If there is audio output [sound is Ok]; then the fault with be its back light inverter board. If there is no audio too, the fault should be with its main board.

Replaced the Power/LED board on my LED TV but it didn't resolve my no picture, with sound issue. Please help!


Hi Tyler
It sounds that you're something in electronics, and are able to detect the fault. But; without getting any details; I mean the picture of the TV [inside view] I can't understand what type it is, and what faults might it have. if I give you my email address, are you ready to send it via that mail as an attachment? If you're ready, please respond here by comment. This window has some limitations to communicate each other.

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.

Se47fy19. Has sound, but why no picture?


as there are 2 completely different circuits for sound and picture in a tv set it is possible that the picture board has been damaged by the power surge . it could be as simple as a blown fuse for that board or you may have to take it to a repair shop for a proper diagnosis and a quote

How do I repair a SEIKI SE47FY19 tv?


Looks to me, you don't have the skills, nor the equipment, needed to repair electronics. It would not be wise to open any TV, because the mains voltage is in there and can be legal, if touched.
If you want to see how to open a TV, please check ifixit iFixit The free repair manual iFixit and look if they already did your set.
Be aware they show you how to open it, but don't give any warranty you then still can put it together, without buying spare parts.

How do I repair my Seiki tv?


Fault with 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.
