It's about the capacitor marked there in the Focus circuit, which has a 25V 6.8UF rating. I replaced it a while ago with two 10UF 50V electrolytic capacitors, negative to negative. After 30 minutes of watching TV, one of them blew up, and that killed my horizontal deflection. The question is, did it break one of them?

Loading...I recently bought the Sony BDP-S6700 Blu-ray player. Since it has 4K upscaling, I thought it would play 4K Blu-rays. I bought a 4K disc, but the player doesn't recognize it at all. I have a Sony 4K TV and an HDMI 2.0 cable. What could be the reason it's not being read? Is it…
Since yesterday, there's been a thin line at the top of the screen. It sometimes disappears and then reappears. I didn't hit the TV either😅 Is there anything I can do about it?
When I watch Netflix on my phone, it sometimes skips something, then the video freezes for 10 seconds while the audio continues, and then suddenly it's a few seconds to minutes further.. just now 3 minutes were skipped, and when I rewind it freezes every time at the same point and always skips to the…
Heyho, quick question for you: Do you think it's worth investing in an extended warranty for an OLED TV? Or can you skip the extra cost if you're already careful with the parts? Manufacturer's warranty is 24 months. I would be happy to hear your answers!
Hello, my old Sony home theater system is getting on in years. I'd like to get a new one, but I can't find anything online. The combination with a radio, Blu-ray/DVD, CD, radio, and speakers. Is that so outdated that it's no longer available? Maybe you know more. Greetings Stefan
Hello, I have done a lot of research but each time I hear something different. Do you think a TV with a distance of 3 meters is sufficient or is it too close for a 77 inch TV?
Did you want to convert the value 6,8uF by a parallel connection or series connection of the two capacitors?
In the case of series connection, you should not have connected the two capacitors to minus.
Series minus minus minus I replace so for years bipolar capacitors it has never happened
Maybe this link will help you?

On one side of the capacitor lie -7v on the other side 10v it is an Elko without polarity
No! It’s a telescopic. After a rectifier, look into the supplement here not an alternating current all dc
“On the one hand, electrolytic capacitors have a high capacitance. On the other hand, they are polished and separate for AC applications.”
Is it possible that there is alternating current in your circuit?

Non polarized 6,8uf 25v
It’s bipolar elkos! Mean
Bipolar capacitors have no polarity. Therefore also the name bipolar. In contrast, Elko’s “Plus” and “Minus” have connections.
No way I’ve always replaced bipolar so 2 years ago never happened in other devices
