Question about LG Televison & Video

1 Answer

Model LG 42 PX3RVA ZC Hi I have a lg plasma, bought in 2005 new. I know it's old.. But was working well until a couple of weeks ago. Picture would flicker initially when turned on, then as tv "warmed up" it would go back to normal. Now it just popped and turned off, no power at all. Even red standby light is not working. Any advice to trouble shoot?

With no stand by light, you are not getting power.Unplug TV and check fuse on power supply. You will need a meter to look for shorted components and possibly leaky/bulged capacitors that are killing your power supply. flickering could be part of the bad power supply or possibly a problem with YSustain area of your TV

SOURCE: LG plasma TV turned off, after the picture very light

I think you have a defective power board. the pop sound in coming from the board and giving you a low output voltage. do it yourself price about two hundred for parts.

SOURCE: LG 42 Plasma try's to turn on but just goes back into "stanby" ?

Check to see if you get Va and Vs voltages from the power supply. There should be some wires running to the y-sus. A couple of those wires will be labeled va and vs. Are they present? There will be a sticker stuck to the panel somewhere telling you what they should be.

SOURCE: LG 42 inch Plasma TV stopped coming on. Now

With this symptom, it is impossible to tell what the exact "Cause" of this symptom is. The LED's do not tell us what is wrong, sometimes it may indicate the "Area" in your case it is the X board. BUT thats NOT where the "Fault is" thats just the part that is affected. These days unlike the "Old" analogue days it just isn't realistically possible to fix anything but the most basic of problems with todays sophisticated units. This is quite apart from the Safety aspect, any unit that can cause a firs or have an explosion, or both, is NOT to be treated lightly, and and the repairer, of the unit is legally responsible, another thing to think about. Also, one must have tools, a Multimeter, a soldering iron, a deslodering iron, an oscilloscope, a signal tracer, tools, and most important of all, a Service Manual, without which, there is no way to even begin to understand and fix it, and more importantly Program it, AFTER it has been fixed. As these days a TV, is a PC, a Tuner, and an HDTV Monitor, and more, all in one. in the "old" days TV"s were more, rudimentary, and built to last for 20 years, and a "Parts" supply was set aside. They usually used to fail for only a few reasons, and they while still difficult, were less difficult to repair. Electrical knowledge was transferable, and they could be and would respond to, This-is-the-symptom-This-us-the-Fix, But that no longer applies, as now, it can be a Fault on I squared Bus, or "Sensor" failure, or it simple may have "Crashed" just like a PC, It could be a Diode go bad, and that will stop the whole thing. You see, in the day, the sets were Very "Fault Tolerant" because they were Analouge, and a faulty, component, or more sometimes, the set would always diplay something usually, and when they didn't it was one of anly a few things, sure there are always the horrid ones, and there are pleanty of those, but all in all it was quite easy. But with Digital Electronics, it either goes, or it doesnt, there are usualy few half measures. I mean thats the definition of logic either going or not. So it can take very little to completely paralyse a set, and generally give the only sysmptom, it can, by not working, usually No picture, or the like. So you, see the list is endless almost for any given SYMPTOM, as that is what is being seen, not the cause, as I keep going on about. Also any fault, usually involves the Power Supply, it is either the cause, the cause of the damage, or it is damaged. or ALL of them. Then after you have done the electronic repairs, you then must program the set to work, and align, and set up in general, any one of those settings missed or done wrong, back to square one. So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.

Heard loud pop now have no picture i have sound .


Hello Jay,
The pop sound you herd was a blown capacitor, Open the back cover and check the main capacitor in power supply, It need replacement. But first check if the oil of the capacitor drop on the circuit then it must first cleaned then dry the area where the oil of capacitor spread.
Thanks.

BROKEN PLASMA SCREEN


Unfortunately, you'll have to replace the whole plasma screen to fix it. It's the most expensive part of the TV.
The web link below is the cheapest place to get a new screen.
http://www.shopjimmy.com/catalogsearch/result/index/?q=lg+screen&p=2

If your TV is model 42PC3D, they don't have your screen in stock right now. If you look at the other screens that are 42", the are $350 and up. Other web site will charge more than double for the same screen.

Sorry to give you bad news.

42'' LG Plasma bought in Australia doesn't work in UK?


Find out if Australia uses a different standard of HD programming than Guernsey or not since it's not picking up any channels at all with an attenna. Does the skybox use only scart connections and that's how your small lcd is connected to it?

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.
