I have got a Sony Wega Flat CRT TV ? KV-AR21M83. One day its pictur e gone bad. Before this it never gave problem. Its picture started to give disturbance, coloration problem, colour bleeding and also sometimes gave no ise. So, I stopped using the TV but occasionally I switched it on to see it s situation. I called a technician from Sony but he told that he does not k now that where the fault is and I?ll have to take it to service cen tre but I did not take it. One day I again switched it on but suddenly the disturbance increased. So I got frightened and turned it off. When I again switched it on the TV started to operate normally. But another problem came up. Whenever I switched on the TV and before the picture came on the scree n, the TV displayed a green colour glow and also green coloured horizontal lines on the screen appeared for about 2 seconds and then vanished. The lin es were not completely perpendicular. The lines were somewhat slanting, rai sed from the right side. The picture itself was fine but maybe with somewha t reduced colour accuracy. I felt it so. I could be wrong. Anyways, I used the TV for 1 - 2 months and then closed and covered it as I was using anoth er TV.
After few months, I needed to use this TV again. So I switched it on. But t he TV did not switch on. This was very much unexpected. Only the LED light on the TV blinks 8 times in red. I searched to see that do these blinks ind icate something. I found out that 8 blinks as in my case indicates problem with audio IC IC406. But there was no audio problem in this TV. Only pictur e had issues.
So, what exactly has gone wrong in the TV? Is it the same component which i s responsible for TV not switching on and the earlier picture problems?
I hope that nothing has happened to the picture tube as it is not replaceab le. But If the fault does exist in some component of the picture tube then is that component replaceable / repairable or not?
Please Help. I am a novice.
