Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaHitachi 61udx10b picture problem - 2c07611.pngs a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

I have a hitachi 50 in rear projection tv and i am getting a yellow circle through out the middle of the screen what do you think that is and how do i fix it?


I looked back and see your talking about a crt type. My bad. A small yellow spot is most likely dirt or a bug in the blue optics. Tale the front off the set and with the tv on look down into the lenses. If you see a blob of dirt or a bug this is your trouble. Be careful not to move the blue tube but take the lens assembly off and clean the surfaces. There are four screw that hold just the lens assembly. The other screws shouldn't be touched. It will need alignment otherwise.

Blue blob


Hello rivas_gab. Before I answeryour question let me explain a little how your tv works. You TV uses is a 3LCDtv that gets its picture from a lamp, the lamp produces a white light brighterthan the sun, the light goes through a square prism and is split 3 ways, eachgoing through a small LCD chip (blue, red & green). Then it travels troughthe light engine where the final picture is produced. The blue blobthat appears on the screen might be caused by one or two lcd chips that havestarted to get burn by the intense heat emitted from the light of the lamp. If that is theproblem you’ll have to replace the entire light engine, the other option isthat you buy the prism with the lcd chips, how ever that almost impossible becausenobody that I know sells them separately. If you decide tobuy, search buy part number, NOT model number, otherwise you’ll run the risk ofgetting non compatible parts. If you’re lookinga place to purchase look for dedicated tv part distributors (my personal recommendation:Discount-Merchant ). Happyhunting.

I would check for burnt resistors as the 150s are interchangeable with the 110s however in alot of hitachis I have seen resistors blow after upgradeing to the higher wattage ICs. I Usually switch out the convergence resistors whenever I go to a higher wattage IC just to be sure. If you need more help let me know.
