what camera model are you using? Is it possible that the auto focus is turned to manual?

No easy way short of monitoring with a scope and or voltmeter, based on age of set I would first "look" at all the filter caps in the main power supply--bad ones when they get hot can regain some function:

Check the filter capacitor to the supply to video output card. You can locate this capacitor at the CRT base card to your Sony Trinitron. Replace this electrolytic capacitor.

Hi,

Below are some troubleshooting tips for a TV that has a fuzzy or blurry picture;

If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It's worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.

Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.

Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.

Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.

Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.

If your TV has digital noise reduction, try turning that feature on.

You can adjust your TV's sharpness and picture modes to see if that improves picture quality.

Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.

Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.

Let me know if the above helps or not, so that I can direct you further on what do next.....

Best regards.

unfortunately these newer tvs do not display the standard definition analog channels very well. the picture gets better when viewing digital channels but doesnt display at its best untill u place it on a high definition channel

Ur convergence is dead.U know how to solder?Tries this website. Tv Repair World.com buy the convergence kit,and replace it.

Make sure your zoom is not set to low also switch on the antishake in the camera menu.

Turn picture quality down slightly to either 6 or even 5mp ( I know whats the oint in a 8mp if you are going to turn it down) believe me it works better.

Fuzzy is a funny word. I never use it to describe a picture problem. That because fuzzy can go too many different ways. There is snowy fuzzy, blurry fuzzy, grainy fuzzy, and demodulated fuzzy. If the set goes out of focus intermittently that has something to do with the focus ciruitry. If it goes grainy that is a front end problem, usually tuner related. The other types of fuzzy are generally associated with problems in video processing some where. So, which is it?

Oh, and BTW that unit has three small picture tubes in it, one red, one blue, and one green. It doesn't have a 'bulb'.

This is the classic symptom of a CRT (picture tube)that is starting do get weak. The picture takes longer and longer to come on, it appears greenish and blurry, and it blinks on and off in different scenes, and when it is off the timer LED blinks 5 times. Sony has a circuit called "IK Blanking" which monitors and adjusts the colors in the picture tube, and shuts the picture off when the tube is getting too weak. The good news is that the Sony tubes always respond beautifully to a CRT rejuvination (recharge), and the picture returns to perfect. Since the set is 36 inches and VERY heavy, it should be serviced in-house and an appropriate charge for a service call for your set should be around $150.
