I managed to re-solder them on and they then worked perfectly.įast forward to today, about 9 years later, and my brother is still using both the repaired monitors. As I recall one or more of replacements they had available on hand had a different "number" on it, but they assured me it was a higher rating and wouldn't affect use, I don't know much about electronics, but this made sense to me so I trusted it. I went to an electronics shop expecting that someone there would be able to advise on replacements which would work. I opened up the monitor, saw two or three capacitors which were clearly bulging and I used a soldering iron to get them off the board. As I recall, I watched a YouTube video and was confident that if the problem was just the capacitors, then I could manage to replace them.

I have little to no knowledge of electronics, but did know how to use a soldering iron.

I did this kind of a repair job to a couple of Samsung 23" 1080p screens back in 2012.Ī friend gave them away since their backlights would flicker making the monitor unusable for the first 10 or so minutes after they were turned on, after which they worked completely fine. Some in fact can degrade without showing any visible hints of their condition. However, you can just ignore the 2nd sentence if repairing a device would require just a bunch of capacitors quality ones aren't that pricey, and if you find a bulged one, it is often advised to replace all capacitors employed in the same stage anyway. Therefore, the lower the ESR, the better quality or condition is the capacitor.

The ESR is an unwanted static series resistance the capacitor would exhibit no matter the frequency it works at, it increases with aging and it's independent from the capacitive reactance which it's related to the frequency.

Leakage (ie, when a capacitor exhibits resistive properties by conducting current also when fully charged) can be measured easily by using an analog tester or a digital one plus a few parts, while the ESR (equivalent series resistance) measurement would need a proper instrument called ESR meter. Some can be easily spotted by visual inspection for being bulged just like the one in the linked article photo, others will need to be measured. Low ESR rated ones are preferred if you can, buy them instead of generic ones. Capacitance is usually not critical electrolytic capacitors accuracy can be worse than 20%, and that's not a problem because they're not required to be accurate for their job, so if you don't find the exact value, you can safely swap the part with one with slightly higher capacitance same for the rated operating voltage which can be higher (not lower!). Capacitors mounted into a power supply are exposed to higher temperatures, so always choose the 105c degrees type.

sellers are relabeled fakes) pay them more but pay them once.Ī web/image search for "counterfeit capacitors" works better than 1000 words.Īnyway, when shopping for (hopefully genuine) electrolytic capacitors, respect also the temperature ratings. If you see a TV/monitor going off randomly or a LED lamp starts flashing, pretty sure there are one or more defective capacitors in there.ĭefective capacitors are a common plague in modern electronics, and the culprit is always the capacitor: the market is literally invaded by rubbish quality capacitors, and swapping a bad quality one with another bad quality one guarantees it will fail again one day, so buy only reputable parts from reputable vendors avoid online purchases of branded parts from unknown resellers (pretty sure that 99.999% of Nichicon or ELNA capacitors sold by any Aliexpress, Ebay, Amazon, etc. just by replacing bad capacitors, and in a few cases some diodes too, so it's worth trying especially on electronics that would otherwise be thrown away. If your game looks blurry or stretched and distorted, check its display settings and make sure you set it to the right resolution for your screen.I've repaired several TVs and monitors, LED lamps, etc. It’s common for video games to default to a resolution that’s different from what your monitor requires to look sharp. Some full-screen apps and video games can control and take over your system’s resolution. For example, if your display has both an HDMI and DisplayPort input, then switching to DisplayPort will give you access to higher resolutions and refresh rates in most cases.Ĭonfused? Check out DVI vs HDMI vs DisplayPort – What You Need to Know. In some cases, you can fix this by switching connectors. In short, check that both your GPU and cable support the resolution you want.

For example, you need a category 3 HDMI cable to run a 4K display at 60Hz.
