    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.

How do you adjust the focus


The flyback transformer located in the rear of the tv, might have to take back off( usually some have holes to adjust from back). There will be two potentiometers on the back of the flyback. Top one is screen, bottom one is focus. Put a mirror in front of tv and adjust the focus potentiometer.

Is there a focus for my F19251GY TV


Hello
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

I have a Toshiba 65H82 and at first the picture was blurry but would clear up after about 10 mins now the picture just stays blurry. Can you tell me what the problem could be and if it is worth fixing it?...


Hi,
Try adjusting the focus block this requires opening the back and front bezel of the TV. If it doesn't clear up after adjustment attempts then the liquid coolant inside each of the tubes need to be emptied and refilled with new coolant. Over time the coolant gets cloudy and can cause a blurry image with a white sheen. Contact me at the link below so I can help you further.....if this helps please rate:-)

Thank you:-)

Samsung Projection HDTV BLURRY!


Each projection set has focus controls in back, usually they don't move or go out of focus unless someone moves it, but in your case if you open the back you will see a focus block with 6 knobs 3 are for screen,I would highly recommend that you don't move this. Look for the focus and you will have to set each with the one color. Cover the other two and adjust.

*** 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.
