Re: Samsung 245bw No Power No LED
heh, reguardless of relevance im extreemly happy to learn, i have 3 of these monitors and i tend to help others fix their computers ect, so i assume now ill have a new side job of tryin to repair things i can find repair information on.... this showed me how easy it CAN be, the hard part is finding the problem it seems, replacing the parts is really not all that bad...

Re: Samsung 245bw No Power No LED
well still no camera... BUT
IT WORKS IT WORKS YEA YEA YEA IT WORKS!!!!
i successfully replaced all those components and the monitor is now in fully working order! WOOOTT!!! i made 2-3 more mistakes similar to above, where 2 solder points touched (casue my wedge tip was definately a lil to big) but i used the wick, sucked up what i could, looked like they were still touchin with "solder flake" stuck to the board but i just did my best to redo the connections and tested it out and WALAA!

Re: Samsung 245bw No Power No LED
CRAP - so i was workin really well, about 50% done, then i solder a piece in an notice its REAAAAAAAALLLLLY close to another soldering spot, not sure if it was touching, looked like it was, so i put the wick between and hit the spot for a sec, it cleaned up prob to the point i should have stopped, but then i thought it was still to close so i went ahead and tried to suck up ALL the solder and reapply and now theres just a section of solder on the board i cant seem to pull up that connects those 2 components that never were connected before, tryin...Leave a comment:

Re: Samsung 245bw No Power No LED
Hadnt had the time to put forth into the actual project yet but ive been doin my practice on an old CRT board, pullin components off and puttin them back on, one thing ive noticed is with a Wedge tip, i can REALLY quickly solder them back on but it tends to burn the PCB a little at the point i touch the wedge down (probably cause of how much surface area is touchin the board) -- when i use the point tip i have trouble sometimes getting to the "hot spot" with the solder and sometimes i end up taking many tries heating to actually get the...Leave a comment:

Re: Samsung 245bw No Power No LED
God Damnit! now other parts are out of stock, how hard is it for a company to keep stock of tiny parts? shesh... well im gettin discouraged with every time i want to order theres a new piece to be switched out, by the time i get that figured out or some workaround and i get rdy to order again smething else goes out of stock, and i cant just replace with something else caue i have no clue so back to asking for help and if posible can i get a full order ready for me so i can just purchace and go, with the right parts.. gettin so frustrated with digikey...Last edited by Ober; 11-06-2012, 09:34 AM.Leave a comment:

Re: Samsung 245bw No Power No LED
being a noob im gona stick with the 68ohm 1watt, but i did like the idea of the 200ohm and makes sense logically and less contacts to be made..
yea, selldoor, i cant believe i dont have that monitor back up and running either, ive been either sick, playing some GW2 or researching the 27" PLS Samsungs debating moving up from these 245bw... i love my 245's but the S27A850D and S27B970D models are lookin preeeeetty nice right about now, specially with the $200 price drop on the 970 recently.... i think ill prob end up with 3x S27A850D's...Leave a comment:

Re: Samsung 245bw No Power No LED
hehe that sounds nice but is there chance that it could not work, the concept makes sense in series but i donno how electronics work that well heh? if so then id rather go with the safest bet (and by that im hoping the 1watt is not an issue in replacement from 1/2watt? or is that about equal chance of failure as the 200ohm piece) , going nuts without this monitor, only reason i havent pushed to get this done faster is cause im debating 27" PLS Samsungs's hehe, but i donno if i could power that with 580sli (1.5g) or upgrade to 680sli (4gb extra...Leave a comment:

Re: Samsung 245bw No Power No LED
Was there a reason i should be waiting after asking what Model the board was? i was under the impression something was still being checked or is the 1 watt perfectly fine to use? if so then im actually truely rdy to order hahah (as ive gotten so busy ive slacked off for long enough - and im DYING wihtout my 2d surround)Leave a comment:

Re: Samsung 245bw No Power No LED
heh, my luck again, 0 stock :P - surprised to find 2 parts at 0 stock out of 14 so far... wouldnt have thought things went in/out of stock so often..
Yes i meant the 68 Ohm, i didnt know the wattage but ive seen 1/2 to 2 watt in dif places (like ebay says their pack has 2watt) - but on badcaps mostly ive seen 1/2watt..

Re: Samsung 245bw No Power No LED
Thank you very much for your input and time, ill go ahead and put the order in... Which type of Solder should i get tho? is there a specific % of flux core thats best to go with or a certain brand thats better than others? or in this case does it not matter if im working with crappy radio shack solder?
Thanks again..Leave a comment:

Re: Samsung 245BWProblems
Im curious how much you have been payin for them... New? Used? if used how old aprox?
I bought my first one for ~$300 a LOONG time ago, easily 5+ years ago... then i got 2 more for 150 each off craigslist that were used but in better condition than the one i already owned... (guys house i went to buy it from was insane clean, definately a OCD case heh, prob took great care) but -- in the end the first one to die was one i bought used...unfortunately i did have a torch burnin MAP gas pushin a lil hot air in that direction while heatin up...Leave a comment:

Is there by chance a 245bw owner that could chime in on this? i really dont wanna end up with a wrong part, install it not knowing, then assume it doesnt work for whatever reason..

Re: Samsung 245bw No Power No LED
Well yea, thats nice dj, you now have new power supplies but the Lamps, the Caps on the Lamp board and the board your video card plugs into are all still as old as they were before...
so your spending $57 to fix a part that could end up being perfect when the rest fails... im lookin at spendin maby 5-10, learning something new (thats one of the biggest parts to this, learning how to do it, practicing working with it, its a fun project when your getting help, Selldoor has made this a very enjoyable learning experience for me) but if...Leave a comment:
