Re: Sceptre x322bv-hdr
[ATTACH]124663[/ATTACH]Waiting for a reset for the back of board
However most likely will not work due to just notice a diode that may be bad
See the pics
update: added the back of board plus diode near connector in question reading without pulling from board I should have a reading in the kilo ohms
8.53 M ohms with diode set reading of .262 V i'll need to at least replace that.
either way I suspected at least 40 to 60 V for an output to the LED's
it would be nice to have the schematic...Last edited by raykia; 12-19-2015, 11:43 AM.Leave a comment:

Sceptre x322bv-hdr
Sceptre x322bv-HDR as no backlight. Tested with a light shined on screen and can see the volume bar change
I searched high and low for schematics or service manual with no luck
Found the output to the led backlight.
21.34 v is measured out from connector cnb803 to the backlight can someone confirm this the correct reading?
Measures open on plug to the led backlight.
I haven't pulled the back to inspect led circuit.
Before pulling to inspect is it worth it to try to repair the backlight or replace?... -

Re: Sharp LC-46SB54U No Power
Yeah had one before on a plasma Vizio
I'm leaning toward main board with a faulty 15v detection circuit on main board. 15 v is present for a brief moment from power board haven't tested for short on ic1604 (hdmi) yet plus I need to isolate psb and force it on to to make sure it is functioning correctlyLeave a comment:

Sharp LC-46SB54U No Power
hey all,
is there a list that shows the blinking light pattern for a Sharp LC-46SB54U??
I have the power light and opc lights the pair blinks twice then only the opc blinks once
if some one has a list of all the blinking light patterns that can shoot my way thanks. The service manuals don't list it.
thanks -
vizio VS42L Vo Control Board (T-con)
the schematics i have is not showing the part or part number for the VO Control board .
I picked this up but looks like they may of put in a board for a 37" instead. just checking if any of you may have reference or know off hand the correct board number
I have t370hwo2 or AUO 06A22-1B
just double checking to see if that is the correct board for a 42" VS42L
thanks for checking -
