My guy, Cleveland (works at county dump) called me last week to let me know he just got in a 60" TV with intact screen & did if I want it?.
"What brand is it?", I asked. "A Westinghouse" he said. "A Westinghouse?", didn't even know they were still around yet. Somehow I lug this huge monolith home, alone.
Plug it in the wall, waiting for any pops or smoke...heard a relay click, ok that's good I guess. press the power button, stndby goes to blue, then a "W" logo comes on, then promptly goes off. connect an HDMI source, try again, same thing. Flashlight tells me backlight issues. probably an inverter board me guess's Get the back of this beast, and there's huge inverter boards, 4 of them actually, a "Master" & 3 "Slaves". Didn't take long to see an issue already. a 14 wire jumper between Slave 2 & Slave 3 was eat up all to hell, one wire was even gone, a couple others gotten so hot the insulation was gone. I separate these two and proceed to check components, what drove me nuts was everything on both boards were checking ok, 24v from PS was good, all transformers rang good, transistors, caps, diodes all good. WTF??
After rooting around in my junk bins for a new 14-pin jumper, (ended up making one) It hit me like a brick, when I was removing these boards I even mentally noted how loose the mount screws were (Visions of the Samsung crappy-screws dilemma)
So I replaced the screws w/ a better "biting" type and torqued 'em down good'n tight, added my homemade jumper, went over the rest of the boards mounting screws in the set, yup, they ALL were loose as hell. Damn TV had the dreaded Samsung screw issue. on/off/ Heating/cooling cycles had loosened every damn one of them. This thing had been starving for grounds
Paltry dilemma solved, nice picture as you can see, now sitting on my fireplace mantle.
LOLZ, I don't even watch the idiot box, but do watch movies.
So look for loose ground screws on these Westinghouses too I guess
