Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

Red duplicate image outline of picture.

I just got this TV from a family member. I hooked it up and it worked great. Two weeks later I returned to my apartment and it looked like I took my 3-D glasses off during a 3-D movie. I tried the auto focus and the red light plus sign will not line up with the blue and green light. I know that it is probably a convergence thing, but is there any easy way to fix the light. The closest repair place to me is an hour away. I had to rent a trailer to get it to my apartment. Any ideas would be much appreciated. Thank you!

    Thanks for the quick response. I can move the blue crosses in all directions and when I auto focus, they line up with the green crosses without a problem. I can not move the red crosses at all. Thanks again for the help.

    I looked at my TV again last night and the red crosses do move vertically. So the problem is that the red crosses will not move horizontal. Does this change your prognosis?

You have lost red convergence. which ussally means one or both of the convergence amps need to be replace.. but it could be a resistor. does the red cross move up or down or side to side. how about the blue does it move in eather direction. this will let me know if both are bad

    this to me indicates bad convergence ic...maybe just one. if i was troubleshooting this set i would say i would need to check this chip. ussally you replace both.. depending on set convergence chips can be difficult to replace. lot of soldering so i would let a qualified tech look at it

  • Willie Howell Jan 04, 2008

    O yes.. this now points me toward one of the convergence ouput ic "RESISTORS" are bad. theres resistor for veritical and horizontal.

Sand shooting back in pool


If you took "Pump" apart, you wouldn't have found broken laterals. You will need to open up the "Filter" to find laterals. If sand is ending up in the pool, you either have a broken component within the filter or you have an overfilled filter tank and during backwash sand is lifted up into the valve, and upon returning valve position back to "Filter" the residual is blown back to pool via the return inlet. If this is the case that is why always follow label / owners manual directions as to Quantity of media to add. More is not necessarily always better!

I am having so many money problems in my family what i want to do? money problems we get credit from so many members now we cant able to return it and we dont have any source to return dont know what to do


I wonder why this is listed under the SHAVER catagory, but oh well..... Money problems are affecting the entire world, and they have/will forever.... If you are finding yourself too much in debt with family members and friends, you need to look at the spending that you are doing. If fast food or take out, you need to buy groceries and cook, much cheaper. Also, cable TV, no no, cancel it and just use regular programming. Electricity, make sure ALL items not in use are unplugged, it can save a lot, trust me. There are many things to do, but to pay back the family, you need to also work on your income. Perhaps even being a helper right here online! There are opportunities all over the place, eBay and the like..... Good luck!! Guy

Light green and pink spots on my hd tv!!!


Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.
