Four decades of Sony Trinitron

[freakaftr8]

Thought this was kinda cool, and I was bored as he *double hockey sticks*.

In the picture is (oldest to newest)

1970 Sony Trinitron KV-1220U
1981 Sony Trinitron KV-3000
1996 Sony Trinitron KV-9PT50
2003 Sony Trinitron KV-40XBR800

I have them all connected to my AT&T Uverse thru Channel 3.

I just got finished repairing the XBR800, as it had fried and extrememly underrated sync IC's. Needed numerous adjustments in the service menu, as I think the CRT is a bit weak. Touched up the convergence, screen, drive and cutoff controls as well as focus. Looks good now.

The KV-3000 was fixed last month. It had the usual bad connections on the D board and a bad HOT. Touched up numerous adjustments like convergence (PITA) and drives/screens, deflection (pincushion) and a few other tweaks. (believe it or not, this set is the brightest and sharpest of all the Sony's I have. Emphasis and workmanship was really placed into this set when it was built. Kind of like the pride that RCA and Zenith put into thier sets in the 50's thru the 70's).

The KV-1220U I picked up from a member on the forums a few years back, working, just needed slight adjustments and the cabinet repaired.

The KV-9PT50, works great, these little sets rarely crap out. Really bright CRT.
