Question about Toshiba 57HX81 57" Rear Projection Television

1 Answer

Toshiba 57HX81 is all wiggly and distorted (youtube video attached)

I got a free Toshiba 57HX81 off Craigslist. The tv turns on and the sound is perfect, but the image is all scribbly and wavey. After about 30 minutes the picture gets a little more clear, but is still terrible. Plus there is a white line going down the side(s) of the screen.

    All connections look bad, composite, coaxil, they all have the same problem. Do I need to replace the hyper board? :(

  • muleltgames Jun 16, 2008

    messed what up exactly? The guy I got it from said he transported it in a uhaul and when they unloaded it and plugged it in it started doing that.

  • muleltgames Jun 16, 2008

    Which connectors? Please be as specific as possible. I can solder well, but I need to know EXACTLY what it is you think I need to resolder. What connectors?

  • muleltgames Jun 16, 2008

    The thing is, is that even when NOTHING is plugged in, I can see even the default tv snow is distorted with this problem. Does that still mean it can be the connectors?

    That looks like a video game you are playing. How is the video game connected to the back of the TV?

I don't know about that. Someone probably was rough with it and messed them up. You should have a technician look at it.

    The connectors in the back are shorted. It cold be as simple as soldering them back in.

    The connectors the TV plugs into. It would be your coax and AV connectors. See it they are shorted. If your good with a solder iron you might be able to reattach them.



    Good luck on that.

    Yikes! You should get a technician to look at it. It could be a number of things wrong with it.



    Someone needs to look at to fix the problem the right way.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

As with all products that contain a digital display, in rare instances, when viewing certain content (e.g.. television broadcasts, video games, DVD), you may notice that the sound and picture are slightly out of sync. This phenomenon can be caused by various factors including, without limitation, video processing within the TV, video processing in an attached gaming system, and video processing/different compression rates used by broadcasters in their programming. You may want to try one or more of the following suggestions, which may help to reduce the effect of this phenomenon:
  • If the TV is connected to an external A/V device (e.g., DVD player, video game system, set-top-box, etc.) always try to use the Color Stream video jacks and corresponding audio jacks or the HDMI input (if available on your TV) for connection to such external A/V device.

  • If the TV is connected to an A/V receiver that has a programmable audio delay feature, use this feature to help synchronize the sound to the picture.

  • If connected to a video game system and your TV has the Game Mode feature (see owner's manual for more information), enable this feature.

  • If you notice this phenomenon only on certain TV channels, please contact your local broadcast, cable, or satellite provider to inform them of this issue.

Toshiba 57hx81 tv has a bow at bottom of screen and blue in color tried using toush focus & got error then tried to focus manually & couldn't get the bottom lines to focus all the way down


noted in the owners manual, if auto focus returns message "error" , it suggests to use manual convergence setting..failing that, is it resonable to suspect that the STK-392-110 (convergence (2)chips)are beginning to fail, bendt horizonital lines is the effect. you can check all the resistors and pico fuses (power board)near the chips for shorts, chances are they are ok. seeing that there is somewhat of a picture (kinda like 3-d). i would repaired it!.. while your there do the hyperboard repair as well by replacing the 10 caps with 16v@10uf. (causing a wavy vertical distortion effect).

Toshiba 57HX81: Green works but Blue and Red seem to be out.


Do you still have reds? Is the image still clear though discolored? If so you ought to replace the blue bulb which has most likely failed. The part no for the 57HX81 model blue CRT bulb is TOSHIBA     23008753.

57H81 projection tv has very wiggly picture.


This is the Hyper Module that needs repaired. There are several small sm caps that dry out in this model. It's the module standing up to the right covered by a can as we call it. I really don.t recommend you trying to repair it. One slip and that module is done and you can't by a new or rebuilt one anymore. Please let a repair center look at it and do the work. You won't regret it.
