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.

SOURCE: SEIKI SE50FY28 !! Tv powers on to a blue light but has no picture !!

Hello,

I would try the TV inputs. Tv/Video or the Source button on your tv remote. Select each input to see if picture comes on. If you have checked all cables and Inputs, I would check the wire from the TV to the cable box.

I have a seki tv model SE50FY28 THAT HAS NO BACK LIGHT IMAGE NO SOUND NO PICTURE.PRESS POWER BUTTON DOES LIGHT UP BLUE.BUT TV DOES NOTHING.REPLACED T CON BOARD,MAIN POWER SUPPLY BOARD,PLEASE HELP


Hello sorry to say but that is a low quality TV and the actual problem is that you need to replace the LED light strings inside the panel you most likely cannot do this yourself unless your very skilled. Call a local shop and explain that u need new LED strips on your Seiki TV and in the future do not buy TVs that are made by companies you never heard of before

Unfortunately that is about the average life of a Seiki TV it could be any of the 3 boards in the TV causing this.

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.

I have TV Seiki model SE50FY28 when we turn on the TV, it works for a minute then the screen goes black, we still have audio and the flashlight test shows a faint image, what may the problem be?


Probably the back light inverter is faulty . Before going to buy a new inverter board tey to check the power supply. Which the bellow added video to know how to check a power supply board. You have to check the 24V power sto the inverter board from the power supply. if its not there then the problem is with power board. If its ok then you have to go for a new inverter board. Also try to replace the electrolytic capacitors in the power supply board. some times bad electrolytic capacitors can lead to back light failure.

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.
