Which one is true, or anyone had experience with same this symptom? Thanks alot for solution.....[img][/img][img][/img]

Make sure you never take anything to that technician, he has no idea what he is talking about. Your friend is most likely incorrect as well. 
It looks like the width is not changing, right? It's only the height? If so, there's a problem on the V board somewhere (most likely) or hte CPU board. Start by pulling out hte CPU boards and reinserting them, do the same with all connectors on the boards right under the top cover.

THE set layout is here. The CPU boards are under the metal cover/card cage between the R and G tubes.
