Ok I have a Sony FD Trinitron Wega KV-36HS500 HDTV. It is a 36 inch. Today after coming home from class, I turned it on, and there were distorted colors near the right hand edge of the screen. Oh it must just be this channel. So I changed channels, and it was still there. Must be the dish, so I tried my xbox. Still there. HmmmmOk, so maybe its magnectic buildup, ive heard some stuff about that(whatever that is.) So I unplugged the Tv from the electrical socket, and plugged it back in. I turned it on, and the distorted colors near the edge were gone.
My question is. What was this that occured? Should it be occuring? Is my tv busted? Did the quality of the tv and picture degrade from this occurance? Is my tv faulty?Thanks
What should I do. This is the first time this has occured.
Should I be cashing in on my warranty? Or is this normal? Thanks
Follow Ups:
Does your Sony Auto Degauss on power up? Some do, This Demagnetization would cure the color distortion. If you place an unshielded speaker close to a CRT monitor the same thing will occur. But how did the problem get there in the first place? Any magnetic field could cause it...
Yes its caused by a huge speaker. I am gonna have to rearrange room, so that I can put speakers farther away. Could the speaker have damaged the TV or ruined quality. Thanks
If you move your speakers their stereo effecct could well be compromised.There is another alternative to moving your speakers but it will entail some effort (DIY) & small expense. you could shield the ofending speaker drivers using Texas Instruments Shield Material (available from Percy). This comes in sheet form of varying thicknesses and in 12" widths. TI claims that the material blocks > 95% of both RFI & EMI [Electro Magnatic Interference i.e. magnetic flux). It's the EMI that's causing your problem. The material is very easy to work with using aircraft-type tin snips (serrated cutting jaws that don't slip) to cut to required sizes.
You'll have to open your speaker cabinets to install the shielding. It's most likely only the woofers that are causing the problem (large magnets). Form a tube for each magnet that has a closed end for each woofer and attach it to the speaker basket(RTV cement should work well). It would also help to ground the shields in order to drain off the RFI/EMI.
Happy video'ing !
Hi: It can be fixed, with a Degaussing coil. "In the old days" it would happen and the TV repair man would come by and fix it. Nothing permanent has happened although it is a pain. As suggested, you need to check that your autodegauss works, once you get the speaker moved.
