Review: Great Product...Thanks!! - I bought this to replace a blown fuse in my Olevia television. Storm had caused some damage to other appliances and the TV went out as well. I opened up the back of the TV, I would not recommend doing this unless you know what you are doing as you could be electrocuted...have a trained professional troubleshoot your appliances, and I found that the fuse on the power supply was blown so I ordered these and replaced it. Unfortunately, upon powering on the set, there was further damage to the circuits on the power supply causing a small spark and yes another blown fuse. In short, pardon the pun, right fuse but further damage was done by storm then just the fuse. Repaired damaged circuit and this fuse works great. I would recommend these fuses to replace blown fuses of the same type & rating.
