Re: Sony MFM-HT75W 17in Multifunction Display

Hi, I was able to fix my set by changing only three out of the six capacitors between the heat sinks opposite the plug on the board. I noticed under a microscope the caps looked a little puffy, but not much, and I checked them with a capacitance meter, but they were in tolerance, but decided to change the three closes to the edge of the board with a 1000uf, 50v, 1000uf 25v and 1000uf, 50v with the one that is 25v going in the middle, I didn't have another 1000uf,50v for the middle one. (sometimes you gotta use what you got to get what you want) So I powered my set up and it stays on . I hope this helps. I may go back and replace all six with 1000uf, 50v, but the space in there is limited and those are some large caps. I will wait until the set acts up again before i do that. I am satisfied with it for now. Again I hope this will help with what you've got going on with yours.10_25_2011_8_27_53_pm.jpg

Display went dark/black- symptoms point to T-con board but after 20 minutes, display lit up for 2 minutes then went dark again. Same thing happened again after next 20. After 60, display stayed on

Hi there,

I was a Samsung tech for 3 years, and T-cons are a common problem. But it sounds like a loose wire to the T-con, I have came across the same issue in the field. I would break it apart and look for a loose connection.

Why does my kinivo bth220 headphones have a flashing red light on them no matter how long i charge them and they will not turn on

The batteries won't charge. You might want to google around for replacement batteries.

First I'd try a factory reset. PRess the +, - and multifunction button for 6 seconds until the blue light flashes and it shuts off. When you turn them on next, it's in pairing mode and try again.

When i turn on my compaq laptop, why does it show a blank screen and shut on and of on its own?

its overheating or you have damaged windows. if you see the windows screen, try pressing F8 repeatedly as soon as you power it on and you will see a menu where you can select safe mode. try it and see if it starts, if it wont, or keeps restarting try to boot with a op sys cd just to see if it stays on, if not its the heat. if it does its your windows files and you must reinstall
