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.

Blurry edges


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.

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.

During dark images on my TV, several green lines are visible across the TV.


You may have an arc in the screen and focus circuits. Water may have gotten into these circuits causing a delayed reaction. (Circuits Corroded). These circuits at least part of them are a part of the high voltage transformer (flyback). Your picture tube socket has spark gaps inside of it too which may be arcing. You need to have it checked by a tech to find out just what is arcing. Stargazer

Fuzzy or blurry picture


Ok with you I can skip the "do you have electronics experience?" questions. With 14 years under your belt you are a pro. So here we go. The problem you are experiencing is called blooming/loss of focus this occurs when there is an increase in CRT anode voltage and control of the electron guns (in the CRT) is lost. The result is the picture spreads and focus is affected. The problem can some times be taken care of by adjusting the focus control However if you have auto focus the auto focus circuitry might be the problem. The common parts (areas) to check are as follows: 1) Focus control (to see if the problem can be soled by adjustment) 2) IHVT anode (test to see if voltage is correct you will need a schematic and a high voltage probe) 3) CRT Socket board ( Check to see if the bias voltages and input signals are correct you will need a schematic, multimeter and oscilloscope) These would be the areas to check, I hope that you are seeing my point here. My next bit advise if not one of your experience, you have that, 14 years of it. However, you have little ones and they are your NUMBER ONE concern, So my advice would be to get the set repaired at a TV repair shop. The reason being is because even though I have named some places to start your troubleshooting, TV repair is not an easy thing and there may be other components that could have gone bad and you don't have the time to do investigative troubleshooting. I wish you well on this issue and take care of those little ones. Respectfully Submitted, Shuttle83

I would suggest to unplug the tv from the wall for about 15 minutes and then plug it back in,and turn it on,this should reset the microprocessor and realign the colors back to normal.let Us know how it goes and if you need more help.
