Hello.How many times does the red light flash? -
When you hit power, take a flashlight to the screen and see if there is a dim picture. You gave very little data to what happens. Lgs flash 3 times red when you turn them onComment

Blink Normal . No sound or anything, I have tried removing mainboard. But nothing happens no backlight. Then I remove the panel and I tried to test all the leds one by one. They look ok. Should I try a replacement led?Comment

You did a lot of work lol. I have had similar problems with a model like this. LEDs tested fine, I replaced them like an idiot, they still tested fine. When I turned on the TV though, If I used a flashlight I could see a picture. My issue was the main board
Take a flashlight to the TV after you hit power does it show a very dim picture? You have to get very close and move the light all aroundComment

Hello friends,
A yellow light was flashing on my monitor. It was like it was constantly cutting power. When I opened it up, I saw that the big capacitor in the high voltage line was leaking. I replaced it. When I turned it on for the first time, it had the same problem again. But then, interestingly, it got better. The yellow light was on steady. But the monitor wouldn't turn on. When I examined them with a thermal camera, I saw that the Fli5961-LF reached 50 degrees Celsius and the EM636165TS next to it reached 100 degrees Celsius and was drawing high current on the motherboard....11-13-2024, 07:00 AM -
I have a XR-77A80K here. When plug in & press power, white lindicator light flashes on & off. about 30 seconds later, indicator light flashes 8x red. Checked Sony, Power reset = unplug & plug in. Factory reset involves turning it on, then pressing remote buttons when a picture shows. Well, neither of these "resets" are for a dead set like this. Anyone know what 8 blinks indicates, from the schematic? Thanks! -
Hi
I have this HP laptop, board: DA0G3DMBCE0 rev:E
The keyboard light only work, when i connect ac power supply(without battery), until the screen come with cmos checksum error. After this point light can't switch on. The first 5-6 seconds i can switch on/off light with FN+F4. When booing on, i can't switch on.
Keyb light controller Y59116, i think working, because receive i2c commands the firsr 5 seconds
I know schematic doesn't exist for this board
Someone know similar board, that use this rgb keyboard light controller?
regards

Hello all ~
I’m working on this Samsung 60” LED and purchased a new main board a couple of days ago that did not fix the 5 blink issue. The original main board’s HDMI ports (all 4 of them) failed to work and no amount of reflow remedied that.
This 5 red light blink code on the front panel LED is followed (about 15-20 seconds afterward) by an automatic reboot, and results in 5 more red light blinks. Then the entire cycle repeats itself indefinitely.
No picture. No sound.
I tested all the voltages coming out of the power supply... -
