JVC 65 inch AV-65WP55 tv, the color red is failing


The tube is old. You need to contact a service center. He may try to boost it from inside. If it doesn't work, then need a new tube.

JVC AV-56WP74 Colors quit working or went out of balance.


Guns or CRT are probably ok. Your TV needs a convergence IC STK392-120 replacement. Lamp are used on LCD and DLP rear projection TV's. Color wheel are for DLP's. :)

Double vision on tv with purple and green colors


Hello,

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

JVC HD-52G786 shuts off


Do you have your TV plugged directly into the wall? You cannot plug into a power strip, it needs its own direct power source. Also, I have heard that there can be electrical problems inside. I have this same model, I love it, picture and sound. I just replaced the bulb for the first time last night. It was a little premature to replace it now but I know what caused it. I bought a new bulb and it works like a gem. If you ever need to change the bulb do it yourself. It takes maybe 2 minutes. The bulb looks like the Flux Copassitor and all you do is remove the door in the back on the side. Unscrew the the 2 screws that hold the bulb in and just pull out. When you put the new one in make sure you do NOT touch the glass on the new lamp. Just slid it in and screw the 2 screws back in and make sure the door is closed and tight. My uncle had a service guy do his and he got raked for 5-$600, The bulb costs about $200. Should last about 5-6 years at a rate of 5-6 hours of TV on time. Hope this helped. If not, sorry, but at least you know how to change the bulb. Good Luck!!!
