HomeCRT? OK, i work in a tv department selling tv's and today i had to deliver a new set to a customer. the customers old set was the JVC AV-32980 Manufactured in 1998 he didnt tell me whaqt was wrong with it just doesnt turn on so instead of throwing it out i figured i would take it. Now would be possible for the tube to be shot already? that just seems to new of a tv to just go out like that. So i was wondering if anyone would knoow any common problems like this. Please reply, or email me at seprobe96@yahoo.com Thanks

Chris, I've been a monitor technician for 15 years and I can tell you that it is possible for a bad CRT to go bad with seamingly low usage. Although extremely rarely, the guns inside the tube can get shorted, which could cause a power supply shutdown condition. To isolate this problem, pull the CRT neck off the back of the CRT and try to start it up. If you get high voltage and possibly audio, you'll know the tube is bad and you can assume everything else is OK. The only other condition you'll see in a bad CRT is low brightness and/or poor color contrast. And this won't cause the TV to be dead. Hope this helps. |
