1 Answer

Vertical collapse of picture then no picture

Hitachi 53SBX59B Rear projection tv .
the unit powered up once and I took it into video chroma adjust mode
several values were not at the specified factory settings so I reset them to the service manuals specs, however on pg 6 the 1st line after v only had 1 hex value not two like in the service manual, also in pg 4 or 5 I cant remember, the first value on the hex set was rolling it would not stop maybe dc tc point, after setting these as best I could and setting the rest to factory specs the tv worked for a short time but the vertical height was not stable and was slowly collapsing (falling down the screen) , after a few min the screeen collapsed into an eye shaped collage of colors then the tv lost picture then came back then off etc a few times . now it will not display any image at all. any ideas would be appriciated is this a problem on the pow/def board or the signal board? I can get both replaced but I only need one I think. thanks

You most likely don't need to replace a board. You should solder the bottom of the vertical output, it probably has bad connections. If you don't know where the vertical output is, give me a model number and i will give you a location, or take a picture of the deflection board and i will circle it.

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.

This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.
  • 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.
  • No Audio / No Video - Makes Chirping Sounds

My mirror is broke in my big screen do you have to buy a special mirror or can you use any mirror?


The mirrors are specific to the unit as they have slight curves to bend the picture correctly so it aligns to the screen properly. To ensure you get the correct picture for your unit, you would have to order the manufactures original replacement part. You can order an new OEM replacement mirror for this model (53SBX59B) from a major Hitachi parts distributor at the link below:

It sounds like bad solder connections in the convergence output circuit. It may also be an intermittant convergence output ic which will need to be replaced.

Digital Compatibility


TVs, VCRs, DVD players, camcorders and video games will continue to work, even if they are only analog-capable. Such equipment, however, may not provide digital-quality picture and sound.
Hope this helps.

Picture flickers when T.V. is tapped on or struck.


sounds very much like a loose connection, i.e. a wire or solder joint, you could have a look around make sure everything is plugged in right, as for the solder joints id advise getting it proffessionally looked at as these rear projection tvs can be a lot of hassle if you slighty knock any of the 3 tubes,
