I HAVE LG GM 200 MODEL WITH PROBLWM OF PCB (BOARD) IS SHORT.CAN I REPAIR IT?

110 volt home mains supply? 17.9 volts over is pushing it a bit if you get any voltage surges on top of that. Integrated Circuits have a relatively low tolerance.

I would change machine brands.

Walter,

Strictly from what I'm reading it sounds to me that your PCB has failed, or is failing. You will need to either;

1) Find your specific PCB (There will be a model number on the board itself) and order a replacement online, then install it on your own.

2) If you are not comfortable repairing it on your own, contact a local electronic repair shop and describe the problem as you've described it here and they will be able to further assist you.

Attached you will find an image of a common PCB layout.

Hope this helps,
Best regards.

Then you have another board that is shorted or causing an overvoltage condition that is destroying the new PCB

If you have any one of these LG Models TV below, and all of a sudden, the screen lights for only a few seconds, then goes into standby with a clicking noise. [Stuck in standby] When you try to switch it on, it tries but then just clicks and goes back to standby? In this video, I show you the components that goes bad, and the culprit that causes it all. The power supply board has already been bought from Ebay, but I'm still selling the voltage regulator that is dang near impossible to find on ebay, as well as the REPAIR KIT for this power Supply Board. Board model number EAY60968801. With any one of these PCB # EAX61392501/7, EAX61392501/10, EAX61392501/11, or EAX61392501/12 Please Make sure that you've already gone through the process of troubleshooting and testing your tv's power supply board before making any purchases.. I recommend that you get a tv tech to check it out, because every tv is different. Remember, the component, and the repair kit will only repair power supply model (EAY60968801) with the appropriate PCB numbers. You buy at your own risk

lg gm200 mic ways

i have a lg gm200 there is no audio output from the pcb. i want d solution for it.

Hi,

I understood that the TV goes on protect mode (standby) when the control pcb is connected.

Please provide details on TV model and details on control pcb. If control pcb is a control board with touch button , look for components shorting with the chassis. If you are talking about digital controller board (big main board) then one of the parts connected to board is faulty.

Available from tritronicsinc.com are the following:

6871QZH041A Zenith/LG Z-SUS Cost: $137.44
6871QYH036A Zenith/LG Y-SUS Cost: $238.38

Hope this helps,
Dan
