Install ZSUS for LG 42" Plasma

[Harleysportster64]

I have a 42" LG plasma tv (DU-42PX12XC) and am awaiting the arrival of a new zsus model. Watched the repairman remove the back and diagnose the problem so I know this is the part that needs to be replaced. Unfortunately, their charges would total $538 for the part ($395) and labor, so I went on line and located a new part for under half the price. He said he felt I could replace the part my self; however, just wondering if anyone out there can provide me with some instructions of do's and don'ts as I don't want to do something careless. He mentioned needing to ensure I discharge the power before attempting to remove the part and install the new board. I'm pretty mechanically inclined; however, just want to be certain I don't over look something in the installation process. Any help would be greatly appreciated.

Thank you,

The first step would be to leave it unplugged while waiting for the Z-sus to arrive. Several manuals will help you. The first is the service manual for that particular chassis. It can be found on Scribd. Google 22076655-LG-DU-42PX12X. You will have to register to download, but it is free and I've never gotten spam that could be attributed to them.

The also have two training manuals for LG TVs, although neither is specifically for your TV. The first is 13287511-Lg-Plasma-Tv-Full-Training-Manual, the second is 7580885-LG-Plasma-TV-Full-Training-Manual. Again, Google them. They are vital, the describe how to disconnect the various connectors. Be very careful, they are fragile.

Can anyone tell me how to release the charge from my LG plasma tv? The repairman said I must release the charge prior to working on the tv or I would get zapped and cause more damage. Thank you.

Seems to me LG recommends waiting 5 minutes after turning it off before connecting or disconnecting any boards. Discharging with thumb and forefinger across the 450 volt caps is NOT recommended.
