You must use a usb memory stick to copy data values from the old board to the new board. First you have to put the old board back in, insert the stick then follow prompts to copy register values to the memory stick. Then put the new one back in and load the values back onto the new. I would definitely have a certified tech do this process. You don't want to make a mistake with the old board values.

Plasma Television won't turn on


Hello,

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.

if otherwise the power supply board is faulty you can try websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Hope this helps

How do I get LG Plasma TV 42PQ30 to work with a dell laptop in connection use of a VGA/SVGA video cable. Thw hook up should act as a plug and play if my understanding is correct. I am using the RGB IN(PC)...


well, if the cable and adapters are friendly (meaning, you are able to plug the right video connection from LT to TV), sometimes you need to tell you LT that you have a second screen to output video. To do that, there should be a display icon in your bottom-right taskbar. Double click, and you should be able to see the options to either clone, pan, or primary your second display screen. :D

Lg plasm flat panel tv 42pq30 one month old has vertical pink and green lines that roll from bottom to top any answers.


Your set should be under warranty. This could be a clocking circuit that is out of sync, or some other processing device that is out of frame sync. To service this at board level, if it is not a standard factory known fault to correct, or if it involves extensive SMD work, the board with the fault will be replaced.

Lg 42'' plasma 720p no picture


This is not good. Was your tv unplugged or just power button off when you left for vacation. PlasmaTvs are highly susceptible to damage from power surges caused by lighting. Leave unplugged for at least five minutes then plug back in and see if this helps.
