Re: lcd19-229 stand by light on and off
Top are 3.3V, bottom is 1.25V.
The voltages should be tested left to right, in the orientation in which the labelling on them reads the right way around i.e. you don't have to crane your neck

Re: lcd19-229 stand by light on and off

Re: lcd19-229 stand by light on and off
20V, because that's the maximum range your meter can support. If you tried to read 3.3V on a 2V range, your meter would just show over-range ("OL" or single "1")Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: lcd19-229 stand by light on and off
Can you try making the measurements as you turn the set on for the last three? You may have to turn it on and off a lot of times. A close picture of the power supply showing the label would help too.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: lcd19-229 stand by light on and off
Hmm, my error on the 1.25V. That is OK, it is just normal adjustable type. doh.
Readings seem good, so there's little more to suggest.
Can you see part U7 near one of those LDOs? What is the part # on it?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hi
Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.
Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.
The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.
I have already tried replacing all of the... -

Hi
I have an 820-2610-A motherboard that has no green light.
I have noticed is when I do a SMC reset the light on the Magsafe blinks.
From My understanding, the sys onewire circuit is responsible for the green light on the magsafe
The sys onewire circuit on this model and others is more involved
I was hoping if anyone knows about this and how it works, can reply and let me know
I know this is an old model but I am sure there are people who still works on these or knows about them
I get 1.1v on the C7771 capacitor and will replace... -
Hi guys,
I have this 2011 MBP - the company I was working for, bought it at the time for a project and gave it to me after that. Later on, I gave it to my daughter which used it for normal internet browsing and office apps. At some point the, now famous, AMD GPU issue hit this laptop as well. I disabled the use of the AMD GPU following some information I found at the time (the one that, at the end, one moved AMD kext drivers to a backup location). So the laptop was using the CPU graphics and it was ok for the said daily usage. I even replaced the drive with an SSD one and it was operating...
