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.

I have a problem with a: Logik 32" LED TV - Model LE32HE12 The problem is this, When you first plug the set in the power led glows red & when you go to turn it on the led switches to blue for a few seconds...


It is not with the problem to any capacitors. It is the problem with its main board itself. There should be shorted component/s at it. The short circuit protection function activates, and that why you're seeing a flash on the screen. Contact any service technician to troubleshoot. This is not a user repairable fault.

No Picture & No sound. Red LED, Green LED, Red LED.


If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

Sound but no picture


Most likely - the CCFL backlight is not getting the power it needs to come on. You can verify by shining a light on the front surface of the set - if you can just make out a dim image, then that is it. On some sets, the CCFL can be seen through the vents on the rear.
