Question about Hitachi 53FDX01B 53" Rear Projection Television

1 Answer

Red horizonal convergence tilts instead of adjusting evenly.

While attempting to adjust the convergence on my Hitachi 53FDX01B the red convergence will align vertically but when I attempt to align it horizontally it tilts from left to right instead of aligning evenly. For example if I press up on the remote to bring the red convergence up, the right side will go up but the left side will go down, this problem is most noticeable on the sides of the screen, when the right side is aligned the left side is completely off of the green and blue convergence lines. I would like to attempt this repair myself as I've had experience with computer repairs, however I've never attempted a TV repair before. Any help or advice is greatly appreciated.

You should be careful as dangerous voltages are there, if red convergence is off a lot likely bad convergence chips. A lot of the chips will either be good when cold or even drift when hot.

Note that this is a older set and the twenty or so surface mounted caps in the digital convergence which store the adjustments may be failing---usually if good convergence when hot.

Fixed more than a few of these sets.

How do i adjust the lights on my hitachi 50gx30ba tv


It sounds like you are having a convergence problem--see attached photos for examples----

If so, with the original remote go into customer menu and select convergence (Some Hitachi sets have a button up front called magic focus--if there engage to see if it helps) in the menu you can also attempt to adjust this--if it will NOT MOVE either up/down or left/right for either red or blue---convergence circuit has a problem.

Let me know what you find.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then yourconvergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • 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.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit fromTvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common 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 around images.

Picture of a set that needs the fluid changed.

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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.

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.

Red convergence not aligning


Did you replace the resistors. If not you should have bought a complete kit from www.TvRepairKits.com instead of just the 150's.

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.
