Question about Initial Televison & Video
The tv worked fine for like 2 weeks with some coloured lines across the top of the screen,i guess due to the broken corner. it would display barely visible black lines on the rest of the screen and other times would display just fine.Now its not working,its turns on,the screen is backlit but there is no picture,it produces the initial sound when turning on and when switching off.when you turn it on the standby led blinks six times.the tv also turns itself off after a few minutes.please advice what is wrong.From some youtube videos,it could be either a bad t-con or main board am not sure what to do.

SOURCE: 2nd try see last sentences....lg led 32ln5310 tv, sound but no picture, no backlights, nothing visible on flashlight test, what should I replace? Main board, T-Con Board, Power Supply board or Leds
The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
