Question about Hitachi 53SBX59B 53" Rear Projection Television

1 Answer

Hitachi 53SBX59B model and the pow def board is an AP93/23?

I am replying to your suggestion on the tv for a failed collapsing picture
I have the service manual for this tv with the service schematics and the image of the pow/def board if you can give me diretions from the FBT or some other obvious location I can find it. the verticle output sounds likely as the symptoms began after a move from one home to another, or how is it marked on the Board?
Thank you for your solution I will rate it after I resolder the connections. BTW what causes the values to roll like that bad signal or bad memory ? I can guess why I am missing a hex value in the 1st v line... a bad solder point will drop the value in memory but the rolling one and the picture seems to skip to the left at the top in video chroma adj mode.

I have a 53" Hitachi Rear Projection TV, Everything works except the color. The 3 color projection lamps are functioning and all of the tv's focusing features appear to be functioning as well. It has a...


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.

Convergence not working on my Hitachi 53SBX59B


The board is no longer available. It is much less to just replace the two chips and any resistors bad--give me a email or reply here and I will tell you what is involved.

Total parts cost will be under 30 dollars---usually much less.

I have fixed hundreds of these sets and own two older than yours.

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:

HITACHI 53SBX59B, projection lights don't line up.


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.

Vertical collapse of picture then no picture


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.

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.
