Question about Toshiba 65HX81 65" Rear Projection Television

Toshiba 65HX81 No Power Issue

TV worked great then all of a sudden no video or audio(black screen). Press Power button and light turns red and you here a click in the rear of the tv and then nothing. I am not getting any blinking like others have commented on and I have checked all of the fuses that I can find. I am still searching for schematics. I have looked over the boards and don't see anything fried at all. Any help or suggestions would be very much appreciated.

    I am trying to find the fuses in my 65hx81 toshiba. fuses f889 f890 and f891 but I dont know how to find, check or replace. Please help me. PLEASE. I was told because my left side speaker has blown ( the speaker itself does work, I took it out to make sure, but the tv will not power it.) and I was told I need to check these fuses.

Red light blinking and no picture on Toshiba Model 65HX81 how do we fix?


Red power light blinking is shutdown--protective mode.

Before buying a remote I would see what is wrong with set.

The most common reason on this model is a short in the convergence circuit--uses two chips----method to see if they are shorted is to locate (not real easy on this model) and unsolder all 18 pins on each chip--if set turns on then(will look bad) one of the chips is gone and both need replacement.

The other issue this set has is bad Hyper boards that cause noise when cold and operate after warmup---more expensive to fix than a convergence problem.

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.

Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck

TV is not powering up and red light keeps flashing


I had the same red blinking led problem on my Toshiba Theaterview tv. I resolved by:
- Unplugging the tv.
- Press several times (3 or 4 times) the tv Power button.
- Plug the tv back in and press the Power button once to turn the tv on....tv worked!!!

I've had the problem before and tried unplugging the tv for a couple of days and that had also worked, but I this recent solution seems to be faster.
Good luck!
