If the screen is out of focus this is likely due to a defective fly-back transformer, or focus control circuitry.

Fuzzy picture


Sounds like an AGC [Automatic Gain Control] problem with its video IF stage circuit. Contact any service technician, or service center. This is not a user repairable fault.

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.

The picture quality is fuzzy at the lower left of the screen. Also, the DVD picture is off center. How can I adjust or reset both?


Hello,
This indicates an Automatic Gain Control (AGC) problem often caused by a dried up capacitor. You will probably need a schematic to go much further. This could be a problem in the tuner, IF, or video amplifiers.

The following assumes you are sure the signal source is strong - try a VCR or other local one (channel 3/4, not the RCA jacks).

Most of the time the range of AGC is from 1 to 7 volts. If you can get a decent snow free picture with an external AGC source, then the tuner is probably OK.

When using cable input video is good but sound has fuzzy static


Your TVs tuner tuned a little off frequency. It could be as simple as having cable box on where you have good picture but fuzzy sound, use the TVs remote to change the channel and then change it back to proper channel. If that doesn't fix you may have wrong tuning type selected in channel set up menu.

Fuzzy Picture


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'.

Philips 34pw9818 fuzzy screen


Inside the set you should see a large part with a red wire coming out the top. That is the flyback transformer. There will be 1 or 2 controls on the back of it. One should be labeled screen and one focus. Carefully adjust the focus one until the picture is again in focus. Please note that in that area are high voltages (33,000V) that can be dangerous. Be careful where you touch. IT is best to have a mirror so you can see the picture while adjusting the focus control.

One channel fuzzy


Tis is an ongoing problem I seen increase alot over the past few months. From what I can gather, all the channels being broadcast over going from the analog to digital, there's no big suprise to anyone. However, the change from analog to digital is changing at a faster rate, so when you look at the TV some channels will be fine and others will have grey lines, fuzzy picture. The only solution-you need a TV with some kind of digital tuner. On the TV itself if the (TV has one) it will say "SD" or "ED" which stands for standard digital or enhanced digital.
