Question about JVC AV-20920 20" TV
I have no picture or sound only the red timer light blinking. I tried unplugging the tv for awhile but it did not help.
You probably have one or two diodes bad which would have to be unsoldered to replace. Since it is a small TV, it may not be worthwhile to take it to a repair shop -- if you can find a good electronics tech with soldering equipment and a multimeter, have them check out D951 a 12 volt zener diode near the power relay. If good, then I would check out D941 and D942 in the power supply. If all three diodes are bad, the set probably took a power surge or lightening strike and could have other shorted components as well.
