my tv has been messsed up like this for almost a year now and its to the point where theres so many dots u cant see anything ….Since this was no fault of my own i think the company should comp me A-either the part and service to get fixed or B- Provide me with another one mine is a 70 in”….and would be nice to be able to get some use out of it instead of it just sitting there and people going wow thats a nice tv and my response is always ya if it worked properly….thats defective equipment on Mitsubishis behalf and not mine….If they want to keep a happy customer they will fix this now…Ive worked in management and customer service so i know how the barging begins and how it usually always ends and shold end
Hi Jenna,
People with this white death problem on their Mitsubishi have had luck getting the DMD chip replaced when they were persistent and just kept asking to speak with someone higher up the food chain. The first contact customer service can’t do anything but keep asking to speak to a supervisor. They will usually cover the cost of the DMD chip replacement and you pay for the service technician. But, some people have been successful getting the company to cover the entire cost. Just stick to your guns. Definitely a drag to have to do this. Good luck.
