[QUOTE="edterbak, post: 1073690, member: 69192"] I had a grounding issue myself about 10 years ago. Then it was caused by the TV cable. Not the cable itself, but the signal. This caused a ?grounding loop? (in dutch een aardelus) through the TV + receiver + VCR which are all connected to each other and a very low hum was the result. (I am no expert!!) :) When I pulled the tvcable, it was gone. Plug it back in again, its there again. I went to the electronics shop. A real one, with a grumpy old and grey man, with years of hands on experience with in his store thousands of risistors condensor capasitors diodes...and thousands more of stuff I dont understand anyway... Pipe in his mouth... mumbling ...things. :) The guy manually builds is own speakers on customars orders :p a classic pro.. .... ANYWAY!!!! This guy told me I needed to put a small resistance in the TV coax cable. I had to put it in only 1 plug of the coaxcable on the core wire. I did that and it worked perfectly. TV signal didnt suffer in any way then and the hum was completely gone. But of course this was in the time no digital TV was being broadcast. So if this trick would still work I don't know. Neither do I know the technical reason behind it why this would work or what the resistance was (0.001>100kOhm?? I don't know). [edit] If you would like to know more about the resistance. It was in my parents house. It is likely the cable is still lying around there. I can ask my dad if he could have a look at the plug and take a photo of it built in... My dad is old, so I need to talk him through it. BUt if there really is a question for this, I will try. :) Just ask. @[USER=65661]2BitSculptor[/USER] Yes, I edited the post again... :p i like to edit :) :) [/QUOTE]
