i have managed to ground my pc..now whenever i connect something like my monitor to the VGA port or the printer to the parallel port i can see very tiny sparks, is it normal or did i grounded the system wrong?

Re: Grounding
It is because your other devices are not grounded, so they use the cables you connect them with as grounding cables
This can be very bad and damaging depending on the type of cable and how many thousand volts are crossing it (with static electricity a visible blue flash it at 8000 volt, electronic components like processors can be damaged by just a 30v static discharge
A discharge of below 2000v I think it is wont even be felt...)
Oh, and how exactly did you ground the system to begin with?
Atleast in Sweden it is illegal to install only one grounded outlet in a room, all outlets must be grounded"The one who says it cannot be done should never interrupt the one who is doing it." -

its funny i've handled soo many processors by hand without screwing up a single one from static electricityCap Datasheet Depot: http://www.paullinebarger.net/DS/

Re: Grounding
The voltage is probably caused by the pair of 0.005uF RFI filter capacitors (tan disks in the photo) that each connect between line and case ground (yellow/green wire in photo) and the monitor's AC power socket. When the case ground isn't connected to earth ground, the caps split the 120VAC voltage to 60VAC at the ground pin.

Re: Grounding
What exactly should i do to fix the problem??
The Monitor and the system are both connected to the same earth wireComment

Re: Grounding
No current should be flowing if both devices are connected to a grounded outlet
Get the outlets checked, either those or the cable to the monitor or the monitor itself will probably have a break in the grounding cable somewhere (or the computer)
The reason you ground stuff is so that all devices have equal potential
That means if you touch the refrigerator and dish washing machine with your hands at the same time you wont get a chock! (Same issue you see with your PC and monitor)"The one who says it cannot be done should never interrupt the one who is doing it."Comment

I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.
The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While... -
Hi. Not our mainstream line of work - we work with digital mostly. Will study the schematic found on the internet. The output darlington transistors appear to be ok. Even with no input, the output is extremely loud with static / crackle / pop. Any ideas? Will post more details and fix as we continue the review. Have not checked the main power supply rails yet (+-40V and +-16V).

I'm not sure if this is correct, the output pin 7 is grounded or the ic has a short. I'm just trying to rule it out. https://www.ti.com/product/LM2574?qgpn=lm2574

Hi,
I am repairing a DeWalt DC011 radio. I found that the secondary coil of the transformer had gone open circuit and the amplifier ic had shorted. I have replaced both but I can’t tune it in to a station and the static is very quiet. Any help is greatly appreciated. Thank you

Got a LG with color static frozen. Doesn't move just stays on this picture. I'd assume it's main board but I'm sure one of you has seen this before. Any data helps thanks...
