Questions & Answers
Red power light flashed 5 times
There is no color wheel. This is an SXRD TV. If you have 389 at the ballast, then your ballast is bad. 5 flashes is a bad lamp driver. No TTL signal return to the mainboard. Put a new ballast in. Do not try and measure ballast output without good high voltage gear. The startup pulse is close to 20,000 volts.

Power led flashes red 3 times
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

KDS55A2020 - Replaced Bulb., now blinks red three times
Read all the recalls and the class action lawsuit over this issue in these sets that was settled and ended last year.
The safety switch is there only to prevent the lamp from being able to turn on if door is open or removed, thats it.
You have really solved or answered your own question. 3 blinks is the door is not closed or is warped from all the heat, the safety switch in your case seems MIA, going to have to find it first, it is usually a blue lever type and I suspect the plastic tab is likely missing from the door.
I would order the door and find the safety switch, it did not just walk away.
You might also be interested to know a lot of these got so hot they fused the door to the cabinet or melted the enclosure around the lamp, had two where in order to get door off had to use a Dremel cutting tool, Sony paid for all this even though set was out of warranty.
Find the switch and if snapped off or melted it and the door will both have to be replaced.
The only reason to bypass the switch is a simple one, TO KNOW IF THE SET OPERATES WITH IT DONE---no long term use, just to know the issue will be fixed.

Picture is green
The most common issue with this set is the Optical light Engine
Is it bright and consistent over the entire screen or not?
The best way is to go to a unused video input and look.
