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: My LG tv (had since Nov) says no signal for the tv...

Try unplugging all inputs and the power cord from the TV for 5 minutes. This will allow the main board to reset.
Next, just plug in the power plug to the TV, power up the TV, and even though there is not a source connected to the TV, check at least three inputs and see what the TV will report on the screen for each input.
Next, turn off the TV, plug in all known working devices (Cable/Antenna, DVD, Blu-Ray, Cable/Satellite box, Game, ….) with a known working cables to the TV, make sure all the devices connected to the TV are powered up and on, and now power on the TV.
Now check to see if the TV is seeing valid signal for all the inputs connected to the TV.
If your TV cannot see any signal at any of its inputs (HDMI1, HMDI2, HDMI3, AVI1, AVI2, Component1, ……), then the main board has failed and need to be replaced.
Good Luck.

Which LG TV do you have? I had an LG TV which had a very similar problem. Luckily mine was under warranty. They couldn't fix it and so got a replacement. I could have had a go at fixing it myself, but was under the warranty.

When i inplug my lg 50pk750 plasma to power sorce turn on and before show the picture it turn off.

This issue is a common, but hardly talked about from LG. Your tv is probably 1 or 2 months out of warranty, and now you're hearing a series of clicks. After weeks of fighting with LG to replace my tv, i decided to fix it myself. i'm proud to announce that my 50PK540 is now working. want proof? Take a look at the video i posted on youtube, then you will have a better understand why your tv is clicking... I'm also selling the repair kit for this power supply board on ebay now. LG power supply Board model number EAY60968801. With anyone of these PCB # EAX61392501/7, EAX61392501/10, EAX61392501/11, or EAX61392501/12 with the parts if this kit, I've also fis several 50PK750 models, Some clients have send me their broken power supply board, so I can do the repairs. Please Make sure that you've already gone through the process of troubleshooting and testing your tv's power supply board before making any purchases.. I recommend that you get a tv tech to check it out, because every tv is different. Email at if you have any question.and watch the video:

I'm getting no output to the tv and I did triple check the connections. I'm using basic RCA cables.

I had the same problem myself. To fix it,I went into the menu for my Television set and changed the setting to VCR/DVD ... then I used the remote for the LG combo and changed that setting to AVI 1 using the 'input' button under the #9. It would not show on the front of my LG combo but did show on the TV screen. The problem is that your combo and television are not communicating with one another,like speaking 2 different languages.

Lg47lh30 having audio sync issues while viewing upper channels in hd mode. Is there a firm ware upgrade?

There are firmware updates for that issue. However, some lip-sync issues not because of the TV. They are caused by the cable/satellite box and or a home theater amplified speaker setup.
I can help you find your firmware version by using only an LG remote. You will need a pen and paper before you start.
1. Turn the TV on.
2. Select the menu button to go into your TV menu.
3. Now move the highlight to the Toolbox but do NOT select it.
4. Now push the #7 on the remote seven times and wait.
A display will come up and show you your Firmware information.
5. ****Do not power off the TV. You have to use the Exit or select Cancel to correctly get out of this Service menu.
Send me the complete Firmware information (V2.1.01) from your screen and your complete model and product code from the back of your TV(47LH30-UA.AUSJLUR).
Or you can call LG service and they can perform the updated firmware if it is needed.

Input codes directv remote (rc64), lg 47LH30

2. Locate the 5-digit code for your TV (see pages 13-16).
3. Move the slide switch to TV.
4. Press and hold in the MUTE and SELECT keys at the same
time until the green light under the TV icon flashes twice
and then release both keys.
5. Using the number keys enter the 5-digit code for your
brand of TV. If performed correctly the green light
under TV will flash twice.
6. Aim the remote at your TV and press the power key
once. The DIRECTV Receiver should turn off. If it does
not turn off, repeat steps 3 and 4, trying each code for
your brand until you find the correct code.
