Inverter card.

The inverter card drives your cold cathode lighting.
If you pull the covers you will find all the lights out, if any of the eight legs of the inverter go out (driver transistor) the card will not work.

hi ;
your LCD TV has a fuse, but you said it has orange light.
maybe there's problem with power supply
try some basic troubleshooting
you have to remove back cover ,then check power supply section, some power supply has
built with inverter board that supply the bulb of LCD.
check for bloated capacitor ,you can do some soldering by removing capacitor. try to watch this http://www.youtube.com if you know how to solder, or even disassemble the back of LCD TV.
if this procedure wont help, maybe some parts has a failure. make some comment so i can help you more further.
thanks ,, hope this help........

HelloThis type of fault occurs to LCD TVs are aminly due to its LCD backlight failure. Check the CCFL tubes for damage. Check the backlight inverter board too. You have to open the tV to do any repair to this fault. You must have sound knoledge in electronics to do this work.OK.

Same problem here too. Happens everyday now until power is off for a while then picture is stable. Thought it was interference, but I'll look into the overheating issue a bit more closely.

Hi,
You have back lights problem and need to fix at repair shop.
Regards

You may be looking at an interference issue you can set up or get a remote that can be set up for UHF signal through DISH. Also you can just access the back lighting option for your TV in the menu's and disable it that should resolve it.

First, you need to find out which board (s) is bad first by taking some voltage measurement first. No picture can be caused by a dead 24vdc power supply, inverter board, T-CON board, main board.
Please read my guid to have some basic understanding how LCD flat panel TV works.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board. if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having. If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Please see my basic troubleshooting guide here: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide Failed TV and Monitors: http://s807.photobucket.com/home/budm/allalbums http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.
