Question about Hitachi 53UDX10B 53" Rear Projection Television

All of a sudden, the complete screen turned red with many horizontal lins from side to side - some straight some curved. We bought it in 2003. What are the options to fix it reasonably?

This problem is call convergence,and it will happen to all DLP tvs again and again throught out the DLP tvs live.U must have soldering tools,solder and know how to do soldering to solved convergence problems.U must replaced 2 STK convergence ICS and some or all it resistors.Tries websites like TvrepairWorld.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for the parts and labors.

When we try to adjust red cross, red adjustment will go side to side but not up and down. Red horizontal line is curved instead of a straight horizontal line. Blue can be adjusted up and down and don't...


Thats the classic sign of failed convergence ICs and resistors. You can get the convergence repair kit for your model at www.tvrepairworld.com the kit contains the parts and the Cd with instructions.

TV turns on with a green screen with curved horizontal lines.


It seems you may have a serious problem with your video board. That's why you are getting those symptoms. It's better if you replace it asap!

Fuzzy screen


I have exactly the same problem with my W880i. Suddenly, one day, out of the blue it went half and half, the right side completely blank(yet still with the back light on - I think - ). And a few months later (now). It suddenly randomly went completely blank - back light definitely on -. It happened today,and I am desperately searching for a solution. If I take the battery out, put it back in, turn it on, I can feel the vibrate, and notice a slight change in colour on the screen. But it stays completely blank, and hasn't changed in hours. So ANY help would be appreciated.

Screen image display distortion


Hello.
What you are reporting is a problem in the pincushion circuit in the horizontal section of your CRT monitor. Usually this is from an electrolytic capacitor that is no longer willing to play nice with all the other components.
It is repairable, but get an estimate first. If the repair bill appears to be around $100, you would be better off to put a few more dollars with that and buy an LCD TFT monitor.
If you are quoted $25 or $30, it is probably worth having repaired. Just keep in mind that these older CRT monitors have age on their components, and once repaired, it will still be an old monitor.
Only you can decide which choice is right for you. At least now you have a few facts to help make the decision.
I hope this helps.

This sounds like your convergence correction amplifiers have malfunctioned. These Integrated Circuits often burn out after a few years (STK392-110) they can be replaced with a higher version (STK392-150) However it is important to have the biasing circuitry checked to make sure nothing has burnt out as a result of the ICs malfunctioning. If you have a background in electronics you can repair this problem with very little effort, however if you do not have a background in electronics, I would suggest that you have your TV serviced by a qualified TV technician.

 

I hope this helps,

 

Thank you,
