Re: Samsung LED uf65fh6001
it appears that every strip is bad. only a few LEDs light up per strip. even with 30VDC input. so now the hunt for new strips begins.

Re: Samsung LED uf65fh6001
that is what my further testing has kinda led me to. now i'm trying to test the LEDs properly. only a few come on for each strip when i'm up to about 10V. not sure if i'm doing it right though. 19 LEDs per strip. I start my power supply at zero and go up. once it gets to about 10V the LEDs come on but only a few. I test each strip separately. If I go higher voltage the LEDs that did come on only get brighter but the others still don't turn on.

Samsung LED uf65fh6001
Does anyone have a schematic for the PSU on this tv? BN44-00670A
i have a partially dim led with a blown diode. I'm trying to find out what blew my diode. I'm getting, what i think is, low voltage on my led connector. 150v on D2- and 250v on the rest

Emerson LED LF551EM5 Chirping/Beeping Transformer?
I have this tv here and when i try to power it on, the standby light blinks and there is a chirping sound coming from what seems like a transformer. The blinks correspond with the chirps. I have 168V on my smoothing cap on the hot side, and when I try to power it on and the chirps begin, I have 290V. I have an ESR meter and I tested all my caps and they seem ok. I'm not super familiar with how to read ESR though. I also checked for shorts and I cannot find one.
I have only the main board connected to the PSU because I couldn't figure out how to turn on the PSU without the main...

Re: JVC EM32TS LED - No Display, yes backlight
yes, that was just because i laid the board in there just for a photo. i unhooked the cable.
and i cannot test sound because I cannot change the input on the tv because I cannot see the display.
i did notice some vertical lines where the channel numbers were...

Re: JVC EM32TS LED - No Display, yes backlight
on the photos i didn't have any of the cables connected. i had already unplugged everything before remembering to take photos lol.
i did not test sound. i can hook something up real quick to play a movie so sound comes through. let me go check

JVC EM32TS LED - No Display, yes backlight
Hi all,
I'm new to TV repair. Thanks for any and all help.
I have this LED TV that lights up, but the screen stays black. I can tell the backlight or leds come on though, but no image. I can't find a service manual for it. Any help or direction on this one?...
