Facing TV Problems? Ask a TV Technician.
I'm reviewing your details and will reply shortly.
White spots on the screen are indicative of a failing DLP chip in the Mitsubishi (which is a common failure point on these sets once they get on in years). There are no pushbutton fixes for this, and to clear the spots requires replacement of the DLP chip to fix the issue (it's not a lamp issue). That said, if you're a DIY type and looking to repair this yourself- let me know. The chip is available online for around $175 and there are many videos posted that outline this repair.
Alternatively if this is not something you're comfortable with, a shop generally charges $350 parts and labor for this repair and can be located using the link below:
Let me know if you need further assistance. Also, before you go, could you please click a POSITIVE RATING (by scrolling all of the way to the top of the page, and clicking 3-5 stars), so that I am credited for working with you today?
Thanks for the reply and yes- there's a link posted just above in my answer so you can locate a shop based on your zip code. Were you able to see that?
Hello, I was just following up to see if you needed further help? The site shows that since the question is open that you are still looking for help.
I didn't send you any phone numbers. The link below is a NESDA certified TV repair shop locator- it lists ALL of the shops that are listed in your area (I have no affiliation with anything it lists):
Also, you paid the website a deposit to work with me, but I am not actually paid unless you click a positive rating. Could you do that for me please?
