Question about JVC AV-27D302 27" TV
I have a jvc av-27d302 tv . it turns on with picture and the volume goes to the maximum. You cannot change channels or volume. I open the casing and see one board inside that looks to have all the controls. Is there a need for a repair manual??? If I change the circuit board will the remote control still work ?? Are there any adjustment to be done.???
The fault may be the control panel, or it may be in the uPC itself.
Most of the time, it is some of the switches on the control panel.
The most common cause of this type of failure is that many times when people clean the TV set, they spray cleaner directly on the screen or the set. The liquid runs down in to the set and causes damage. Sometimes the damage can be very expensive!
If the fault is just the control panel board, this can be easily replaced. You can order one from the manufacture's parts department or from one of their parts distributors.
You will need the service manual, a scope, and a DVM to troubleshoot the problem if it is more involved than just changing the panel. The only way to know is to try the panel unless you have a way to test it.
