Question about Hitachi 53FDX20B 53" Rear Projection Television

Color convergence "whacked out"/blue shadow to right side

Hi...Have a Hitachi 53FDX20B...manufactured July 2002. Color convergence is going--started to in October...getting worse b the month...blitzes in and out of synch , especially at start up for about 15 minutes...and the Blue color is now always "off" to the right slightly, causing a now permanent blue shadow. Tried the "magic focus" many times...shows either a "4" or "5" after finished, but seems to do very little if anything. Also has a slight "burning electronics" smell coming from the area where the 3 bubs are when first turned on for a few minutes(I took off the bottom back cover to investigate). All 3 bulbs look ok--a little dusty, but ok. Not sure if I need a new amp, new bulbs, both, or something else. Thanks!

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Hitachi 53fdx20b has yellow line on top and bottom an well as blue, all color if off. What is the problem and how much would it cost to get fixed or can I fix it myself?


It sounds like a convergence problem and is typical for many projection sets.

Parts cost would be under 25 dollars.

The repair consists of getting at and replacing two convergence chips and being able to solder is also involved as they have 18 pins each chip.

Let me know your skill level and I would be happy to help.

I have the Hitachi 53FDX20B Manufactured in October 2002. It had the convergence problem where the upper left corner was a mixed up coloring and kind of a wavy line that didnt move. Color correction...


You need to replace both of your convergence ICs STK392-110s
use 120s Mats has them 1-800-628-1118 Check Low ohm resistors near ICs 1.8ohms 3.9ohms 2.7ohms etc... RK48 RK50 RK54 RK58 RK60.
On front of convergence board is a blue contact switch this is how you enter convergence pattern R/G/B to adjust convergence,
you can remove Front bottom panel and see the contact switch from front of TV With TV on Press and release then Pattern should come up. When you call Mats ask if they have Convergence Kit that has ICs and resistors in it!

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.

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 replaced. This is a common problem.

If you don't see a kit for your set send them a quick note and they will put one together for you.
