I believe you can order the convergence board replacement for $299 from Part Store, here's a link to it for my 61" Hitachi, which should use the same board:
http://www.partstore.com/Part/Hitachi+Ltd/Hitachi/61SWX12B/Hitachi+Ltd/Hitachi/CS00452R/New.aspx

They offer a 30 day hassle-free return policy, so if for some reason it wouldn't work for you or isn't the right part, all you'd be out is the return shipping, as the initial shipping is free.
I'm in the process of having my board fixed w/the IC/resistor kit and hopefully I don't need a whole new board.  We'll see, but give this a shot, I don't see how you can lose...  -TD

What does it mean when you get a error code 5 when you are doing the magic focus?


Mean ur tv convergence board it is dead,any codes error at all,mean the tv convergence board have components it is dead and the board it just dosen't conververt it three CRTS tv colors Tubes like R,G,B colors lines yokes anymore.Now.The tv convergence board must have it parts replaced like 2 STK convergence ICS and some or all of it resistors too.After the tv fixed it convergence board,the tv will run the entire Magic Focus function,without any error codes at all.The tvs shops will cost u like $300-350 for parts and labors.

I changed the IC chips on my hitachi 53uwx10b tv like you guys said that helped alot but still have wavey lines on both sides of the screen what do I change on the con. board now? Thanks alot Jim


Resistors " RK42 3.3ohms
RK46 1.8ohms RK50 2.7ohms RK54 1.5ohms RK58 3.9ohms RK62 2.2ohms After you replace all of them then enter convergence by pulling OFF bottom front panel there on front of convergence board is a small blue button press it and a convergence pattern will come up now aline each color red then blue.

Convergence settings on hitachi 53uwx10b


Yes - You will need to either remove the circuit board or lift up the tray. If you are not sure how to do it yourself read the link below.

  • This is a very common failure on Projection TV sets.
  • 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 can see some example photos and find a solution here...

Your TV most likely a convergence failure. ( common problem )

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 are some photos of convergence problems.

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 replaced. This is a common problem.

0667c5f.pngSOLUTION

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.

Ineed to know what convergence ic's are in this tv


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.

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos aroundimages.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Check to make sure you reconnected the jumpers to connect the board that you removed. Also, check to make sure no resistors are burning. If still no pix, make sure you reconnected multi pin plug by digital convergence unit (DCU). Next, disconnect conv. plugs marked red, green and blue. This should allow power to come up if chip(s) are bad. Next, check pico fuses on board by jumper connectors or in power supply. If these are open look for solder bridges around conv. amps. Also, if any of these are open check all zener diodes beneath heat sinks where you installed conv. amps. Probably 27 v glass zeners shorted if solder bridges were created when changing chips. Good luck, sometimes you just get a bad I.C,Russmann.

53uwx10b,hitachi


dactag,
Working backwards now.......The burning smell will be the current limiting resistors near and in the circuit of the IC's
you changed..1 to 2 ohms, 1 or 2 watts.....caused by generic
replacement IC's STK392-110,120 or 150......Here is what to do to FixYa! First,please read some of my solutions for convergence
repairs...any brand,the info is generic,the repair parts are not....

1) REMOVE cheap IC's ! Replace with Hitachi part # CZ 01341
upgrade Mfr by Sanyo STK394-160

2)Replace any / all burnt or changed value resistors

3)Re-test to see any symptom....DO NOT CONVERGE

4)Think about putting the original DCU back,since it was
not the problem .......

5) Now where are we at ?? ............................T.

Bad Solder


I don't know if you can buy the boards anymore, ive always replaced the IC checked the resisters, i can point you to two websites that have instructions.
http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html
http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm
i would also replace the IC with the stronger ones stk392-180's and i would replace both no matter what.
