Tell your sister to RUN from this product, if you love her. I’ve had one of these TDA-03211C models for 14 months now. The DVD unit WILL fail within the first 6 months - guaranteed. Every replacement DVD player they send you for the TV will fail similarly within a few months of normal use. The DVD unit overheats and has to be insulated by user with exaust manifold gasket material to keep it from warping the internal loading and ejecting parts. Other very common problems with this model include control box burning out within first one to two years, and gasket material pulling away from inside glass and buldging into viewable screen area. Again, these are overheating issues.
Poloroid will send you replacement parts and service in the first year but all will fail prematurely just as original parts do. They will not refund money no matter how severe the problems. They will offer to send you a replacement TV in the first year in the most severe failure cases, but it will cost you nearly $200 to ship it back and they will replace it with a used refurbished one that some other poor sucker returned. It will also fail within one year and then any extended warranty you had on the original set is gone.
Stay far away from this model and brand. An unreputable company with inferior products is all they can guarantee. I hope this isn’t too late.
