Question about LG 42PC3D 42 in. Plasma Television

Open Question

42pc3d no signal ps3

I have a LG Plasma, model number 42PC3D-UE. My ps3 did work previously when i plugged in the three prong yellow white red plugs, also my hdmi after I bought one. I recently brought it upstairs to play games with my roommate and now I have brought it back downstairs and NOTHING will work. Ive tried every plug in on the tv, and tried both plug options for ps3. It keeps saying no signal. Not invalid format, just no signal. Any suggestions? Ive tried going into menu-video-reset video, that didnt do a thing. Also when I try putting the hdmi in the hmdi2 slot it wont even show up for an input option. I hope my tv isnt broken -.- Any feedback would be great, thank you :)

SOURCE: LG t.v is saying no signal on the screen for the cable box and a dvd player.

if the sky box is not registered with your viewing card, it will not show. if you want to check that the monitor is working plug in a dvd to make sure its not the monitor that is at fault.

SOURCE: plasma tv has little red dots in the black

This problem (known as sparkles) can be cured by adjusting the ramp control on the Y-Sustain board. If this does not cure the dots then there is a software remedy for the control board which an LG repair centre could fix. Failing that a replacement board is required. The orbitor & whitewash are like screen savers to help to prevent a screen burn from a permanently displayed image.

SOURCE: I have a LG 42PC3D-UE that is about 4 years old.

After 13 months of ownership (just past the warranty expiration) my LG Plasma TV developed a serious problem. These include picture degradation, shutting down at random, screen lines, color degradation and others. We systematically applied solutions such as switching cable locations, using different cables, trying a variety of power supplies (basic strips to battery backup) and nothing seemed to help. We observed the TV in different modes and kept having the same problems whether we were using the Set Top Box (cable), the DVD player or the gaming system. One observation stuck out form the rest - the problem did not occur when we were watching a black and white movie. But as soon as the film ended and we switched to a color movie, the screen popped and went blank.


I started researching the issue on-line (thank you Google!) and after some trial and error with search terms eventually discovered other plasma television owners with similar problems - some have been kind enough to post pictures and videos that allow me to see the same problems as my plasma TV. Further investigation revealed that a common culprit appears to be the Y and Z Sustain Boards. These circuit boards are akin to the vertical and horizontal deflection circuits of older televisions and are at the heart of creating a picture on the screen.


Unfortunately, the Y and Z Sustain Boards (more simply called the YSUS and the ZSUS) are a serious weak point in ALL plasma televisions. Do a Google search for problems with plasma televisions or problems with these boards and your search results will light up with hits! Information about problems with these components span years of plasma manufacturing and cover a wide variety of brand names. The worst offender seems to be LG - especially since they manufacture these boards as components for many other brands and have been doing so for many years.


Doubly unfortunate is that this problem seems to be rampant in the plasma television industry yet no one seems to know about it. It does not seem to be a safety issue (no fire hazard, etc.) so the Consumer Product Safety Commission has no information on it, it is a standard component of larger items with no particular brand involved, so the Better Business Bureau has no records on it, and the issue is spread out and technical enough that the average consumer seems to be unaware that it is such a large issue. How many plasma TV owners have to have this problem before it becomes general consumer knowledge?


In other words - this is a KNOWN ISSUE with plasma televisions yet it has somehow fallen through the cracks of consumer knowledge and the plasma manufacturing industry is certainly not be\ringing to anyone's attention.


A call to LG customer support was less than helpful. The customer service representative on the other end of the line had no information on this issue (even though it is quite common). I knew more about the inner workings of my television than he did. The LG warranty does cover the "Panel" for a two year period - and these components would appear to be core to the "Panel" - but the service rep I spoke with could not provide me a definition of what is included as part of the "Panel".


To put this in perspective, my family once owned a Sony Trinitron for nearly 20 years before it was replaced and our former primary television (still in service) is a nearly decade old Sharp CRT unit. Neither of these units developed the problem this LG Plasma is having and neither ever needed to sort of repairs (both dollar and labor wise) that this plasma unit needs. So yeah - this is big deal. When I spend the kind of money necessary to purchase a product such as a television, I expect to get more than 13 months of service out of it. I intend to get this unit repaired or replaced and I do not intend to be the one paying for it!

Remote On/Off not working - Sensor Broken


Hey, maybe you should try reprogramming your universal and see if that works. Might want to try testing all the codes that work for LG and see if they'd work. If that doesn't work, find a site like <a href="http://www.remotecontrolhookup.com/lg/">www.remotecontrolhookup.com/lg/</a> and see if you can find your original and buy it and try it out. If that still doesn't work, send it back and you may need to find a local tv repair shop to look at your tv rf sensor.

Look to see what inverter board/s this model uses---likely if two--one is bad or if one it drives the left/right sides of the Panel--should not be too hard to locate by Google the model number "boards"

My LG Plasma 42PC3D turns on and off repeatedly. I turn on my FIOS set top box first and than the TV and it turns on and off repeatedly (front bottom display goes red and green, red and green repeatedly)....


Your plasma TV has a power supply 6709900019A. These power supplies failed due to defective capacitors. See the picture below and check the capacitors mark with the red lines. There are 10 capacitors that should be replaced even if they do not show signs of bulging/swelling on top.
The value of the capacitors is 3300uF/10V but you can use 25 volts as long as they fit in the space provided by design.

hi gsgoer
Just read the description of your problem and without being there with measuring tools;
The power supply estimate sounds like a fair evaluation of the problem in your model.
Good luck with the repair.
