LG 42PQ6000 plasma TV blows fuses in the wall plug
sorry to tell you but this is a plasma TV it uses very high voltage and is very complex inside do not try to go inside of this tv even if it is unplugged you will likely need to take it to a shop with experience with plasma TVs

Samsung TV Plasma heard a pop then screen went black red blinking screen
How old is the set? Are you attempting to fix yourself? The popping/no picture issue is usually do to a faulty y buffer or y sustain board. If you are willing to open up the set, I would look for blown IC chips on the y buffer (long skinny boards on the far left) boards and for any blown components on the Ysustain (located just to the right of the y buffers) board. If you are considering taking the set to a shop I'm here to tell you it will be cheaper to replace vs. repair. I hope this helps and if you have time please sign my guestbook

What to do to fix?
Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Viewing it in "

Power light flashing
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.
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
Tv powers up but goes directly into stand by mode
An Electronic component has failed. Unless you can repair circuits, take it to a shop or friend who can. Consider cost of replacement. A few hundred will fix an old tv, a couple more and you have a whole new unit.
Rainbow static on Plasma Tv
The color static, if we are talking about the same thing, is usually a digital signal interference. Check cables, and digital converter if used.
Manual
The power start pulse do not reaches to power board.
I recently had my 50 in plasma lg tv fixed. i
You say the "i tried to use its original remote and it dont work"... do you have another that does work? ex: cable box remote. I ask because if other remotes work with the TV, it may just be your original remote... batteries dead or broken. If other remotes do not work, your repair person may not have connected the remote sensor within the TV during the repair. I hope this was helpful.
LG 42PQ30 Plasma Tv Wont turn on anymore
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.
We have changed the Y sus and the Zsus boards and
Than ur tv the 2 buffers boards are good.Nothig are wrong with the Y SUS or Z SUS boards.The tv Tuner signal board is dead,that the board,where the incomming broadcasting signal cable plug into it.Try website like Ebay.com to buy a refurbish Tuner signal board for the replacement.
I have an lg 42pq30 plasma tv the main input board
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.
I have an lg 42pq30 the main input board lost
you need the set up remote, part number 105-301-m . in start mode press tools button, rt click until your model shows up. the main board is for several size screens. HIT enter when you see your model number.
