Sweet TV had it for about 6 or 7 years. One day the picture started to become fuzzy. It became worse over a few days and has remained fuzzy with inability to even read the menu secondary to fuzzy look. My guess was the tube went out. Any suggestions

Re: 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.

For how many years this TV with you? Most tv now a days after few years of using vertical IC solder started to dry(dry solder) you can try to re-solder or you may check also two capacitors (100uF/35V) for most JVC model has this symptom with this parts changes its electrical characteristics. If still problem persist replace vertical IC. Hope his helps, Good Luck
I own the same model of tv and have owned it for over 1.5 years. I moved with it twice. I had this problem about a month ago. On both vertical sides the screen became very fuzzy, yet the center remained clear. When turning the tv off and on I also noticed very wierd red, green, and blue lines streaming across the screen before the picture comes up or after it fades. I found no solution or cause to the problem. But I had two "long-boy" speakers from my panisonic 5.1 surround sound system setup right next the tv on either side. I set the center channel on top of the tv with the receiver on the shelf below. I thought well maybe some how the speakers were cause some sort problem in the tv. I moved the side "long-boy" speakers from directly next to the tv to about 6" away and removed the center speaker from the top of the tv. After several days of normal use of this configuration, the tv turned like normal and the fuzzy edges were gone. The symptoms lasted for around two weeks, and the several days after I moved my speakers. My only guess is that without a deguassing feature, it took several days for the magnitism to return to normal after repositioning my speakers.
Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .
