Sound is perfect, turn on and all I get is two flashes of red power light. The screen is completely black. There are no backlights and the flashlight test to screen reveals nothing. Not sure what to replace. All the boards look great, no visible damage. I did review a bunch of youtube videos but can't seem to find the exact fix. Thanks! As advised replaced the T-con board. Still have excellent sound but no picture. Any other suggestions?
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.
