SAMTRON 45BN HORIZONATAL PROBLEM

[chhoton]

In one SAMTRON 45BN monitor the primary problem was set dead. I have replaced two transistors Q504 & Q502. Now there is rustre (light) on the screen but horizontally the screen has been shrunk by 2 inch both sides and vertically it is ok.
Horizontal output transistor Q502 is overheating when i run the monitor.

CAN ANYBODY HELP ME WITH IT ??

ITS URGENT....

THANX IN ADVANCE
