Re: sony KDL-46S4100 proper voltage
can't get a menu, flow chart says if 12 and 3.3 are good at g board then go for the a board but says if no menu seen, then it's lvds cable, tcon or panel, tried a couple different tcons, same results.Last edited by nomoresonys; 12-16-2014, 08:22 AM.Comment

Re: sony KDL-46S4100 proper voltage
I was getting the solid red, green, blue then striped loop on screen, that seems to have went away, I got different a board, with the first one I have to unplug the bl-on connector from a board to g board, then backlights come on, soon as the connector make contact the lights go off, with second a board, I can have the bl-on connected but if everything is hooked up no backlight or anything, if I disconect lvds cable from a board side, backlights come on in 8 seconds BUT if unplug lvds cable from tcon side, no backlighs or anything and whatever I do the sony logo never lights up, not sure if it is suppose to and I never get a menu.Comment

I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them
The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly

3+1 Voltage Regulator for IMVP-7/VR12 CPUs
Compliant with IMVP-7/VR12, the ISL95831 provides a complete solution for microprocessor and graphic processor
core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be
configured as 3-, 2- or 1-phase VR while the second output is 1- phase VR, providing maximum flexibility. The two VRs share the
serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two chip approach.

Hi
Acer A515-43
LA-H801P
Fail: Does not charge battery, has low voltaje on connector.
Laptop didn't want to turn on, only charge led blinked.
I found PQB5 (mosfet high battery charger) in short, voltaje in +12.6V_BATT was 19 v ...
I changed it, changed PQB6 too and now battery charger voltage is 4.4V but battery is 3 cell, 11.25v, then is very low to charging.
Laptop turns on without battery and works fine, but with battery turns on and turns off inmediately, I suspect battery bad but I don't know...
