Toshiba 50h12 convergence suddenly went bad. Appeared to be magnetic interference. Opened the front. Turned it back on. I notice that when I turn the green color knob so that green covers the screen, the tv shuts off. Will replacing the middle "green" tube fix this problem?
This is what you need.

The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

That is the classical sound of a Switchmode power supply, detecting an "Over current" situation and shutting down, for "Safety" reasons, like fire explosion etc. I get these in the shop frequently, (actually they seldom get to the shop, more, we go to them, as they are so BIG) This is a common occurrence. But can have many, many causes, the Power Supply shutting down, is a "Symptom", of the actual "Cause". Unfortunately, as related there are many areas that can cause this to happen. It literally can be in any section, or part of the circuit. really, the only way to effect a fix, is to first get a Service Manual. It is well worth the price it costs to get one. Simply Google the name off your TV, and add the words "service manual" after, Panasonic PT-53X54 service manual The manual gives service algorithms, to work through, to isolate the problem. It is still quite a challenge in any event. Rear projection TV's do have what seems to be a higher failure rate than the "Normal" TV's. Also they seem to be more expensive to repair. If you decide to get a repair ensure you get a firm "Quote" before proceeding. No "Quote" no job. If you choose to do it yourself.. good luck

power light if it shuts down should blink a error code--count the blinks and a pause?

After you turn on and green power light comes on and then goes out:
Press and hold both the menu and input buttons on the front of the set for at least 5 seconds and release both buttons.
Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it 4 more times.
Let me know what error code and I will tell you what it means. If this information told you something you did not know, rate this solution as very helpful as I do this here for free.
