I have a Samsung LED flat screen 1080 HD that I purchased in early 2007. A white pinpoint dot appeared in the middle of the screen a few months back, and now there are three altogether. Is this screen damage irreversible and can I prevent it from getting any worse?
Hi there happy to help.
Are the "dots" stationary and visible on all inputs?
Yes they are stationary and visible on all inputs...
OK, here is what is going on.........
The DMD chip/board on your TV is failing.This is the chip with the "tiny mirrors" invented by texas instruments a few years back that is the heart of the DLP light engine.This is not good news as 9 times out of 10 it is cheaper to replace the TV than perform this repair; Especially on a TV like yours that is 5+ years old. Considering the design life of the modern flatscreen TVs is from 7-10 years, the value of a used TV drops rapidly.
Most people live with the problem until the TV becomes unwatchable and then replace.
One thing to try before replacing the TV is to call Samsung here and ask if they will do anything for you, I have had some customers have luck with this. You are out of warranty but this has become a HUGE issue for the aging fleet of DLP televisions of all brands.
Please let me know what they tell you.
Sorry for the bad news here, if you need recommendations on your next TV let me know, we have alot of experience in this area here.
Samsung has informed me that as the tv is out of warranty, any repairs will be out-of-pocket for me. A technician will be contacting me within the next 24 hrs to discuss. The customer service rep stated that the cost of a repair may potentially be much less than the cost of a new tv, but that I can discuss the details and/or cancel the repair when I speak to the service technician. No real answer, but I will hope for the best. Thanks for your input!
Your welcome. My comments on replacement weren't that a replacement would be cheaper. It was in reference to the repair being more than the current value of your TV.
The TV is worth between 4-500 dollars in working order.
Its a judgment call on your part, I just wanted you to have the facts.
Have a good week.
