Your problem resides in the power supply board. There are two capacitors that are near the connector the runs to the main system control board. These capacitors are leaky and need to be replaced. If you know how to solder and unsolder then componets on a board then at the most $10.00 will fix your problem. You should be able to idenify the too because they will be puffy on their tops as if they are ready to burst. The values of the caps are 1000uf rated at 10 volts, Go to Radioshack and purchase 1000uf rated at 16 Volts as this will give longer life to the unit. Also the caps are ploarized neg an pos make sure you reinstal them the same way you took them out look at the board before installing them will give you an indication of which hole is neg and pos.

it could be 2 issues: faulty remotes or stuck buttons on tv's keyboard. Where did you get 2 remotes? cable or directtv boxes? those are universal and must be programed to work with tvs. or, do you have 2 identical LG remotes in your household? either way, if you have kids on premises and lot of drinks carried around, remotes could be contaminated with fluids inside and malfunctioned. You must become a CSI and figure it out!
Good luck and let me know the results.

Reading the online manual - You should have the laptop connected by VGA - PC input
VGA Connection you need to select the correct input on the TV
  • Select the RGB-PC input source on the TV using the INPUT button on the remote control.
you will need to set the laptop up to output to the VGA output, to do this - varies by different manufacturers - But often F4 or F5, with the FN key selects the VGA output - have a look at the F keys across the top of the machine and see if you can see a picture of a screen - then use the FN and that F key together to toggle between display it will change to <Laptop Screen Only><Laptop screen and VGA output><VGA output only> not necessarily in that order.
This is the support site for that TV

If the line travels from the top of the screen to the bottom, try disconnecting the Tcon LVDS lead. The Tcon is located in the top middle of the LCD rear. Disconnect the LVDS from the Tcon by pushing in the outer lobes. Clean the contacts on the LVDs lead and reinsert. If this doesnt cure the fault, disconnect the ribbons from the Tcon connecting the LCD and clean and reinsert. If this doesnt cure the fault you have a faulty LCD.
If the vertical line doesnt travel from top to bottom of the LCD, the LCD is faulty (LCD matrix buffer).Hope this helps :)

It seems LCD Panel problem and I'm afraid, lcd panel will be replaced to fix the problem.
LCD Panel (screen) is unrepairable part and only option is to replace it.
Let me know if you have additional question.

Thanks for using FixYa. Please check the audio with a DVD player or cable box. Also try using component cables if using a RCA component cable or vice versa. Check that all of the cables are plugged into the back of the TV & MUTE button is not pressed. Do a hard reset by unplugging the power cord for more than 4 hours and power it again, then go into the on-screen-menu and make sure the sap is off and stereo in on. Also try audio from Phone and 3.5mm jacks (if equipped). If this all didn't resolves the issue then it is an Audio IC or bad speakers/speaker connection. Please do accept the solution if the issue is resolved else revert for further assistance.

I have seen this problem way too many times on LG sets. This is caused by a faulty tuner software. LG is willing to install the firmware for free if you contact them. Call (800) 243-0000 to contact them via phone or use the form at the link below to e-mail them.

A positive rating for the advice provided will be highly appreciated. Let me know if you need more help.

Thanks for using FixYa. From what you have described it seems that you might have a backlight and/or an inverter board issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or else revert for further assistance.

England is PAL format USA is NTSC, a lot of TV's can handle BOTH... a lot cannot. If I were you I would sell what I had and get one nice and new, with a warranty when I "landed" in England...That way you will not have any headaches or surprises.. may I give you a personal thanks for doing that job... keep safe soldier.

Try this, unplug all cables from the set, switch off at the mains, wait a couple of minutes, then switch the power on, and turn on your set do not put any cables back in, you should get a snowy picture up when you turn it on as normal. if you do replace turn the set back off plug all of the cables back in and turn the set back as normal, you should have a normal picture. post back if you dont.

It's all digital now - don't forget.
You need to switch from cabel to antenna first.
Play around with menus - it has to be there. Or just do areset if there.

Some stores have 30 days return policy you should take it back, and dont try to fix it yourself, then the store has an excuse not to change it. Good luck !

37LG30 - loosened the 4 screws on the back of the TV but base mount wouldn't come off. Found that had to remove the screws even though already loose so that doesn't bind in the holes. Did this by making the loose screws bind in the wholes. Using twisers in the whole would have done the same thing. o
