SOURCE: Seiki TV has NO SIGNAL message. I changed the main board but that didn't fix it. Light goes from red to blue when I turn it on. Sometimes after about a half hour I'll get signal but sometimes it'll

Do you have cable ,satellite? Does the no signal come up on all inputs?
Reset cable or satllite box by unplugging from the wall. If HDMI is being used unplug and replug HDMI at d both ends.

SOURCE: Seiki LCD TV no activity at all when power button pressed. Would replacing the main board fix this? Can that be done by an average person without soldering?

Hi Steve,
Before changing the main board for a dead TV there are quite a few things to be checked. First of all the main cord, then the fuse on the power board and then the power board. In your case please check the fuse on the power board and replace it with the same rating. If the TV starts working, enjoy watching and if the fuse blows again, consult some TV Tech.

I replaced the main board on seiki tv but now it won't come on


Put the main board back in and see what happens. If original issue is back then the replacement board is no good. If it also does not work now, then you screwed up some wiring while you were "fixing" unit.

Hello, I have 40 inch seiki tv I have a problem that the tv power work on I hear sound but the screen is blank can't even see it. What should I do or what should I buy part to fix it?


Sounds like back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. 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 inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

1 hdmi1& 2 inputs on seiki TV don't work modelSE39UY04-1 how do I fix it


First thing to check is the menu options to see if they are enabled. IF they are then you are looking at the main board being bad: http://tvchopshop.com/tv-models/seiki/se39uy04-1/

Why is my seiki tv picture jumping on and off


Fault to the main power supply regulator section. 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. 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.
