I checked the part nos and their related desc. . Below are the folowing
1. T501 is not a transistor BUT a TRANSFORMER
2. Q502 is a Transistor - Part No. - 8-729-043-43 - Transistor 2SC5426-01
3. R606 Part No. - 1-220-926-11 FUSIBLE - 0.47, 5%, 1/2W, F
I've uploaded the following SONy Service Manual which might throw some light on it.

Thanks for your excellent post. My 27v40 went belly-up in late December, 2007. The manufacture year is 1998. Same symptoms as most everyone else here.
I bought the three replacement parts you mention from mcminone.com - total cost about $35.00 with shipping. I put the new parts in and re-flowed the solder around the transformer and some other parts near the obvious hot spots. The TV now works great again!
IF you can solder well and know how to avoid getting zapped by the 30,000V flyback, then this repair is pretty easy. The hardest part is carrying that 93lb TV around!!! My back still hurts.
