My bet is as usual some of the BGA that are bad to resolder, especially with LG is an old habit, does the s.b. led glow two times short and then stays lit long? Why did you changed the b.l. led? what's the story of this set? is it been left sitting for long in a moist ambient? bye..

Got it from a guy that bought it new .No the standby light powers on .Hit remote it blinks 3 times and goes out as it should.Changed the leds because some of the reflectors had fallen off so replaced strips while i had it apart .Looks like i need to find another main boardComment

Have you tried warming up the processor or is your hair dryer not working?Comment

I warmed it up 3 times with my hot air but no changeComment

No good for me at this point to insist, a bad made reflow cannot resolve the case, maybe worsen, better to decide if making a reballing (of what? CPU, ram , emmc/nand, what? witch price?) or buy a main board tha could work but not last long.. mad technology of fool greed manufacturersComment

It should be hot when it is fully operational, which is why a radiator is installed...Comment

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!

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... -
Hello to the forum.
My name is Christos, I am new to the forum here and i am posting from Greece.

So i tried asking for a schematic from the company and they would not give me one. Instead they... -
