I had this problem and paid a repairman to fix it. He said he has seen it often in this model, and immediately repaired it. It works now. He replaced two 18 pin switching modules, about a 1/4" x 2" x 1"; and 3 "micro-caps"(fuses?). It took about 45 minutes and cost over $400.

My Toshiba 53HX71 takes about 20 minutes to "warm"

This is a symptom of poor solder connections inside the set. The set will continue to deteriorate until it won't turn on at all. This is essentially a labor only repair and should not be to expensive for any TV service shop. Once this has been repaired, the set should work for many years to come.

These poor connections are caused by the continual heat/cool cycles because of use and is normal.

Most of the time the Hyper Board failing is the cause of this problem. It will eventually get worse where it also affects the HD ins. Unfortunately the Hyper Boards are no longer available from Toshiba and have not been available for quite some time. My suggestion is to coast with it and replace the Set when the HD ins fail.

You do not remove the screen on that TV. Doing so will mess up your convergence.
Chassis must be removed by a professional.

Call the manufacturer to find you nearest authorized service center.
