Re: Problems with JVC AV-32WR4EK

This could denote a power supply problem. or overcurrent protection due to a component going bad. If you do not have electronics experience, "DO NOT TRY TO WROK ON THIS SET" people have been seriously hurt trying to repair TV without knowing the basics of electronics. If this is a power supply problem it may be the HV supply and the switching power supply (IVHT based) or the low voltage starter supply. In both cases I would advise you taking it to the shop for repairs.

I have a jvc tv , old, model no av-48wp34....turned it on hsd sound pic everything normal , changed channel, picture went 80% black , stil have sound

HI Bonnie,

If you have a good picture when it's on then it points to a dry joint on the circuit board, It is probably round the switching transformer section or the eht section but please be aware of the very high voltages stored in the capacitors and tube.

If you need any more help don't hesitate to contact me.

Progressive power up problem

Yeppers. Sounds like the standby power supply has a bad capacitor in it and the regulator Ic is defective. These parts should only be replaced by quilified technician as there is very high voltage inside these sets. Good Luck
