When I hit the power button the set does not come on but the red indicator light blinks for a few seconds then goes out. I have looked the set over for a rest button but it does not appear to have one. What is the problem? I look forward to your speedy reply.

Blinking of power LED are fault indications. Count the number of blinks occur at one time switch on. For this number, you can get an idea about the faulty section circuit inside it. It will make troubleshooting much narrower. If you wish to get more details about the blinking codes, check this link. Pull up older posts there.
IF model number posted is correct and green power light comes on for a few seconds and then goes off: On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.
Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.
Let me know what error code is found and I will tell you what it means.
When the set powers off after pressing power try pressing the menu and input buttons on the set both in together and hold for 6 seconds to see if the power indicator will blink a two digit blink code which repeats a few times indicating a specific error. Let me know the blink code if any.
When a set is powered up, there are internal checks that are performed. The initial green light indicates that power has been applied. The flashing red light indicates that a problem was found that is preventing the set from functioning properly and it has shutdown to prevent further damaeg. If you can supply the model number, I may be able to provide additional details. Also, check to see if the flashing red light has a pattern. Quite often the pattern will indicate what problem was detected.
Having similar issue with my PT-44LCX65. Lamp blew and replaced it (last month), never figured out how to reset timer. Now red indicator light blinks once every 5 seconds and after about 4 minutes TV goes black.... Any ideas?
