Intermittant issues are always the hardest to troubleshoot. It could be a loose connection or a component that breaks down under load or thermally.

My JVC model AV-20F476 has a black-out box that covers most of the bottom half of the screen.

Go into menu and under CLOSED CAPTIONS look to see if TEXT is engaged---if it is set to text 1 turn it off or to text 2,3,4, etc

Text was a feature never really used but it is there, some cable boxes also have this setting/feature.

Let me know if you have questions.

JVC AV-36D502: Input #3 doesn't work

Good day sir, its a different issue, about the capacitor, for as long as your replacement part is correct, it will work, now, there are several things you should check, the I/O device that controls the inputs of the TV, usually an IC, check your schematic diagram to trace the fault. check also the line from the input 3 to the controller IC on your diagram. Measure the voltage across the IC Vcc to ground if the IC is getting the right power, Low voltage can be cause by faulty capacitors, on the power supply line, or the IC itself is faulty, Circuit analysis and voltage measurements are needed to trace the faulty part. hope this helps thanks.

JVC AV-32F702 Color TV shuts off after I power it on.

Any malfunction associated with a flashing light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.
