Any hope for this TV
Would someone have a look at this TV screen. The fix could be easy but
beyond me right now. http://www.islandnet.com/~roger/TVmonitor.html Roger |

Maybe, maybe not.
If the failure is in the degauss circuit or due to a big magnet being too close to the tv, relatively simple fix with the right tools and training. If the tv was dropped and the shadow mask was damaged, it needs a new picture tube to correct the problem. If the yoke has shifted or someone screwed with the yoke adjustments, only time needed by someone with the experience and training to do the adjustments with the proper test signal generator.

The set may have been dropped, and the mask in the tube was damaged.
The degaussing coil is not working properly. The CRT was exposed to a strong magnet and requires a proper degaussing. The deflection yoke, and purity magnets may be out of alignment. This also means a full convergence alignment. Because I can see some rings or curved lines (looks like Newton Rings), from experience when I have seen these, it was usually the mask in the CRT that was damaged. -- Greetings, Jerry Greenberg GLG Technologies GLG ========================================= WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm ========================================= "Roger" wrote in message ...

Well, I sought out the previous owner and she says it was dropped. Dang!
But I know more now anyway. Thanks for the help Roger In article , "David" wrote: Maybe, maybe not.
