Soniq E40W13C-AU TV Stuck on standby

Re: Soniq E40W13C-AU TV Stuck on standby

Hi I've checked all the other regulators including the one I replaced. All seem to be showing the correct voltages. I'm gonna try and replace the caps on the main board. See if that helps.

Re: Soniq E40W13C-AU TV Stuck on standby

The tv I picked up was stuck in standby . I replaced the same voltage regulator as described above. The type I replaced it with was ams1117 adj ht2438 got about 10 of them delivered for $3 .
Tv works perfect now no other issues at this stage. If anyone needs these regulators I have many spares.
Thanks immensely to the above contributors that made this fix easy.

Cheers

Re: Soniq E40W13C-AU TV Stuck on standby

Hey guys,

my TV has the same problem. ausvantage which one of the three voltage regulators did you end up replacing? and do you still have the spare ones?

Is your TV still working?

Cheers

Re: Soniq E40W13C-AU TV Stuck on standby

Mine is a E40W13C-AU with a similar issue. Tv turns on via remote or buttons no problem. Everything works for about 5 min then the red led turns off and it wont respond to the remote at all. Buttons on tv still work fine. Is this common? It was a "factory refurbished" jb hifi tv. Paid less than $200 for it and closest store is 1250kms away so not worth sending back

Re: Soniq E40W13C-AU TV Stuck on standby

Hi guys, just wanted to say thanks for posting all your troubleshooting and findings; I'm handy enough with a soldering iron but my diagnosis skills are limited to replacing components that look broken

Replaced all three regs based on this guide, at a cost of $2.20 (with spares) from a TV that was found on the side of the road!

Thanks again

Hi ausvantage,
I need the AMS1117 - 3.3 and AMS1117 - ADJ and willing to buy from you. Please email me on sidkumca@gmail.com

Thanks,

Re: Soniq E40W13C-AU TV Stuck on standby

Hi all, digging up a bit but having same issue as thread poster.

Soniq E40W13C won't turn on. Limited troubleshooting tooling so i want to replace this BM1117-3.3 with the AMS1117 from above...

Will advise when done if it helps or not...

Hi do you still have some spares? Just got the TV from my neighbour havent opened it yet, same problem so im guessing same fix. Thanks

Hey Jeff, any luck ?

Re: Soniq E40W13C-AU TV Stuck on standby

Many thanks to all for the great info on Soniq TVs.

I have a Soniq E32W13A-NZ just come in, stuck in standby. Following this thread, the BM1117-adj Vo=1.422 seems suspicious but not convincing.

The Vo resistor divider measures at 100Ω to gnd and 467Ω to Vo (with the BM1117-adj still in place) which would set Vo to 1.518V. No sign of heating or stress. So 1.422 suggests an error there, but is it enough to stop the TV coming out of standby?

Can anyone tell me what the output voltage of the BM1117-ADJ should be?

Re: Soniq E40W13C-AU TV Stuck on standby

any adjustable LDO regulator is 1.25v above the adjust pin. right hand pin looking from the legs is the adjust pin.

Re: Soniq E40W13C-AU TV Stuck on standby

Fascinating post, thanks dragon - made me think. It provides the solution without answering my question. Most of my diagnosis is by what things "should" be, only rarely by what things mustn't be.

On the device in question Vref=Vo-Vj is never 1.250v, so it's faulty, done. The panel led stays red no matter what, yet Vo and Vj are fluctating as if there's somebody at home and the set is trying to start.

I've just ordered some LM1117-ADJs from RS. Many thanks for your quick response!

Re: Soniq E40W13C-AU TV Stuck on standby

Yer not wrong, dragon....I replaced the B1117-Adj and the TV is fixed. So the voltages on a working 32" TV are:

Vin = 5.105v
Vo = 1.5200 (fluctuates about 0.5%)
Vref = is 0.2718v.
Iin = Current into Vin = 176mA also fluctuating.

Being mindful that the device could have been overloaded to damage it,
I initially mounted the new one on a heatsink above the board with a 1ohm resistor in series with Vin. Boy, does the LM1117-adj get hot! There's quite a lot of headroom (Vin-Vo is roughly 3.5v) so I'll reinstate the device with a permanent 12ohm resistor in series with Vin to shed some of the heat.

All good. Many thanks dragon, and other contributors to this thread!

Re: Soniq E40W13C-AU TV Stuck on standby

awesome. these are a common failure, not just on these sets, but many others.

Re: Soniq E40W13C-AU TV Stuck on standby

Hi I am Ranjit from Sydney. I wish to convey my sincere thanks to all especially BUDM for the advice regarding the volatage regulator ivBM1117Adj as my 48"Soniq was stuck into stand by. I was getting 5.1V at pin 3, 0.14 at pin 1 and 0.73V. at pin 2 which indicated that BM117 adj is damaged. I replaced it with LM117 adj which I bought from rs online and now the tv is working!!!!!!! Thanks to all again as this tv was first purchase of my daughter's first salary. All the best to all.

Re: Soniq E40W13C-AU TV Stuck on standby

Hi all, I have a Soniq 42” E42FV16A-AU with seemingly the same issue.
I am a little confused between the differences between BM1117-3.3, BM1117-ADJ, etc and whether I would be ordering the correct part, compatible part, or completely wrong parts.
None of my bits actually say 1117.
I have a GH27G and a GH23H.
How are these different? Exactly what parts do I need to order? Can I order 2 of one part or do I need two different parts?
I can see on ebay BM1117-ADJ, AMS1117 3.3V, etc.
Thanks!

You need to look at the data sheet. The GH27G is 3.3V and the GH23H is ADJ

Re: Soniq E40W13C-AU TV Stuck on standby

Ok, so I need one of each.
Does this order look right?
And I can use this:

with wicking, solder and flux to replace them?

Sorry but didn't someone post a picture of the motherboard that showed where
BM1117-ADJ and ams1117 adj chips go?
