    you would be better off calling a tv repairman out and having them fix it.it could be in any of the boards and if you think the tv is worth about 300.00 working then id make the call. there are too many ifs on which board caused the problem

    probably 3 to 4 hundred tops..

We have a projection Toshiba Tv that we bought in 2004 and lately every time you turn on the tv there are lines going through it and you have to hit the touch focus button every time in order for the


Touch focus adjusts at a limited number of places the convergence--next time it does this go into menu with the remote and look for CONVERGENCE in the menu, you will be able to call up a grid of lines or crosses--point here is to see if red or blue are out of position, if so with the remote adjust there and see if it stays when next turned on.

I tell most people with this brand NOT to use the touch focus--it tends to misadjust things and does not SAVE the adjustments it makes---the ones in the customer and hidden tech menu will be saved.

Checking to see if a convergence problem and if so adjusting manually is the first step---may solve your problem and do not keep using the touch focus----its a joke in the repair industry.

I have a 3 year old mitsubishi wd-52526 lcd projector tv that is starting to have some focus/image alignment issues - in general picture is a little out of focus and there are rainbows around things at the...


the differnt guns are out of alignment. Your tv has 3 lcd screens, a red, green and blue one what overlay to form the image. Sometimes they move slightly for what ever reason and that causes the rainbow and out of focus picture. Its something that a trained pro should do but is a cheap fix and won't set you back too much

Hitachi 53UDX10B Magic focus won't focus the green


Hello,

I posted this some time ago, but it is useful to your problem so here it goes:

It sounds like you convergence amplifiers are about to malfunction. If possible can you post a picture of what is happening. Again by the description you gave it sounds like the convergence amplifiers.

If you go to a shop the cost will about $400 - $500 (includes parts and labor).
If you do it yourself the cost will be about $25.00 - $50.00 (includes parts labor is free)

If you choose to do this yourself, here are the basic instructions:
1. Unplug the TV set
2. Take the rear bottom panel off
3. look for a large heat sink with two large black ICs (STK392-110) (6 sided components but rectangular in shape) on it, and remove the board the ICs are on from the TV set.
4. Unsolder the components using a soldering iron and a suction solder remover.
5. disconnect the components (ICs) from the heat sink
6. Unsolder all of the bias resistors and replace them with the proper values (usually 220, 150, 3.3, 2.2, and 3.9 ohms)
7. install the new ICs (STK392-110)
8. solder all connections IC and bias resistors
9. Inspect for shorts
10. reinstall circuit board
11. Plug the TV set in and turn it on.

Remember to check the deflection circuits also

I hope this helps

Thank you,

Hitachi 57SWX20B 3D Effect due to green light convergence problem


I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.

http://home.comcast.net/~leebailey00/Hitachi_DCAM_Manual.pdf

The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

Blue Halo Across screen


Hello Damianian, I too have this hdtv and had problems with the convergance and self-focus within the first year of ownership. I called Samsung within the waranty period and they sent out a tech who replaced the convergance board for free and did the manual convergance in my home. After this, with the new upgraded convergance board installed, the self-focus was not necessary anymore so I turned it off. Some time later the convergance needed done again so I called to get a price on them coming out again to do it. I didn't like the quote they gave me over the phone (around $200.00usd) so I looked for a Service Manual online and found one on an Ebay store for a total of $13.00usd including shipping. I now perform the manual convergence on this set myself and it's easy to do.
Anyone wanting to get a Service Manual for their hdtv or other technical device should check these guy's out. They now have their own website. http://www.thecdguyz.com/
I hope this helps, good luck!

Problem with the picture


You need to replace the convergence ICs in this TV set. If you know how to solder and work on printed circuit boards and can follow a circuit diagram, this should really not be a difficult thing to do. If you do not have ALL of these talents, play it safe and call in a pro to assist you in this repair as this TV set is NOT the place to be experiementing around inside of. Good Luck
