Go to www.shopjimmy.com and locate the power supply board for your tv. It's not hard to do if you're not afraid to open the back of your tv.

LG 42PQ30 plasma tv wont turn on anymore, when you plug the tv in it makes a click noise and when you hit the power button the blue light comes on then changes to red after couple seconds. Note the...


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.5_15_2012_1_19_09_pm.jpg

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.

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.
