Question about JVC TV-20F243 20 in. TV/VCR Combo
I have a compact 14" t.v. when i increase the Volume Up the picture gets distortion (disturbing from sides) and start flickering, and when i lower the volume down the picture gets good as usuall. any solution?
I believe you have a regulation problem ,when you increase the volume the audio output IC draws more current therefore the power supply has to keep up with the increase in current,the symptom might happen if you increase the brighness to the max as well,the voltage changes need to be monitored closely to diagnose what component is not doing the work.If you are familiar with tv service this is a problem that will give you a challenge but if you are not too familiar be safe and let someone else get the headache.Let us know how it goes or if you need more information.
