20 Most Recent Hitachi 43UWX10B 43" Rear Projection Television Questions & Answers


You can buy replacements online. Try www.partstore.com

You can remove the screen yourself, actually, on a lot of these sets, it just means lots of unscrewing to open the cabinet and get it out. If only one layer of your screen is cracked, it will be a lot cheaper. And if only the protective covering is cracked, I'd just throw it away and not worry about replacing it. That sparkly colored effect you see on white colors on the picture? That's the screen protector. Some people remove it for aesthetics.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

You hear about fiber optic cables whenever people talk about the telephone system, the cable TV system or the Internet. Fiber-optic lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. They are also used in medical imaging and mechanical engineering inspection.

In this article, we will show you how these tiny strands of glass transmit light and the fascinating way that these strands are made. Fiber Optic Patch Cables

The two STK CONVERGENCE CHIPS AND ANY BAD RESISTORS AROUND THEM WOULD HAVE TO BE REPLACED.

Typical cost for all the parts on EBAY or Suburban Electronics would be under $25.

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 your convergence 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.
Below are two of the most common problems encountered with projection TV sets.

Problem #1 - CONVERGENCE PROBLEM

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 your convergence is broken and needs to be repaired.

This is a very common failure on Projection TV sets and a fairly simple DIY fix.

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 - TV may also make a chirping noise.
Here are some photos of convergence problems.








Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

CONVERGENCE SOLUTIONYou will need to replace the convergence chips and possibly some convergence resistors and pico fuses.

This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from TvRepairKits.com

Their kits include a step by step instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection 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 video.

Pic of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

BEFORE



Set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

Solution #2 - CRT FLUID FIX

Remove all batteries from your remotes. Unplug the unit for several minutes. Plug unit in and use the controls on the set to turn it on and adjust the volume. This will eliminate the remotes. They could have a button stuck. If this does not work you may have a legitimate problem and need a tech.

The set will need a digital box to receive digital channels as it does not have a digital tuner in it--it is a very good set.
