Re: OSCON go BOOM!

You should see a 1 farad wired incorrectly. Black goo everywhere inside a Saab. One of the best installers I ever knew did it, was in a hurry.

Re: Cyber Acoustics MMS-20 amplifier blows speakers



Sorry that is just not correct. Underpowering will ALWAYS blow a speaker faster than overpowering. I'm not arguing that the speakers suck, I'm sure they do, but you cannot take a much larger mass and put it on a weak IC amp like that. I guess you will find out why if you don't believe me....

Re: Cyber Acoustics MMS-20 amplifier blows speakers

You replace some speakers that were likely 3 watt RMS with some that are 25 watts RMS. The amp TEA2025 is 2.5 watts. Theres no way in hell those drivers are getting enough power to move them correctly.

Re: Vizio GV42LFHDTV10A no pic, no sound, wont shut off

One thing you can try is to add more solder, wick it off with the braid then add a little more. Sometimes the solder is brittle and doesn't flow on the braid easily. Adding a little more will dilute it and make it flow better.

Re: Poloroid TDA -03211C- - - -Power Board IPOS 150 Ver. 1.8

Did you check the transistors? Doesn't sound like it but didn't see you mention it. It could be an IC as they can have issues with being intermittent.

So I have an NAD 302 integrated amp. It powers on fine but does not give any audio output. I have checked the fuses and the diodes. I have not removed the pcb and checked the transistors yet. I noticed some brown stuff at the bottom of the capacitors but I think it may be glue not discharge....

Works great. Thanks for the help.

Re: Poloroid TDA -03211C- - - -Power Board IPOS 150 Ver. 1.8

Nothing is wrong but they are 1.20 a piece so why not change them since they are known to be an issue on these psu. The fuse are the same amps, voltage and delay just bigger. There is definitely room in there.

Re: Poloroid TDA -03211C- - - -Power Board IPOS 150 Ver. 1.8

I have one of these tv's with the same issues. The previous owner tried replacing the caps but it did not fix it. I found the F2 fuse was bad. Does it matter if I replace it with a 5x20 (radio shack) and add my own pigtails? I am going to replace the transistors and plan on ordering the correct fuse as well but would like to get it going to make sure it works before I do. So would those larger fuses cause any issues? They are 3.15A 250v slow-blow. A veteran mentioned they were time-delay which i believe is the same?
