Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appe
Hi everyone...so I am back, unfortunately. Now with a different, most likely unrelated problem. My TV is almost 4 years old. I went to watch Jay Leno the other night because I was having trouble falling asleep. About 3 or 4 minutes into watching. The green power light seemed to fade to orange real q...

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
Success! I was able to test all the voltages tonight. I had my voltmeter set to DC 200V for anyone that is wondering (AC will not work). I lowered all the voltages to the levels you listed earlier in this thread. Picture still looks good and no blue dots. TV is happily hanging on the wall again. Pro...

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
Great...thanks! I think I'm good now. I remember seeing those labels with mini holes in the board and wondered if those were test points. I'll look for the ground test point tonight as well and give this a shot. One last, really stupid question. TV should have power, but should the tv itself be powe...

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
Okay, I will try and test the voltages tonight. I guess I am a little frightened I will short it out, which is why I want to know exactly where to place the black and red leads from the voltmeter on the board. The diagram above with the stars is a good indicator, but looking for real specific, dummy...

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
Okay, I think I understand what pots are now...it's what I thought they were. I actually did this just a few minutes ago: Waited for the tv to start showing blue dots...paused it. Adjusted the VSet just a slight counter-clockwise movement...and bam! Blue spots dissapeared! Although I don't know the ...

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
Stupid question, but what are the "pots"? I'm guessing they are the white screws that I will turn to adjust the voltage. Also, I have added another photo below and circled the area where I first tried to test the voltage..where all the wires come in to the slots labeled for vscan,etc. I st...

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
Available settings on the volt meter are: ACV (200V or 500V) DCV (2V, 20V, 200V, 500V) OHM (2M, 200K, 20K, 2K, 200) DCA (2mA, 20mA, 200mA) and a little symbol that looks like sideways triangle with a line through it horizontally and another perpendicular line coming through the tip of the triangle

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
I'm a bit of a novice so I appreciate everyone's help. I have a voltmeter, which terminals am I pointing to and how exactly do I do it? Here is a photob below. I see the white screws to adjust each, just having difficult reading voltage. Also, what settings should my voltmeter be on, AC 200V? inside...

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
I actually tryed to take the panel off a few weeks back to investigate this some more, but the back of the TV was fastened by a bunch of star shaped scews it seemed. A regular hex wrench would not do the trick. Anyone know what tool I need to use?
Thanks!
Thanks!

Re: Philips 42" Plasma TV Problems - Blue Dots Randomly Appear
I also have a Philips 42" Plasma and I am experiencing the same problem. The TV is about 20 months old...just starting happening the last 4 or 5 months or so. The TV usually has to be on for at least 30 minutes before it starts showing up. it only appears when certain colors are displayed on th...
