Re: Samsung SynchMaster 214T, Princeton LCD19D and VL1919

My apologies for not responding. I have been unable to return to this monitor repair thread and hope shortly to set time aside to provide a description of the failure mode and answer other questions. Thanks for your patience.

Re: Samsung SynchMaster 214T, Princeton LCD19D and VL1919



It had not occurred to me to check that. I am forever forgetting the obvious and that was a terrific reminder and gave me hope for about ten minutes. The power supply is putting out 12.3V. Still it COULD have been the problem!

Re: Samsung SynchMaster 214T, Princeton LCD19D and VL1919

After Action Report:

I recapped as I previously suggested I would and two out of three work fine. The Princeton LCD19D, as represented by the previously posted image CIMG9761, did not work. I will order the remaining caps and hopefully get that one working as well.

I respect your recommendation PlainBill to replace all the caps. Although I had no reason whatsoever to doubt the wisdom of replacing all the caps I still like to pinch pennies and I don't mind investing some extra time in my two stage...

Re: Samsung SynchMaster 214T, Princeton LCD19D and VL1919



Very helpful. Thank you.

Re: Samsung SynchMaster 214T, Princeton LCD19D and VL1919

Thank you for the quick reply PlainBill and RetiredCaps. PlainBill I do know of your position on replacing ALL the caps. I have no doubt it is the wiser choice and I may well kick myself if I opt to do less. I will report back any subsequent failures as a result so that at least I can serve as a good example of bad choices.

Sorry RetiredCaps for omitting the URLs. I should have thought of that. And I will separate models to distinct threads in future. My previous recapping project did involve very close clearances...

Samsung SynchMaster 214T, Princeton LCD19D and VL1919

Back in May/June I had some great help from PlainBill and RetiredCaps with a Gateway fpd1975w. With their excellent guidance and encouragement I successfully restored the Gateway and two Samsungs. It was done in spite of my complete lack of electronic or electrical knowledge or training. Thanks!

I have three monitors, one Samsung SynchMaster 214T and two Princetons, a LCD19D and a VL1919, on the desk to recap and I would appreciate a review of my choice of replacement caps. Except for three caps I desoldered in...

Re: Gateway fpd1975w

I am very happy to report that today I completed the recapping of the second and third of the three non-working LCD displays that I described at the beginning of this thread. All three work as new now thanks to the guidance I received here. It is somewhat astonishing that with no understanding of electronics, or electricity for that matter, it was possible for me to repair three LCD displays for $16.47. At the next recycle I will grab every "dead" LCD I can stuff in my Corolla! The long delay in completing them was due to waiting for a soldering station...

Re: Gateway fpd1975w




OK! I have ordered the parts! I went with the tall 820s. You really won my heart with the ball peen hammer suggestion! I so appreciate your assistance with all this. You and RetiredCaps really made this a good learning process. I will post the results when I fire those babies up! At least if they don't work I will have the reassurance that it was not for lack of making a good choice with the caps. I do wonder however if it is likely that something else failed and the bulged caps are a symptom of that failure rather than the cause of the...

Re: Gateway fpd1975w



Thanks RetiredCaps! I have tended to defer to PlainBill's suggestions as he is listed as Senior Member and you have made it clear that you as well yield to some other members but you input has been very helpful. I am probably driving you two nuts but I think I am just about done with my fifty questions! I have more time than money so I lean toward the cheapest approach but I want my labor to produce good results. I know well that success will encourage me to continue and restore more gear. I see "gold in them thar hills" at the Computer...

Re: Gateway fpd1975w



The clearance appears to be 26mm. Depending on how well I can seat them against the board they might just barely fit. They probably would just fit but there is the possibility that the top of the caps would be in low pressure contact with the metal housing. Is that a problem?

With regard to the higher capacitance caps such as the 1000uF I see there is a Panasonic P5544ND [url]http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P5544-ND[/url]. Would that be a better choice than the Arcotronics Caps at [url]http://stores.channeladvisor.com/nationwidesurplus/Items/Item.aspx?nocache=1&itemid=1742378&caSKU=arco25v820uf&caTitle=%2810%29%20Arcotronics%20Radial%20Capacitor%2025v%20820uf%2010x20mm%20105[/url]...

Re: Gateway fpd1975w



Thank you RetiredCaps for all your input, suggestions and encouragement. I watched that movie and I too was uncomfortable with his handling. On that topic I understand that the caps can shock and should be discharged. I have learned this [I]after[/I] much handling of the three boards I am working with. Either I have been lucky or the caps have lost their charge. I have seen a tip to use a light bulb in a socket with exposed leads to drain the charge. Do you know how long the caps can maintain a charge and do you do anything to drain the charge?...

Re: Gateway fpd1975w

I have not located a source for exact replacement and do not want to wait for an extended period for a special order. I am rethinking whether I can fit the 12mm caps in. If I have the latitude to allow the can to not sit flush to the board but instead by leaving some extra lead between the board and can bottom I could displace the can somewhat to the side of the designated space. If I ensure there is no physical contact between components should this be acceptable? The Samsung 931 looks possible but the Samsung 204 will be more of a challenge. Alternatively...

Re: Gateway fpd1975w



Yes. I meant the 820s. I will consider the 47 you suggest. Thanks!

I have heard that increasing the capacitance is OK. It is just that kind of understanding that I am short of when trying to select from among choices that diverge from original specs. Any additional insight as to the hierarchy of parameters when making such choices would be appreciated!

Ken...

Re: Gateway fpd1975w



The 680s you suggest are 12.5mm. Can you suggest a 10mm choice? I have doubts regarding the larger size as they are pretty closely positioned. I value your expertise and am reluctant to choose with my limited knowledge.

The part number for the 47uF is for the 220uF. Would P12388-ND [url]http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P12388-ND&itemSeq=86701004&uq=634110027768595054[/url] be suitable and in keeping with your choice methodology?

Do you concur with the suggestion of the...

Re: Gateway fpd1975w



Sorry - that should be 1uF 50Volt 5 mm diam - need 1

Re: Gateway fpd1975w

I have no experience at this but I assumed it should be not too difficult to obtain replacements without having to deviate from the original size and specs. There doesn't appear to be much if any extra room for these caps and my inclination would be to not diverge from the original size. I must be missing something. Are my choices so slim by limiting the choice of brands or supply house?

Although I have little to no knowledge of electronics I was inspired to try to restore these monitors after reading about bad capacitors and how easy and cheap...

Re: Gateway fpd1975w

I also have a Gateway FPD1975W as well as a Samsung 931BF and a Samsung 204 BW. I scrounged these and others from a local Computer Recycle. I have disassembled all three and each one of them has bulging caps which I intend to replace. I would prefer to follow this forum's advice - Digikey and Panasonic FM caps - but I am daunted by the myriad choices at the Digikey ordering page. I will appreciate any assistance

Here is what I need to replace all with height limit of 20mm:
