Seiki SE32fy22 no backlight

[whiz62]

Got this TV from an appliance store with five others. This one is a lot different from what I am used to board wise. Pretty cheap looking. Anyway I think the LED's have a problem so before I rip apart, just wanted to get another opinion.

Got Red led on front when plugged in and blue when power pushed and voltages come up but don't know what voltage should be going to LED's. I am getting 69.7 volts out to LED'S and panel appears good I can see the "no signal" display when I shine flashlight on screen.

Never been into the led area and it appears the tab bonds are on the bottom and it looks like the tab boards are stuck to back of TV shell with double sided tape? No screws any where. Anybody else been into one of these? Thanks

There is a separate thread about this the leds themselves would have failed unfortunately, common issue with these panels.

When you find the blown leds use the other good leds from the other panels and solder them in to make a good pannle, thats what I would do as finding replacements is very hard.

Thanks ReeceyBurger123. Do you know if the tab boards are just taped to the shell? Looks like it to me so I will gently try to separate them from the shell.

The other TV's I have left are new but have broken panels. They are two 50" toshiba's and a 60" 3d samsung. Will have to see if I can use any of them.

Thanks again.

yes the boards with tab bonds were just stuck with double sided tape so here we go.

Your welcome, use a heat gun and heat the case so that the tape loosens and you can pull the case away with out damaging the tabs.

well, I guess I screwed the pooch! Found the problem and was very careful with panel and tabs, but I guess not careful enough.

Got down to the LED's and it was loose connection on bottom strip.

Went back as careful as could be and now this is what I have? Double checked T-con connections, etc.

Re: Seiki SE32fy22 no backlight

Hmm looks like a bad panel or tab issue, maybe it got damaged when you took it out unfortunately
Have you got a remote you can try doing a factory reset, or if you have another mainboard try swapping them around to be sure.

Took front bezel off and found bottom right corner has chip in panel so it is toast.. Will be more careful in the future. Terrible it was a new TV with just a loose connection on led string. Thanks for the help.

No problem let us know how the other tvs go, thats a shame but tbh the tv wouldnt have lasted long anyway be sure to keep them led strips as they can come in very handy.

Re: Seiki SE32fy22 no backlight

Thanks. Just took out the panel and think I will use it for a light source. Have gotten one of the TV's going, a 47" Vizio smart TV so at least got one good one outta the bunch. Take Care
