I have a JVC HD-61Z575 tv which I have had for approx 5 years. I have had to replace the bulb one time approx 1 year ago, The problem I have now is that there is no red color. This started approx 1 month ago where the tv would go black and then come back on - then the red started to disappear but would return when I powered the tv off and then on again - this then progressed to the red not being present at all. Does anyone know what the cause is and how do I get this fixed? I would also like a service manual if anyone has one gijoes2010@gmail.com Thanks!
