Not exactly sure, but I have had related issues ( I'm an electrician) it is possible the wall outlet's polarity my be switched (hot and neutral reversed) hot is the short slot on receptacle. The best way to check is get a receptacle tester at Lowe's , home depot, etc there not expensive and easy to use if it reads open ground is not a big deal and shouldn't be the cause of ur problem, many home do not have grounds but should be utilized when possible. Good luck

    Thanks, I just tried moving it from a power strip to straight in the wall and that helped, but now the bottom 3/4's of the screen have colored vertical lines. Thanks again for the reply!

SOURCE: Sony Bravia KDL 46", no picture, standby light blinks 4 times

Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

SOURCE: horizontal half black screen, sound is still there

A plasma screen uses thousands of tiny fluorescent bulbs in different colours (red blue and green) to produce a picture. Just like standard house hold fluro lamps, these tiny bulbs use starters to turn them on and off. As there are so many bulbs in the panel and therefore starters, the panel has a number of "starter controllers". These controllers can control anywhere from a quarter up to half of the screen. If a controller dies, it takes out it's segment of the screen. Unfortunately, it sounds as if this is what has happened in the case of your LG - this is also common in NEC and Fujitsu panels. Althought these controllers can be fixed, it usually takes more time and money than it's worth- unless you have it under warranty in which case the manufacturer will just replace it. Sorry top be the bearer of bad news. hope it helps

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.

Ford fussion 2010 will start no problem but once transmission gear is selected the car appears to go into gear but will not move...forward or reverse...no dash sensor lights are on


I do not know the solution. However, I experienced the same problem on a rental in Hawaii (4 cylinder 2010 Fusion) as I was attempting to pull out onto a busy highway. Also occurred several other times.
In my opinion, it is a transmission defect and a safety issue. The car had less than 8000 miles on the odometer. Return it to Ford.

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.
