    First of all this is Toshiba 51WH36P model. Are you suggesting capacitors on hyper board and IC on same board or some other area. I have got service manuel, if you can help me to locate the parts and problem, I will be able to solder and replace it. Your help will be appreciated.

I see. If that's the case, an inside component needs replacement like an IC or capacitor. I believe there is a "bulged" capacitor inside. You need to replace that. If you're not familiar with basic soldering/desoldering, have it repaired by a TV technician.

Is there a focus for my F19251GY TV

Yes, of course there it is in every TVs. The focus adjustment in TVs determine the clarity of the display. It is a service adjustement and if you want to adjust it you should open your TV. It can be located at the Line Output Transformer [LOT], and integrated to it.
There will be two adjustable controls can be seen on the LOT. Out of which one is Focus control, and other is Screen control. Both are marked. Normally Focus control is placed on the top side and Screen control to bottom. Both controls are interactive, that is adjusting one will effect the other a little.
If your TV is out of focus, you just open its back cover and locate the said control. It will be usually marked as focus. Adjust a little while looking at picture to get a well defined focus. For this adjustment, take its menu display as reference rather than a moving object. Adjust it to get a well defined display. Place a mirror in front of your TV, so that you can see the image on it from back side.
A defective CRT [picture tube base] "socket" may also be the cause out of focus picture. It can be located on the base card of your TV, and can be detached from it desodered. If the above said adjustments did not give any results, the CRT Base may be defective. If base socket is defective, you can hear a very slght "shhhh" noice from it as you advance the focus control. Try to find out and rectify the problem. Ok

Picture is bluring...especially the writing..

If you are comfortable working inside the set, locate the flyback transformer (part with large red wire coming out the top.) This part should have 2 controls on it. One should be labeled screen and the other focus. Try adjusting the focus control a bit. If that fails to resolve the focus, please update this with the make and model and additional details will be supplied.

Cannot get the set to focus. Colors are blured

Sounds like a convergence misalignment, go into the tv menu and look for other adjustments sub menu and follow the on screen directions,this is a simple procedure but will take a little time to get it adjusted just right. Directions are also on pages 20 and 21 in your owners manual. Good luck!

Picture changes focus/sharpness instantly and then recorrects


You can try and get more infornation for me.

Go into the the menu by pressing the WEGA GATE button on the remote. In the sub menu of picture adjustment switch the DRC-MF setting to off. It should read normal.

See if this stoppes your focus problem.

If it changes let me know for further directions.

Cam blured

look and see if there is a way to adjust the focus on the camera. On some logitech cameras that center lens piece can rotate, allowing you to change the focus.

Blured viewfinder

Look at the viewfinder on the camera.

Now look on the LEFT side of the viewfinder; just above the swivel-screen.

You will see a little thumb wheel there.

That is the focus for the viewfinder. Move it up and down to bring the viewfinder into focus. (Don't forget to do this while you are looking through the viewfinder so you can see what you are adjusting.)

Easy fix. :)

*** I have to configure Colors with each power on. ***

The six controls you appear to be adjusting are the screen and focus controls for each of the three picture tubes. These usually only have to be adjusted as each picture tube ages or when replaced. You may either have a defective "focus block" i.e. the black box you have been adjusting, or the CRT's themselves may be going bad at this age. You will probably be money ahead to just replace the TV with a new HDTV set. At 13 years old, it shouldn't have much life left in it anyhow.
