Hey there all Hope everyones well, Ok I know this tv has been gone over in the threads a couiple of times and trust me I have read them over and over and am still having issues with this tv . It does the norm clicks when you turn it on, cycles through shuts off then clicks back on, I get NO pictures (sound: havent hooked any source to it yet) I have tried the unplugging of the Y main, does same thing. I have tried the X-main off ,still nothing. Both unplugged, nothing.
I have tried the PSon and the VSon jumped with a resistor, pins 3 & 4 jumped on logic board and lvds cable off, and still nothing. If I unplug power to main/video board with said adjustments made, TV doesnt even come on. I ested the Y-buffer boards didnt seem to show a short there .
ok I have tested the V's on the plugs and will list them . Can someone please help me to see what I am doing wrong here . I am just a hobbyist here and couldnt pass up a free 58" tv. Thank you in advance. Hopefully we can figure this thing out.
Voltages on the plugs
PwB to Y-Main are as follows Panel states (VS 202v) (VA 55v) (VSC -190) (Ve 95 )
VS--- Peaks at 200v then settles at 193v
VS--- Peaks at 200v then also settles at 193v
GND--0v
GND--0V
VCC-- 14.96v (supposed to be 15v)
GND--0v
GND--0v
VA--- Peaks at 56v settles at 53v
VA--- Peaks at 56v settles at 53v
Pwb To X-Main
VS--- 193v (peaks at 202 before drop)
VS--- 193v (peaks at 202 before drop)
GND--0v
GND--0v
Vcc---14.96v
Pwb to Main Board
AcDet-- 4.4v
15v---- 14.94v
GND--- 0v
D5.3--- 5.15v
D5.3--- 5.15v
GND---0v
GND---0v
Vamp--18.02v
GND--- 0v
stby--- 5.15v
VSon-- 3.21v
PSon---3.26v
Pwb to Logic board
VSon---3.216v
PSon---3.26v
GND---0v
GND---0v
The Va test point is 193v
The VS test point is 53v
Hope this Helps or if you need other readings let me know, Thank you in advance for looking into this with me.
The pictures are the exact same tv and were borrowed from MyEvolution . Thank you for those.
