Question about JVC AV-27F803 27" TV
My brightness or screen color dilemma is different than those posted. After viewing the tv for a short time, the screen will immediately turn dark. It doesn't slowly fade to this condition, but goes from normal brightness to dark rather quickly. Current Conditions: satellite (dish network) Components not used full time: Monster Power Center HTS 3500 Denon Receiver AVR 3805 TV is not directly hooked up to either the Power center or the receiver. It has an Independent outlet.
I likely you have a loose conection in the crt board at the neck of the picture tube or a loose conection close to the high voltage transformer,I would suggest to tap the main board as well as the crt board with a wooden or rubber handle(not metal),be attentive were you tap to see if the set reacts ,if the set reacts you will need to resolder those places ,be carefull working on a set that is on while you do it,this should give some idea what the problem could be in case you want to call someone to help you with the repair.Let Us know if you need more information.
