merong pin cushion ajustment ang monitor na yan ah, press the FUNC. button until the right most LED lights up then adjust using up or down button, same thing for the adjacent LED. kung wa-epek, something's wrong inside, pin cushion circuit, good luck finding that or maybe even the FBT.

The flybacks alright I'm sure of it and I've already adjusted all the button and any function that you could find on the front, it just doesn't work..I have googled for it a hundred times I've even emailed the company..but there response was to get it RMA'd..
I don't so..I'd rather fix it myself than send it.hehe..

Anybody can please post the specific component that's causing the problem is appreciated..

Anyway I really think it's the pincushion circuit but I can't find it anywhere..I've already check the horizontal circuit the supply section and mostly all transistors that you can find on the board..

also the diodes but not the capacitor cause I don't have an ESR..

thanks alot and more power..

Hi if this unit has double diode DMV32B at D408 then I suspect the bottom diode to be short or leaky.
