Need your help. I am troubleshooting an issue with my Sony KV-J29MN1AK TV The TV works fine and the picture and sound are good. But there are horizontal, thin faint lines displayed over the entire screen. These lines are white and not very bright but a bit lighter. The are spread by a distance of my two fingers at the bottom and then gradually the distance gets reduced to almost less than my first finger at the top. I tried to vary the G2 and clockwise movement helped to make these lines a bit more lighter but then the TV takes about 1 minute to show the picture whereas sound comes out immediately.
Can you help me with the schematic and service manual ? I dont know how to find the chassis number, but this is what I could read on all the boards
There is a sticker on the CRT that says KV-29JMN1AK SCC-K67PA CHA NO 0705200
There is a rectangular board that says F2 Sony 1-670-752-12 F2601 T4.0A250V
The largest mother board has following written on it 1-666-699-21 There is a very large "A" printed on the board
The PCB on the neck of the CRT has following NE M PF2 1-656-470-15 (1-710-283-15)
