    We have a proscan PS 60690 television which we have been told by a repair man requires work on the circuit board. Are we able to gain a circuit board plan or replacement at a reasonable price?

What is the make and model number of your set. I can post a link where you can get a replacement board or have your board rebuilt if its not broken beyond repairable limits.

I have a flat pannel 60 inch sharp aquos that won turn on


Usually it is a power supply problem, so check voltages, 5V circuit is usually the culprit caused by leaking capacitor, so you have to look closely at tops of the large capacitors on power supply board and if top is swollen, that is problem, very typical in all flat panel TV's, cheap fix for about $6.00 if you have solder gun.

Good luck. FREE-PPV

Dropped mixer about 400 mm from speaker to floorsound comes up to headphones output but not to main mix socket


Open unit. 1. Look for cables knocked off. 2. Using bright light look for circuit board cracks and broken solder. 3. Look for broken pots, especially the main slider. All of these problems are repairable by competent electronics tech.

I own the JVC AV-32F475 & my sound suddenly went out. My repair man says I need a new main circuit board because the one I have is cracked. Any suggestions?


I usualy fix broken boards but if the crack is around a very small circuit traces it will be almost impossible to fix it.
