Kyle


Frist Kyle count the number of blinks on the set when it shuts down, this is an error code related to the problem area., The most common failure in this model is the deflection power supply board. This board provides high voltage to the picture tubes and related large signal circuits. You may want to check the horizontal output transistor for shorted condition, if it is found to be shorted replace it an the flyback transformer as these two work to gether to produce the horizontal frequency to produce the high voltage.

Red gun convergence problem


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.

I have no picture and my power red light is


Tell all users of this site that the issue you seem to be facing is common in alot of rear projection tvs. When they shut down and the red light flashes, it may need a component known as a large signal board/deflection board for particular model and brand of tv. Ask a technician for more advice. But i believe this is the issue

Sony KDF-E50A12U TV Swith on ok, after about 30 seconds the tv goes into standby mode, green power light on with 3 rapid red flashing lights. Any assistance appreciated


red light flashing means it can't dectect lamp housing. you can try and take it out (door on side of TV to the right hand side) and reinsert. But it probably means your lamp has blown. Replacement xl-2400 lamp is east to replace. Search ebay to buy one (about £100) and youtube has a video showing how to do it.
