RCA and TTE Technology have refused to provide customer support for TV's made under the RCA brand by TTE Technology. Phone numbers and internet contacts are either non-existant or disconnected. The product in question is a DLP 52" tv with an increasing number of white pixel dots. I have been advised by repairmen this is caused by an inherently defective DMD chip. Unless a new $400 chip is provided by the mfg., repair cost would be prohibitive.
