Jvc lt-42e488 tv won't stay on

Tv wasn't working would come on but screen would shut off and just have sound. I suspected the inverter board was bad. Sure enough, there was a blown fuse on the inverter and some shorted transistors. I could not locate replacement transistors so I ordered a replacement inverter board and installed it. Tv comes up with jvc logo and then shuts down. I checked the power supply board, all fuses good. Found capacitor C9204 (4.7uF 400V) bad and replaced it but results still the same. The tv powers up and then shuts down after a second or two. I have found nothing else wrong with the power supply board so far.

SOURCE: JVC LT-42E488. No picture. JVC logo comes up for a few seconds.

A firmware update might fix it. Call an authorized servicer, explain the symptom.

JVC LT42E488 Color Issue


If you have a flat screen LCD TV then there is NO color tube. Somebody is blowing smoke. Don't deal with him. The main board in conjunction with the screen controller board are the places to look.
