I've been reading this topic for a few weeks, along with other websites, and here's my story.
I've got a LG 42PC1DA 42" Plasma, which i purchased November 2006.
Aprox 4 weeks ago (25/03/2007) i noticed the slight scatter of RED Dots, like a now effect of red pixels.
I called LG, and they sent a local engineer to take it away, which they did.
10 days later, it arrives back, and i was over the moon........ UNTIL i switched it on.
It hadn't changed, the dots were still there, AND the rear panel was scratched with a screwdriver!!!!! I was FUMING!!!!!
These are the parts they Supposidly changed, i will copy the text as it is:
1 x 6871QCH077C
1 x 6871QYH053B
1 x 6871QZH056B
Replaced Y-SUS, Z-SUS, CTRL PCB all within Spec, This is a HD ready PDP will only work correctly on HDMI.
I called the Techinican company that had taken the TV within the first 60 seconds of having it switched on, and to my surprise, the technicians Actually tried to Fob me off with some crappy story.
"The reason you see the red dots, is because you have too many tv channels on the tv" - yes, that's what he actually said to me. I went on to ask, WHY does it do it with the Playstation, Xbox, DVD player and my Digi Camera?
His reply was, get this - "As i've said, it's down to you having too many TV channels on your TV" - At this point i laughed out loud, in utter disgust at this Cowby!
So, i asked WHY did you change all the above parts, if it made no difference what so ever to the TV?
The final reply i got was "It's a common fault with LG tv's, and we can't fix it"
OK, i said, i will report you to LG to ensure that you are not paid your fee for fixing my TV, as you haven't fixed it............... The technician is coming to my home Tomorrow (18/04/07) to have another look at it!
I jumped on the phone to LG, and explained ALL to them. And they ensured me it's not a common fault and they will send ANOTHER company out to me to view it.
I then called the shop i purchased it from, and have asked them to deal with it, they are ordering ALL the parts mentioned above, and will come to my home next week.
I pray this is fixed.
So, i have my TV back, with just as many Red Dots, AND scratches to the rear.
I'll post a Video and pictures Later
