Re: out of focus

The focus control is on the high voltage transformer. These Zeniths were common to have the CRT's fail and cause a blurry dark picture. If the focus control doesn't do much then your CRT is bad.

Re: out of focus

How old is the set? If picture is really very blurry, Try adjusting 'focus'. You can find this conttrol generally at the rear of the set. Otherwise,. if you know solid state electronics, Check the Focus control on the FBT. It is also possible that the CTR Base is faulty. Replacing this helps.

I have a sony trinitron 36in tv, the screen works fine, colours are all great, no flickering or random shapes at all, its just a little blurry around edges, especially small text, its very blurry and...

it is very easy you just need a very small straight edge screwdriver

you should try to adjust sharpness setting with on screen adjustment first

if tv is too old tube might be going "soft" and sharp focus might not be able to be fully achieved anymore

good luck

no it is not hopeless! if you want to do this procedure I can help you adjust the main screen focus inside the television on the FLYBACK TRANSFORMER but you will need to take it apart unless there are access holes in the back for the adjustment.

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.

JVC AV-32F704 32" TV Picture is blurry - cannot read any writing on the screen

You didn't mention if you saw fine white diagonal lines running through the screen from top to bottom. If so, you likely have a shorted Picture Tube which is not usually fixable. If there are no lines seen running through the screen, then it is possible the High voltage transformer which also has a screen voltage and focus control built in that could be bad. I would expect the cost of that part to be about $100, so the repair cost total could approach that of a new set I would guess.

behind the front grill is a door with 4 t20 torque screws in it, remove that & to the left will be a screen/focus block, three knobs will be for tube intensity STAY AWAY FOM THOSE. the other three will be your focus for each tube
