Re: lg 50pg4000 loses sound remote stops working and switches off
The remote board wires go to a different section of the main board that the audio. If it goes out after warmed up, I would try freeze spray on the voltage regulators and audio chip. When the audio drops out what is the voltage to the chip? The preamp IC has a lower voltage than the audio amp. Check both while your there. Do you loose the power to the IR remote rcvr facing the front of the set? I am responding from my phone so I am unable to look at a schematic.Comment

A fast and easy test is to unplug the IR from the main board and use the buttons on the set for on/off and volume up/down. If the board is bad it can cause these problemsComment

Re: lg 50pg4000 loses sound remote stops working and switches off
Which indicates it's receiving the instructions but discarding or ignoring them - the main board is at fault. On some of these main boards, there's a SUB MICOM for processing IR, standby and LED functions. The SUB MICOM connects to the main processor by I2C interface, typically. If there's a problem with the main processor or the interface, this effect might be observed.
As for repair? Main board swap is probably the only thing that can be done.Last edited by tom66; 09-26-2013, 02:38 AM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: lg 50pg4000 loses sound remote stops working and switches off
Well as the fault is caused by it running for a long time, and hence heat likely, then a hairdryer will probably make the problem worse. If you can't do a factory reset then there is no option but a board swap.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
Yamaha PSR EW400 piano intermittently loses sound and shuts down.
Youtube people recommend verifying that the DC jack's solder connections aren't broken, and the replacement of a couple of capacitors in the vicinity of the DC jack. While these solutions might work, I'd feel a lot more secure if I had a schematic to help me check the status of the myriad components.
Schematic and suggestions are welcome. -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
Hello to the forum.
My name is Christos, I am new to the forum here and i am posting from Greece.
So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.
To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.
So i tried asking for a schematic from the company and they would not give me one. Instead they... -
