gerry d :
i have 4 white dots on screen what can i do
Call mitsubishi customer service.
The dmd chips in these tv's are defective and they know it.
even if your tv is out of warranty tell them about the dots and they will:
Offer to supply the chip free to a repair center and you have to pay 200 for the service call. Refuse this. Be polite yet firm and insist that they know the chips are defective and you shouldn't be responsible for any repair cost. They will put you on hold. When they come back on, they will offer the same deal as above, plus a free lamp. Refuse this as well, politely, and state again you feel as it is a defect in their product you shouldn't have to pay anything. They will put you on hold again, and when they come back they will tell you that if you sign a "waiver"(which is actually a settlement release, as they know the chips are bad), they will pay for chip and replacement labor. And they will set the appointment up for you. You may have to pay mileage or tax depending on how far away the nearest service center is.
I just did this last week. I have since received the settlement release and signed it and returned it, now I am waiting on the service company to contact me and schedule the appt. My tv is a 2008 wd65835, btw. Far far out of warranty.
Just be POLITE and firm, they will do and say EXACTLY as I am telling you. Stick to your guns and they will fix it for free.
I tried get them to send the chip directly to me but no dice. I know they have done it in the past for people, but probably only because there was no service center within hundreds of miles. I have 2 within forty miles of my house.
It will work if you follow my directions.
Fyi this took a total of about 10 minutes to accomplish.
Good luck!
