The Blinking red light. suggests logical errors detected b the main board. e.g TMDS/LVDS cable being faulty. Inverter not responding etc. the cable will be the likely culprit.

It is a problem in the power supply of the set and when it blinks red (fails) count the blinks to see if they are in a specific sequence (7 blinks, pause etc.)
You need to replace your bulb. Order a replacement online---it's easy to swap and the instructions are in your manual. If you purchase one from a local dealer you will pay over $150 more!!!
This is not a problem that a reset will fix. THe 5 blinks is a code that indicates a problem with the AKB circuit. There is a possibility that the picture tube is starting to fail, but that is rare. If you are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, let me know and I will provide additional details and instructions for a couple of repair options.
