You have seen me write that most consumer gear is of the 5 year design variety. Cell phones tend to be much less than that.

Get estimates but a new 49 or 50 inch of comparable specs arrived at my door for just a little over 300 which included taxes and shipping. The minimum shop fee here is 150 and the trip charge is 60 or higher. Here we're running into the issue that lower product prices mean repairs are often not economical.
