Fault in the main power supply regulator 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. Surf the site with patience. Pull up older posts.

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 55 inch Seiki tv and when I plug it in the standby light comes on for a couple seconds than goes off and that's it. Does that mean the power unit is bad or the main board?

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

My Seiki 46 inch TV has no picture and no sound. The red and blue power light indicator do come on. What should I try to replace first? The mainboard, the power board, or the keyboard indicator board.


If you have access to a voltmeter and can measure the output voltages from your PS, see if they are within specs. If so then I would say the issue is what is being fed. And the main board deals with both audio and video so I would go that route.
