Hi!
I have this laptop and first let's go through what happened
Went totally dead, no reaction
I thought it was the adapter so I bought a new one = nothing happened
Opened up the laptop and adjusted the battery cable = Started working
Worked a couple of days and then went totally dead again
Now nothing works
I have opened the laptop, removed basically all removable components. It does not start without the battery or harddrive or anything disconnected.
Testing with voltmeter I can see 5.3V basically...

Re: The proper way to discharge electricity from a flat screen before working on it.
Talking to myself here but I did according to all tutorials and voila, I have fixed my plasma tv with "red haze" problem. Thanks all for the information provided -
Re: The proper way to discharge electricity from a flat screen before working on it.
Sorry for all these posts but this is what I will do:
- Turn off plasma tv and let it set for a while
- Get a multimeter
- Get a resistor with high enough value (this is where I am stuck now, what is high enough)?
- Remove board
- Put the resistor on the capacitor backside
- Re-solder the cold solder
- Reap the reward
Is the resistor value the only key here to think about?
EDIT: Saw a video now on youtube, a too small resistor...Last edited by pixellegolas; 12-02-2019, 03:02 AM.Leave a comment:

Re: The proper way to discharge electricity from a flat screen before working on it.
Ok, just found that you can use the resistor as mentioned before and seems very easy, just like this guide with pics show

But, is it safe to take away the board in the first place? I saw on some video that the heatsink still can give you a shock so how do people in the first place remove a board to be able to get to the backside and put on the resistor?Re: The proper way to discharge electricity fromLeave a comment:

Oh, just to be clear, I found a thread about "red haze" on a LG plasma and seems it's the Y-sus or X-sus that needs some soldering on the backside, but I am afraid to tuch them right now as they areLeave a comment:

Re: The proper way to discharge electricity from a flat screen before working on it.
Sorry for resurecting this old thread but I am about to open up my plasma TV to solder some and seems hard to find good tutorials on safety first. Aren't there any good videos now 2019 that shows how to safely remove charge in a tv? Like a newbie guide?
Feels like that is way more important than alot of other things
