Horizontal line during Vertical Blanking

Hi Everybody
I have got a Sanyo ce21mt4-b and it worked fine. Recently I got horizontal rasters in the Vertical Blanking interval so that the image has been faded by this lines . They are disappeared by adjusting the trimmer on the HV transformer but the TV is suddenly goes to standby and switched off which I think is done by the on board CPU overcurrent detection. The rasters are appear again by adjusting the trimmer but the first problem still remains.
I have traced the PCB and it looks that the vertical control IC LA7832 has gone. I am not sure about it, but I have checked most of the Diodes. Also I am not sure about the capacitors. Can anybody kindly help me to find the problem? Also Does anybody has the schematic diagram of that model?
Thanks in advance for your kindly reply
