Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

Image is streaked and wavvy until set warms up

When I turn on the television, the image is extremely wavy (horizontally) and had bright white streaks flaring more or less vertiaccly. Over the next ten minutes it gradually improves until the image is fine - as good as ever.

Is this fixable? Or is my set dying? It is about five years old but I would like to get another year or two out of it.

    Well, that's cheaper than buying a new televison, I guess. Thank you for your help

    One further question - will it get progressively worse and/or fail completely? Or is this as bad as it is likely to get?

    Thanks again.

    PS - Any chance your shop is in Contra Costa COunty in California.

Ok Good new it is fixable...bad new not cheap. what has happen is that on a cuircit board known as the "hypermodule" there are some capcitors that have failed...these are very small capacitors known a surface mounts. toshiba has a bulletin on this and they will need replaced... these are difficult to replace even for a technician. ideally it would be better to replace the module but these are hard to find. typical repair for my shop runs about 450 to replace the caps...delecate work ..the board can be damaged. and like i said not replacable...

    Your welcome.. i have seen a few of these and i believe they do get worse over time....unfortunattly my shop is in little rock will take longer to clear picture.. i have heard that hd signals or different inputs are better.. i have not confirmed this.. this board processes vidieo signals so it might be true. if you need any more advice ... willie at

Same problem as many others- GREEN TV bought from Circuit city and went green about same time as extended warranty ran out. no blue left in picture green cast over all pictures any options at this date.TV...

Sony has extended the warranty on the optical block regardless of purchase date until 6/30/10. I just had them cover the repair for me. They were very good about it. Call 1-239-768-7547 in US.

Green wavy images on the screen? Convergence is fine but there is a warped green image of everything on the screen.

Projection TV sets have several common problems listed below.

Problem #1) Convergence


  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted
  • No Audio/Video - makes a chirping sound.
