Re: ACER AL1713m no power

Ok. I am now finally getting around to ordering the U850 device which is marked on the package as "SG6841S".

I think this is manufactured by fairchild but not 100% sure. I went to this web site and fairchild no longer manufactures this product. But i am not sure what to replace it with.

If you look on ebay you can find the "SG6841SZ" device but not "SG6841S".......what i am wondering is if the "SG6841SZ" device is an equivalent replacement. I thought i could get this info from the fairchild site but i am a little confused from its site because of the "not recommended for new designs" comment on the fairchild site.

Could someone help me ?

Re: ACER AL1713m no power

if you look on page 2 of the SG6841 datasheet they are compatible.. SG6841SZ is the lead-free version of SG6841.. I have just used it to replace my faulty SG6841S..

Re: ACER AL1713m no power

thanks newbie1.

so the SG6841SZ is a valid replacement. thanks.

One question, i tried to download the pdf you mentioned in your post.....i had issues downloading it. do you have the actual pdf file?

thanks again.

Re: ACER AL1713m no power

Part SG6841SZ finally came in. I ordered it off ebay from someone in HongKong ......took a while but i am in no rush.

I removed the old part and put in the new SG6841SZ and BAM! Monitor came back to life.

So you were right.......the SG6841SZ was the bad part.

Question: Regarding the 10ohm resistor.
I think i should replace this resistor......dont you guys?
I have two resistors currently in my possesion that i bought years ago a radio shack for some reason or the other.
Type1: 10-ohm Metal Oxide resistor 1 watt 5% tolerance
Type2: 10-ohm resistor 1/2 watt 5% tolerance

Which one of these should i use....or should i not even use one of these?

Thanks again......

Re: ACER AL1713m no power

congrats on the job well done..
mine is still dead after replacing the IC..

As for the resistor, frankly i am not too sure.. maybe the experts here can advise you..

Re: ACER AL1713m no power

Newbie, what are the symptoms of your monitor?

I also had to replace the following capacitors:
C867:1000UF/16v => replaced with 1000uF/25V
C862: 1000uf/25v => replaced with 1000uF/25V
C865: 470Uf/25v => replaced with 470uF/25V
C22 and C6: 220uF/25V => replaced with 220uF/35V

also the resistor R852 may need to be replaced.

Re: ACER AL1713m no power

Well, we share the same symptom & same IC problem (initially) but mine is of different monitor. To cut the long story short, now my HP f1905 is 'dead' likely to be caused by logic card (suspected EEPROM corrupted). Its ok. I keep moving on.. Anyway, I learnt & experienced a great deal from the FANTASTIC guys here, even though the monitor was not revived..

In post #27 i posted a question about a 10ohm resistor........can someone take a look at it and let me know what they think?

thanks. hope you all had a nice thanksgiving.

R1 is supposed to be a 10 ohm, .25 watt resistor. In this application it shouldn't make any difference if it reads slightly high, but just to stop you from bugging us, use the 1/2 watt resistor.
