You probably just have dust build up on the lenses. You can remove the lower back (with the set unplugged) and once you have that done you now have access to clean the lenses using a soft cloth and wipe them down. Don't adjust the lenses as you will spend more time correcting a problem that you create by doing so. Good luck..

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

Picture is blurry, out of color and the letters on tv look like 3D

If you can`t adjust your convergence via the menu then you have a faulty digital and/or analog convergence board

I need a copy of the schematics for my 9-inch color TV so my husband can fix it.

Well you need to look at the manufacture for this as we do not have diagrams here for TV as there old the newer ones I can find but the older oneswe do not have copies anymore due to the digital conversion.

Sony KP-53HS10 - Green & pink halos & picture "bowed" on edges

you will need to replace the convergence IC's and test resistors on them for bad values , if you want to do the repair yourself
otherwise to have a tech come out and do the repair will be about $300

Hello paulaspec,

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):


1) turn color and tint fully counter clockwise until you have a black and white picture.


2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray


3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.


4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.


5) adjust the focus screen and control grids to match the ones on the schematic diagram


6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.


This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.


However if you do not have a background in electronics please take the TV to a shop for repairs.


I hope this helps,

Thank you,

Sony TV with blurry picture

blurry picture is mainly due to focusing voltage is not proper. solution 1 check & adjust focus control on flyback. 2 check crt base for loose. 3 wire going to focus control on crt base got disconnected due to foreign materials deposit on it. 4 if tv is old possibility of crt getting weak.

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.

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.
