Re: LG 55LW5600 No Video No Sound
I see. I will look when I get home. None of my pictures cought that detail.
I have been reading service and training manuals, but could not figure out how to determine if backlite diodes are fine if there is no mainboard 3.3V to supply TCON board and other controls. Unless it is this 220ohm to ground test. In that case, should I disconnect cables between main and TCON board (LVDS/power)?Comment

Re: LG 55LW5600 No Video No Sound
I will contact repair shops and send my board out. I will verify that panel LEDS are fine first and then do that. Thank you for the help and your time. CheersComment

I am facing a strange issue, I don't have any sound over my internal MacBook speakers and also the video won't start. If I change to my head speaker or via HDMI (speaker on my external Display) the sound works over the head speaker or Display and also the video starts (ex. youtube).
All happened after the battery ran out of power overall several days when I was on vacation.
I tried to remove the battery and then reconnected the battery, and then the MacBook Pro 14 2021 won't accept any power from my power socket. Then I removed one speaker, connected again the battery... -
Good morning everyone,
I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.
The firmware reported is the following:
M:1.00/11107BLP
D:?.??/????????
O:1.00/11107AL
The DSP firmware given the question marks seems corrupt.
On the BCHDM-0678 - 25140678 - QPWBCHDM0678A0 board the chip that usually seems...05-11-2025, 02:59 AM -
I have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
