Question about Hitachi 43FDX01B TV

1 Answer

Your solution There isn't an adjustment that will 'shorten' the picture? I had the convergence problem repaired by a repairman, I think he replaced the red gun, but it came backwith this 'scroll off the screen' problem. 2 weeks later the repairman and his business closed and my problem persists and I was hoping it was a simple fix. The picture is great just a little too tall..

Having i think convegence board problems with my phillips model # 60pp9202/17F called tv repair guy said it was my convergence ..colors are alll orange and bottom of picture kinda bubbles up can i replace...


Replacing the convergence board will require a complete convergence adjustment. A better solution would be the replacing of the defective convergence IC. This would retain the convergence settings for the set. I'll locate the part numbers and costs and update this later.

The convergence red and green colors are bleeding into the picture. On the bottom of the screen and on the left side of the screen. I tried to readjust the convergence factory settings and the problem...


Hi


Thanks for using FixYa.This is often caused by failed convergence ICs. I don’t think the issue is with the power supply of the unit as the sound is coming fine from the unit. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs (STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. There are
repair kitsavailable which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

Hi I have a toshiba 50h82 tv that is 7 years old with a convergence problem with the red and green lines that is going to cost $400 to fix but now that I am thinking about it before the convergence problem...


You are describing 2 different problems. The convergence problem can be fixed by either resoldering the convergence ICs or replacing them. These ICs cost about $25 each and there are 2. I suspect that the $4oo is for replacing the convergence board. This should not be necessary as the board can be fixed. Also, the brightness problem can be dirty CRTs, dirty mirror or faulty coolant fluid on the CRTs. If the picture was good prior to the convergence problem, the set is probably worth the repair if you can get the board fixed. While the board is being repaired, the service shop should be able to tell whether or not the brightness can be adjusted.

Convergence is off in the lower right and upper left corner


The repair isn't too complicated if you're comfortable working with a soldering iron. Sounds like one of the "guns" is shot. The chips that need replacing are attached to the heatsink on the convergence board. The reason for replacing both chips is if you're going to bother to take the board out and replace one bad chip, that is the best time to replace the other older chip. The link below is to step by step instructions including pictures of the repair. You can check it out to see if you want to try it. If not, the repair is expensive (between 250-400) depending on the repairman. Best of luck with your convergence problem.

Partial convergence problem


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip 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 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 need to replace the convergence chips and convergence resistors. 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.


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.

Convergence On Panasonic PT-47WX54j


You dont need codes for the service menu you need to repair the convergence circuit. If the lines wont line up in the customer menu they wont line up in the service menu either. Do you know how to solder? If so we can fix this yourself with a little instruction. Otherwise you will need to call a repairman. A good repairman will run you $300-$500 depending on your area. Let me know what you want to do.
