Hi friend, I have a sony sound system model mhc-gn800 which came with the failure to protect it, I checked it and I realized that it is the ic 412-150 which was burned but also had the resistances of 100 homies 1 / 4w were burned unfortunately not aye of 1 / 4w only opened of 1w and selas I put but when the boy to chufar to the current it is very hot resistances of 100 ohm to 1w that I put that will be happening ayi friends

Friend checks the elements adjacent to the integrated, R511, R512 and R561.

Yes, I have already checked them and they are in good condition, but the R511 is also very hot and when I leave it on for a while, the current semester plans to burn the c501 | c554 c551 I already changed transistors but not aye the c1841 so I put the c2229 always the same thing happens

Friend of the integrated you removed you still have it (The one who brought the equipment)? It is rare that you are damaging those capacitors since they are the coupling of the signal to the input of the integrated.

It seems that you pass Olympic of my advice, 99.9% of the destruction of the main integrated of the source, the reason is destroyed is the main filter of the source of about 10 / MF / 400v ... 47 / MF / 400 volts. Anyway, you can do what you want, but this is my advice. Postata: If I previously replace the integrated one and I do not replace the famous filter that I say the integrated one has become bad again, (you have to change the IC + the filter that I have already told him.

Ok friend, this one has the 4 filters, the small ufdos and two grids, the two c596 q som of 2200uf at 100volts are 592b 3300 at 50 volts, the ic is not burned because it sounds at all 4 outputs but after a few minutes If the c551 c504 c501 c554 overheat, change all the transistors that are the c1841 but do not use them in the store so I put the c2229 instead of the c1841 but the same is still the case but boy change the source's lines to see what happens and I tell you, thank you friend
