I've got an interesting one. The audio crackles and pops when using the HDMI inputs only. if you use any other input on the TV it works just fine. I"ve found that when the HDMI setting on the input is set to 480i or 480p the HDMI audio works fine. As soon as you switch it to 720p 0r 1080I the audio strats to act up. it will quiet down and sometimes go away. However as soon as you select the menu button on the remote the crackling and popping comes back and is steady. I'm assuming that the audio amp is fine and it is related to the HDMI circuit. Not sure where to go from here.

Re: LG 50PG20 crackling Audio when using hdmi input
1) Did this just start happening recently or has this been a longstanding problem?
2) You might have a firmware HDMI handshaking/incompatibility problem. If you can upgrade both the TV and audio amp to the latest firmware, it might solve your problem?

Re: LG 50PG20 crackling Audio when using hdmi input
ah shitty!!! your probably right. I replaced the board because the ps on was not switching. I'm not sure this board had the correct level of software on it. More reasearch on how to upgrade the software I guess. Thanks!Comment

The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.
The player processes the audio signal using two different reference frequencies. The "R"... -
Hi all,
Not my usual equipment repair, Projector works great but no HDMI input.
motherboard: H550MA_R1
HDMI socket was a bit chipped on the side, but no critical damage, i replaced it anyways but still no signal.
Im assuming other damage in the mainboard.
Can anyone give me some pointers on where to begin?...06-13-2025, 09:06 AM -
Hi
The display is working great except for the HDMI. VGA, DisplayPort is fine.
i have tried several cables and sources with no luck.
Board number is 715G8912- but i didn't find its schematic anywhere.
The main chip is RTD2526FR which i didn't find its datasheet as well.
Main board looks fine without any blown components or soldering issues.
When an HDMI source is connected the screen goes blank for a few seconds and then it says, "HDMI is inactive" and enters to sleep mode.

Hi everyone,
This TV had the well known power supply issue, took ages to turn on etc until one day it never turned on, I removed and tested all output caps on the PSU with an ESR meter and replaced the ones I've marked in blue on the photo (they are the new ones).
After this it turns on fine but no signal is displayed when selecting VGA or HDMI 1 & 2 but the laptop always correctly sees the tv and brings up the name and resolution...
My new flatmate assured me the hdmi's had previously worked after waiting a long time for the TV to turn on but he... -
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
