Hey All:
Long story short, previous owner stated they heard a "bang" and that was it. Elektrotanya has the SM for the set.
I pulled it apart, two possible suspect caps on the power board. One is leaning and slightly domed, and the huge one when running finger across is slightly domed in dead center.
So Far:
1) Red light (standby) goes to green as if it's working, no sound, no picture, no backlights. Unit has an integrated DVD player, sometimes after power disconnect, I can insert a cd and "play" it, but other times I can't, as if it's dead. (don't care about the dvd, but found it odd that it works sometimes, and not others - manual says to check voltage going to the drive, even when it doesn't work, the correct voltage is present).
2) Can't see a picture with a flashlight.
3) Test voltages from power supply to mainboard, they are all within spec.
4) Tore apart to the TCON and inverter, no visible signs of damage to any of those components. all cables secured.
5) Once the set is on (green light), I can't get it back into "standby" mode, as if I'm "powering it off".
6) During one power on attempt, the LCD flashed completely white (CCFls also came on)and immediately went off - this was barely a second. Since then, after ~50 power cycles, I've yet to see any other life from the LCD.
Any help is appreciated! Can take additional pics if needed.
