Hitachi 50FX20B convergence problem

Hello,
Please replace convergence output chips in tv to solve the problem. It requires good soldering skills/ expertise and click to buy convergence repair kit for this tv that has all required parts and instructions.
Hope this will help.
Thanks.

Xpertis,
When the convergence will not adjust after you know you have set them correctly using your TV's convergence adjustment, your convergence board went bad. You can either repair it yourself with kits sold online (links below) but unless you know how to solder very well, opt for a repair guy. Your model will cost between $350 and $450 if you hire someone.

If you like to tinker but not dwell into the soldering world, try finding the same model for free or dirt cheap on a web site like www.craigslist.org that still works but like where a kid jumped into the screen!, and swap out the board.

Good Luck!

Your convergence Integrated Circuits (IC) are going bad which is a common problem for all Projections no matter what brand. Can be fixed by your local repair shop for no more then $250.00

1 watt,Service Manual I have says RK42 3.3ohms RK46 1.8ohms RK50 2.7 RK54 1.5 RK58 3.9 RK62 2.2

U have convergence prob.it dead.Tries these websites.Tv Repair World.com,Ebay.com to buy a convergence kit,repair what in that kit.U know how to solder right?

The convergence amp IC's are bad (STK 392-110) Replace with the Sanyo Type STK 392-120. Also check for burned resistors in that same circuit. Check them with an ohm meter to be sure because sometimes they look OK by appearance .

Your TV most likely has a problem in the convergence circuits. ( 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.

SOLUTION

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.

You need to change convergence amplifiers. Should be no problem for a professional

convergance iC needs to be replaced.
