Just to start this is the first tv I have opened up. I'm looking at a Polaroid tv. Did some trouble shooting online and found out the caps are bad. There is two capXon 1000UF 10v caps that have bubbled on top. Obviously bad. Need to find a place to buy new ones, but also need to make sure I'm buying the right size and all that. Any info can help. Thanks.

Hi, my Vizio M60-C3 does not power on. No lights whatsoever. Upon opening up the TV, the power supply board has 4 bulging capacitors. Each is 1000uF 16V. I have read that one can use capacitors of the same uF and higher voltage rating, but is 1000uF 35V capacitor too high of a voltage rating? My local shop only has these higher voltage capacitors so would rather just buy the 35V variety if it is OK to use them.
Any thoughts if OK to use these higher voltage capacitors? -
First of all, I'd like to mention that I'm a novice when it comes to laptop repair, although I do have some experience with soldering.
One day, my laptop experienced a severe stutter, and after rebooting, it failed to boot into Windows. I decided to disassemble it and found that the PL900 component was blown. Later, I came across a post (https://www.badcaps.net/forum/troubl...error%E2%80%99) with the same problem, where...08-30-2024, 06:13 AM -
I'm finally recapping my Soyo K7VX6 motherboard (aka KT600 Dragon Ultra) and replacing Sacon SZ-series caps. The Sacon SZ datasheet provides a spec for tan delta, but not for ESR, while the candidate replacement caps are specified in terms of ESR.
I found this nice little description of the conversion:
Calculating capacitor ESR from Tan(delta)
https://forum.digikey.com/t/calculat...-from-tan/2633
It mentions that a general spec for tan delta has to be adjusted for the specific capacitance before plugging tan delta into the formula... -
Hi, i have this RadioShack IR thermometer Cat. No 22-170 which takes 2xAAA batteriss, I've tried with NiMH AAA rechargeables but it complains about low voltage, it flashes an "empty" battery and doesn't measure anything, even with freshly charged 2xAAA NiMH, so i have to "borrow" the batteries from my multimeter when i want to use it
I'm thinking abour replacing the 2xAAA batteries with a small LiPo battery that fits inside that space, but the voltage would be too high (4.2v)
I'm open to suggestions on whether i should use an LDO or another type of voltage... -
nichiconare what i used because i had heard the voltage doesn't matter as long as it is more than the original cap. i'm now reading that high voltage may make the cap's esr too high. is this a good cap for replacing those oem ones?1500 µF 16 V Aluminum - Polymer Capacitors Radial, Can 8mOhm 2000 Hrs @ 105°C
