Hitachi 53sbx59b horizontal wave lines

Hi I usually answer questions on this forum in the lcd section but i picked up this Hitachi 53SBX59B and the interior components seem in good condition. I get a image on the screen IE vid 1 for about 10 seconds then the picture collapses to a series of horizontal wave lines across the screen(red blue green) I am thinking the high voltage p/s may be bad, all the main projection tubes seem to be working but very low intensity at thier bases. I am used to seeing more light than they are giving off. Magic focus just causes the waves to flashe on and off and after the magic focus for the convergence is done it just has wavy horizontal colors across the screen again all green led's are lit inside on the second board and I have air cleaned the inside out so the dust is gone. no evidence of bad or blown caps
let me know what you think and if i can do a little testing on output of the high voltage unit tell me how to check it and i will get back to you with numbers
thanks

I would check the main power supply for a bad filter cap. That could cause the wavy lines. The different colors are probably a problem with the convergence circuit. Try resoldering the convergence ICs first. If that does not resolve it replace the ICs. Also check for low valued resistors in that same circuit or pico fuses.

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.

I have a hitachi 53sbx59b 53in tv


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
You can see some examples and find a fix here...

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.

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.

Call the 800 number with the new remote. Sometimes they will have additional codes. Or with the instructions with the new remote you can manually get it to work. You must follow instructions carefully. Look for this section in the instruction booklet
