Re: lg 60pb660v plasma tv

Anyone out there that can help? I think it would be a pity to throw the y sus away.

Re: lg 60pb660v plasma tv

The reason I suggested testing with one y buffer disconnected in turn was that though very faint the screen shots looked as if a mid line was through the screen with buffers out of synch - hence query on control board voltage and led sequence. For me repairing boards other than for straightforward components just isn't an option because not so equipped and whole board cheap anyway in comparison.

Thanks for the help -The problem was with the Ysus, there was several surface mounted components that had failed. Replaced the components and its working fine now. (how long for I dont know)

sorry about very very late response and please ignore the surface mounted components that I mentioned earlier -it was two mosfets (I replaced the AUK C3C16 SMK0825 with 51n25) and two resistors on the ysus - the resistors were ordinary legged resistors low value resistors the large green ones (if I can remember correctly) theres two of them close proimity to the faulty mosfets- hope that helps.

I initially replaced the two mosfets and one resistor. The other resistor was fine. but when I powered it up it gave me a grainy picture I checked the components again and the other resistor needed replacing. After the resistor replacement the picture was fine.
