JVC AV-36D203 TV... blurry picture... help!
I have a JVC AV-36D203... It's a 36" ... had it for just over 3 years now.
The online manual (http://books.jvcservice.com/download...0397/28259.pdf) did not help. The picture is most blurry in the center. Towards the bottom and sides, it is not as blurry. I noticed it a little a couple of days ago, but now it is just completely overtaken the screen. Changing some tint/color settings didn't do much good. My dad blames it on the video games, but it's not a projection TV... I say we got a lemon; the tubes are probably burnt out or something. Any help is appreciated, thanks. |

JVC AV-36D203 TV... blurry picture... help!
Sorry, I've done some researching and found a more appropriate term would be
"poor focus". From what I saw, that is commonly adjustment and picture tube? Is that correct? Any further suggestions? What is adjustment? Would it be worth it to get a replacement tube, and is that something I can install myself? "Lori" wrote in message . net... I have a JVC AV-36D203... It's a 36" ... had it for just over 3 years now.

No, it a tube is not something you will be able to install yourself in that
set. Even if you had all the required test equipment and experience to perform the alignments after replacing the tube, there is no way you would be able to lift and install the tube yourself safely. Since it happened more or less suddenly, the set needs a proper diagnosis by someone with the experience to properly and safely troublshoot the voltages and circuits involved. It is very possible there is a circuit failure in the high voltage or divider section causing the problems. In that size of set it also could have a dynamic focus circuit as well which could have failed components. David Lori wrote in message . net...

Thank you very much!
Another note, the TV was off all night, so now it looks better. Once it's on a while I expect it will get worse. Don't know if that makes a difference. "David" wrote in message ...

Lori:
Probably not a "tube" problem (which is good because tube replacement is cost prohibitive) but more than likely there is a circuitry failure or a heat-intermittent component...... an experienced tech with the proper test equipment and troubleshooting procedures should be able to repair the problem...... or at the very least you should obtain a repair cost estimate so you can make an intelligent repair decision. -- Best Regards, Daniel Sofie Electronics Supply & Repair ---------------------------- "Lori" wrote in message Thank you very much!
