Several general questions: Do LED hdtv's have fewer bad cap problems in their power supplies and thus greater reliability? Can any hdtv last longer if fans are installed to provide more power supply cooling? If hdtv power supplies are cooled with fans, can bad caps be replaced with 85 degree caps?

Re: LED hdtv reliability and cooling fans
85C caps are all general purpose. You should NOT use those in a power supply. They may work for a while (if you're lucky, as not all design will work with them), but they will likely go bad a lot quicker both due to lower temperature rating and being overstressed from ripple (which will tend to increase their internal temperature).

Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....04-12-2024, 06:54 AM -
Hi,
I'm wondering if anybody out there has much knowledge of Samsung Bremen motherboards.
I've got a Samsung R530 which is about 10 years old, over the last 12 months it developed a worsening problem where when asked to do much work it would shut itself down. I had a good idea this was due to overheating which was confirmed by a temperature monitor programme which showed little balls of fire next to the various internal temperature readings. I could also prevent it shutting down if I placed a huge fan running at full speed in front of its air intake!
So I went in pursuit of... -
This is another battery testing machine that needs to be modified for the cooling fans because these are noisy but not as bad as one of the other battery testing machines that I had modified recently because of it being too noisy
The battery testing machine is going to get two temperatures controlled cooling fans like one I put in the other battery testing machine I just have to remove the temperature sensor and relocate the temperature sensor to one of the heat sinks and put one on the other heat sink so the fan speed can be controlled by temperature

Here is the eBay website link where I bought them from

I have been waiting for these switching power supplies to come well they came in today so I took one apart and found that it Capcon and EIite and another brand that is on my list of capacitors to replace on site it has several 0.47uf @ 50 volts ESR value twice the reading of a new one 10 UF @ 50 volts almost twice the ESR value of a new one 47 UF @ 59 volts with double the ESR value 100 UF almost the same as a new one it got replaced for good measure Iit was a brand if I see them... -
Good Afternoon, Good People.
I know this will be an elementary little project for most if not all of you, but I thought I would write a post and get put on track, rather than bumbling my way through it with all kinds of trials and errors.
I REALLY would appreciate y'alls help.
This is the problem - My wife and I purchased a big ol Victorian/Colonial House in NYC two years ago. The kitchen is surrounded on 3 sides by exterior walls, there is also a 1/4 of the kitchen floor (ceramic tiles) that has a crawl space underneath, and the kitchen gets FREEZING cold...
