Hi guys; i 've got this LCD SONY KDL46S4100 that i found on the streets and i'm trying save it from going to landfill,
Sony KDL46S4100,Powers up with green led no PIC or sound has back-light
i need your expertise,
the symptoms; powers up, has steady green led ,with back-lite on ,no pic or sound,already changed A board no change,
i have all supply volts, I tested power board i have at CN 301 the 12 V, 6.5 V, and 3.3 V, CN 302 stand by 3.3v,also
T-CON White fuse FP1 (3A) to the left of the LVDS connector CN1 i have the 12v.
i tested the CN1 plug per instructions see link bellow,when i pull in and out one side and wiggle it i had OSD and raster with grey pattern for a second, per tech advice see link bellow ,he says T-con is OK,i dont know, it seems like some thing is short,hope it's not the LCD,what you guys think, and can you please advice,i hate to send this set to the land fill.
i tried my Laptop with HDMI output with a video stream and PC changes sound to tv but no sound on the tv,also tried My Roku 1 with Hdmi and no sound,i notice the optical red light is on on the board thought i did not try it, i do not have the stand and remote control cause the guys only threw out the TV and i don't know who did,
also i was able to see at some point the OSD menu for some time and i could change settings but it was not for long cause at slight tv move it went away,
