LG 50PC3D 50 in. Plasma Television - Page 4 - Answered Questions & Fixed issues

Hello,

If your remote stops working all of a sudden, first thing you need to check on is the remotes battery, replace the batteries and try to test it again, if it works, it means that simply solved the problem and if it does not, then it means the problem is from another source.

Try to change channels from the television by pushing the channel buttons that mostly used to be by the side of the television, to see if it changes channels, if that does, then you need to find out if the remote sensor on the television is not rusty, for that you will have to unscrew the television open and access the remote sensor.

You will have to try out another similar remote on the television to see if it works, if that works, then it means the remote is bad and need to be replaced with a new one. And if it does not work, then it means loosening the television is the next thing to do to check if the remote sensor in the television is bad.

Unplug the television, then unscrew it apart, be sure to allow television rest for some time to allow the high voltage dissipate, after that you start the work on the television, then you disassemble it to see if the pins holding the remote sensor are not rusted, once you find them rusty and broken off the board, you can either replace the remote sensor or resolder it properly back on the television.

After doing that, reverse the process to reassemble the television back and plug it, then test the remote and it will work once again.

Take care and good luck

You will need the service manual.

It does sound like a power supply issue.. IF you keep making it come on to watch your going to probably cause some more damage so I recommend not watching it until its fixed..
As far as replacing the power supply here is one at shopjimmy be sure to verify the EAY32929001 part number and make sure its the same as the part listed on your tv power supply.. but it should be the correct one..

If you are skilled at soldering you can replace the defective filter capacitors which are whats causing your problem. If you click the link and blow up the picture. The capacitors are the large black cylinder parts that are shiney on the top. Also you will notice in the picture they have 2 slits on top on each capacitor making it look like an X on top. The defective capacitors will be swollen out the top like the old jiffypop popcorn lol. The bad ones are pretty obvious. On that model you can expect to replace 5- 10 of them. Be sure to replace with the exact same uf values.. Like 2200uf @ 10volts. You need to replace with 2200uf (microfarad) the voltage if a little higher is fine and actually is good. If its too much higher though the sizes will be different so its best just to be a little higher.. Say a 16volt capacitor replaced with a 25 or a 10volt replaced with a 16 is fine..
Or use the same value voltage as the original.. BUT the uf (microfarad needs to match.. They are available here

If your soldering skills are questionable then I wouldnt recommend placing the parts yourself..
You can expect to pay 150-225.00 to have the job done by an experienced TV Tech. depending on your location

You can also check here for the board on ebay I saw them starting at 80.00 for used ones..

Considering that the capacitors are probably between 4-9.00 a piece you might consider replacing the board

Good Luck and hope I covered all the options!

http://www.shopjimmy.com/lg-eay32929001-power-supply.htm make sure you check the number on the boards they have to be the same.

Thank you,

That's why I say people, do not trust power blinks, trust service specialists with experience.

Any short in any board connected to the power supply would result in , well, short at the output of the power supply.

The monitoring logic would, in turn, read that as lack of voltages and would report is as bad power supply.

Except the problem is not in the power supply, but in the external module which has shorted!

I am about to write a short and helpful article now on troubleshooting plasma TV for problems like this; I am about to post it on my blog at www.coppelltvrepair.com .

Hope it will help you!

back up memory has a small battery ....this needs to be replaced,.

I found this manual just for you! Here it is, page 39 should have the color information you desire:

Please make sure you rate my answer 4 thumbs up, it is extremely important to me. I would be forever grateful if you could do so. If you need more help on this question please just respond to my answer here and I will get right back to you.


Thanks

U have tools like a soldering iron,desoldering pump or desoldering braids,solders?Can u do basic soldering and know basic electronic.Check the power supply board for dying capacitors,these capcitors alway bulges up on it tops or puffing up on it tops.These capacitors are leaking gases and dying.Replaced these capacitors are bulges up on it tops or puffing up on it tops.The tv,power will be stable and power on wright away.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Sound like a defective z-sustain board. When looking at the back of set with back off its on the far right. It usually has a fuse which will also open when its defective.

The power supply board have problems,it not giving the tv the right votage anymore.That why it shutting down,not sustancening power to the tv anymore.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power board for the replacement.

Look on the power supply board for bad Capacitors they will be vented ,swollen or puffed up on TOP 2200uf 10v 3300uf 10v
Encompass Parts Distribution has List of Parts /Prices for this Model 1-800-638-3328 and Free Service Manual that you can print out online, Go to their Website.

The internal "starter" if you will is not firing up. Could be a fuse?
Have you tried unplugging, trying a different outlet?
If so, have you trouble shot with the manual?
Call LG if all else fails.

If still under warranty have it returned or ask for extended

warranty.

If you need to DIY, you may need to open the unit

and check everything , just to insure you will be

ordering the right board .


You might be needing tools and equipment plus a

know how to troubleshoot electronic circuits,


Faults on power supply , checking for regulators

and oscillators.

Post so we can have it started ( DIY )

It's most likely the Y-sus board (or in rarer cases the Z-sus), but to be sure you must do a few tests on the voltages to the plasma screen - Vs (~200v) Va(~70v) V-setup(~120v) and ZBias(~100v). The exact values are written on a sticker on the panel .

Hi


Thanks for using FixYa. These kinds of issues in plasmas usually occur after 3-4years as plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. You’ll need to check the power supply board first for any swollen/bulged capacitors. As power supply board is the hardest working board in a plasma TV, it develops voltage to supply all components, high current + high voltage. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Here is a clear solution,

Since the vents where blocked you might have damaged the screen itself sure the buffer will help sort most of the issue out, Remeber this is plasma not LCD, you might need a new screen, you might not accept this but at least i got the word out, if you want to keep throwing money at guess work that is your option,

But a overheated plasma could damage that actual display

thanks

Accept button if you like, or ask another expert if you hate, All you got to do is rate.

Thanks Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

I am having the same problem with my LG 60" plasma. However, now it will not come on at all? Have you found out what the problem is?

Power supply board is dead.That the board,where the power a/c plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

REPLACE YSUS BOARD AND UPPER AND LOWER Y BUFFER BOARDS ON LEFT HAND SIDE OF PLASMA PANEL.
