So I was given one of these Dynex DX-22LD150A11 TVs that has been posted about in a few other threads here. I reviewed the five threads I believe I have checked all items that were mentioned in those threads. Results are below.
Issue: No Life (No Video/possibly no audio) -- but kinda shows power. I assume no audio, haven't been able to blindly switch to a connected HDMI source.
Symptoms:
It does do:
Measurements:
Off
Power Board to Control Board lines (PSU side)
DIM = -.055v
BL_ON = 0.0
12v Lines = 13.44v
5v Line = 4.86v
AC_OFF_DET = .199

P1 -> P3 = 0v
P1 -> P4 = 164v
P1 -> P5 = 3.81v
P1 -> P6 = 0v
P1 -> P7 = 13.23v
P1 -> P8 = .054v

P1 -> P7 = 0 ohms
I don't see anything visibly on the board that looks suspect. Any thoughts?
Pictures attached of the Power Board and Control Board. Two of each side (front and back). One with and one without camera flash. I did find this little guy in the last picture.
Thanks!
Issue: No Life (No Video/possibly no audio) -- but kinda shows power. I assume no audio, haven't been able to blindly switch to a connected HDMI source.
Symptoms:
- No click
- No back light (not even a flash -- confirmed in a pitch black room)
- No response from buttons
- Nothing from the DVD player
- No other life what so ever, even when pushing buttons
It does do:
- Red light is ON with power cable plugged in.
- Red light changes to blue when power button is pressed.
