Soniq E40S12A-AU Stuck In Standby

Re: Soniq E40S12A-AU Stuck In Standby

resistor need high watt ,1K 10 watt and up, bulb are better. as it can handle all kind of currents / watt with out any effect on the other parts in circuit

Re: Soniq E40S12A-AU Stuck In Standby

I'm struggling to grasp where the wires come from?

which wire ? the photo i added to you.. its any table lamp with filament bulb will have only 2 wire only which take AC from wall socket... this 2 wire one you connected with the wirw which you need to slide it out from the BL socket and the next of the bulb go to the socket at pin3

sockets on power boards PIn3 -------- table lamp ------- the wire go to backlight

Re: Soniq E40S12A-AU Stuck In Standby

How about a resistor or something?

Re: Soniq E40S12A-AU Stuck In Standby

if you dont have at home... dont go to buy LOL
we just want to add it to this pin 3 line to increase resistances in hope the circuit remain on so you can use the TV.

Re: Soniq E40S12A-AU Stuck In Standby

If I'm understanding you correctly, I may have something suitable; please see the attached photo & let me know if I'm on the right track?

It is basically a switch that plugs into the wall, with the two bare wires available at the other end.....

where are the bulb ??

man its just table lamp... what do you call it in yours country ??? take a look

Re: Soniq E40S12A-AU Stuck In Standby

Or do you mean connect a wire to each of a bulb's nodes?

normal bulbs used in table lamp etc which u used to plug it in wall socket AC ... dont beak it to take out the filament LOL.... just use it as it. so if it installed in table lamp example the socket of the table lamp where you pülug it in wall take the wire out and put them end to end between the mentioned pins. ( dont forget if you use any table lamp or other device with this bulbs be sure if there switch need to be ON LOL

Re: Soniq E40S12A-AU Stuck In Standby

Do you mean the filament from inside a light globe?
Like, smash the globe to rip out the filament?

Re: Soniq E40S12A-AU Stuck In Standby

LED 2 (Pin 3) being the odd one out; hopefully this helps us progress?

let us add resistances to this line to trick the circuit keep on in case need.
if you have "table lamp" with filament Lamp from the sockets take out the 2 wire of it and connect them between pin3 ( after you slide it out from sockets ) and the sockets pin3 , just try will not harm the BL or the circuit.

if you dont have then you must take out the screen.

Re: Soniq E40S12A-AU Stuck In Standby

Hello again, sorry to let the issue go a bit stale.....

With black probe on chassis ground and red probe on each pin, here are the measurements:

VCC 1 (Pin 1) = 74V Powering On & 5.2V Post Boot
LED 1 (Pin 2) = 11V Powering On & 11V Post Boot
LED 2 (Pin 3) = 11V Powering On & 0.6V Post Boot
VCC 2 (Pin 5) = 74V Powering On & 5.2V Post Boot
LED 3 (Pin 6) = 11V Powering On & 11V Post Boot
LED 4 (Pin 7) = 11V Powering On & 11V Post Boot

LED 2 (Pin 3) being the odd one out; hopefully this helps us progress?

Re: Soniq E40S12A-AU Stuck In Standby

Thanks man, I will do that & report back tomorrow sometime...!

Re: Soniq E40S12A-AU Stuck In Standby

I am now completely stuck again; any suggestions?

you are not in stuck position at all.... we know the fault at LED backlight. and the screen must took apart to reach them for replace.

but i just keep writing to you on aim if we can use the TV with out take the screen out. to avoid panel broken or another cost of leds.

so do this test put the all pins in place and the black probe of yours meter on chassis and the red on all other pins one by one to read voltage at start ( when you plug the tv in wall ) remark the meter at start will go high then low then down when screen goes black. the reason i want to know exactly which line effected to consider way to trick it.

Re: Soniq E40S12A-AU Stuck In Standby

Sorry, I meant to say Pin 3, not Pin 6; I tried 2, 3 & 7.....

[Eggbert43]

Re: Soniq E40S12A-AU Stuck In Standby

I just tried my luck with Pin 2 removed, but to no avail.

I put Pin 2 back in the plug, & tried again with Pin 6, & then Pin 7 but nothing made any difference.....

I am now completely stuck again; any suggestions?

Re: Soniq E40S12A-AU Stuck In Standby

As I came to suspect yes, but I don't see how the 75V reading means the VCC Pin 1 & LED1/2 group is at fault?

Should I try to power on the TV with Pin 2 removed?

you can try not only pin 2 but also 3 and 7, the idea on remove. because we dont see the led strips to test leds direct. so if one get shorted this move could... could help depend on which surprise we have behind the screen.

all those move pin test will never harm the set or backlight.

Re: Soniq E40S12A-AU Stuck In Standby

Thanks Diah,

VCC (Pin 1) Rose To 75V & Then Fell To 5.2V Where It Stayed.
VCC (Pin 5) Rose To 80V & Then Fell To 5.2V Where It Stayed.

Hopefully this tells you something?

so at first group VCC pin 1 and Led-1 or led-2 are fault. mean yours early measurements on pin6 not correct
att any way you have led backlight one at most LED are open.
