Question about LG Televison & Video
The TV won't power up. Have tried different plug ins and no luck. Had a storm recently that knocked power out. Had the TV and a few other things plugged into surge protector and the TV is only thing that won't work now. Any suggestions?
You have to contact the authorized service centre for LG, to get an original replacement.

You have experienced a plasma eruption. The fix for this may easily surpass the value of the unit - sorry to hear that.

SOURCE: screen went black/won't power on
This is a common problem
The first step is to check the fuse on the power supply board. Next, disconnect the inverter board to eliminate the possibility of it shorting down the main and or power boards. Be careful as the inverter board supplies high voltage to the cold cathode tubes (backlights) and it bites HARD. If you disconnect the inverter and the power led comes up then replace the inverter board. (The screen will appear blank because you have no backlighting). If the power indicator still fails to light you need to suspect the main board first before the powwer supply board. The main board tells the power supply board to come on. You need to check the trigger from the main board to the relays on the power supply board. Also check the power connector to the main board because you should see +12V and/or +5V on at least some of the pins. If no power on the relay triggers then replace logic board. Then replace Power supply board last. Or buy a new monitor!!

it has (2) 8 amp 250 volt ceramic fuses, slow burn, 5mm x 20mm that needs to be replaced. they cost about $1.00 - $3.00 each. Just take off the back cover (make notes of where the 4 different types of screws go!!!) and look just above where the plug goes into the tv. A set of needlenose pliers will easily remove the fuses.

If you look at the power supply board as shown in the picture: http://assets.shopjimmy.com/media/catalog/product/cache/1/image/5e06319eda06f020e43594a9c230972d/s/j/sjdps153ap1a.jpg
There is a main fuse on the top left of the board covered by black shrink tubing, SLO-BLO 4A 250V. Check it out to see if it is blown.
