Sony XBR Questions

And theft proof!

I ordered some from Encompass Parts -- hoping they are genuine.

Out of curiosity, what is the manufacturer of the genuine chips? The photo on the Encompass website shows "Shendengen" on the chip -- is that legitimate?

Encompass (the old Tritronics) sources their stuff from Sony. They are ISO Supply-Chain certified and anti-counterfeit/gray market certified as well. Just expensive, unlike the old TriTronics. We could call and get the same sales lady each time, but not so now. Tritronics, MAT, MCM (pre-Premier/Farnell), ASTI, and Fox were all the independent dealer needed back in the late 80s/90s/00s.....enter Orion and Funai and splat! No support or accessibility.

And yes, Shendengen made the originals.

248 dollars of parts (mostly 2SC4834s, MX0841s, and one lamp ballast board for aDLP set) from Encompass so far (since 2012/3), and all are genuine, but even genuine parts will fail if the original problem isn't fixed - whatever caused the original part to fail will take out any replacement.

What genuine Sony replacement source do you suggest, or use? Hard to find any Sony parts in North America anymore, much less genuine without going with Encompass - expensive they are, but original and genuine.
