Can I use a higher voltage rating when replacing capacitors?



I want to replace two capacitors in my LCD TV. The TV starting buzzing on dark colors, etc.


Now it started cracking and buzzing really aggressively so I opened it and found two bulging caps. I have disconnected the two internal speakers for now, which has killed the noise, but I need to replace the caps ASAP.


My question is this: When it comes to replacing caps, you can go to a higher voltage rated cap but have to stick to the same farad rating?


The bad caps are both 6.3 V, 4700 µF and i was thinking of replacing them with 16 V, 4700 µF but getting the better quality 105 °C rated one as the others ones are 85 °C rated.


Just wanted to double check before I damage my TV.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
