Hello friends of the forum, it turns out that I get this sony team that sounds all gangous and distorted to turn it on and during this ice cream, but shortly after being on and heating a little the stk403-130 is composed and sounds good, I thought it was a False contact, but when I checked it I did not find cold welds, I tested all the voltages according to the stk diagram and they are fine, provide the resistors and measure me well, I do not want to change this stk because it is expensive, I measured some filters and apparently they are fine, If someone has had this fault please can you tell me that it may be failing or how or that I can adapt it so that this fault disappears, since once this medium is hot, the amplifier of this equipment works well.

mother capacitors from the source of the outputs there is no more where to catch if you change them and the stk continues to heat up, logic is already damaged

Hello friend thanks for answering me, notice that I turned on the equipment and since it was frozen I presented the distortion and then I turned it off immediately and warmed the stk directly with a hair dryer and turned it on again and it worked perfectly, then something froze or does not activate within the stk, but what can I do to not change it, is there a way to adapt a resistor or filter to activate it when it is frozen

Do not use a hair dryer for that because you believe the components are static, what you ask if it is possible but in the end the stk will die! put a resistance of 7 watt directly to the alternating with a switch so that it works as a hot plate, what you need is to be ingenious and stick it to an aluminum foil and add it to the stk or in the case to the heatsink as close to the stk, but you should take into account to cut the power when going to use the equipment
