New to the forum. One of my PS2’s (EU version) stopped working suddenly. Sound was very thin and low volume. It also smelled like something sythetic had melted. Volume didn’t respond anymore.
When having a look inside, my tech sent me these pictures. Three resistors look burned. One is for sure (R301), the other two (R214 & R215) are also suspect to be failing.
First picture (the white paper) are the values he measured on R215, R214 and R301 [can’t post pictures as a new user]. The pattern can’t be seen clearly anymore due to the heat they have endured.
Does anyone have the values of what they need to be replaced with? I suspect R214 and R215 should be the same value, but they aren’t anymore.
I asked the local distributor for info, but it’s out of warranty and they don’t have schematics. As they’re quite far away, I took it to my amp tech. But he’s not familiar with these devices.
I sure hope someone here knows how to deal with this and can enlighten us.
I took these pictures from my other PS2. Does anyone know the expected Ohm values? The ones on the white paper are the ones we measured on the failing PS2.
On the power tube board, you need 470 ohms, 2W in two places.
You may have had a bad power tube there causing them to overheat.
On the rear panel board, your unit was probably fitted with a 680 ohm 2W, with an associated 68 ohm 1/2W further down where it cannot be seen with the naked eye.
We’ve changed those values to 6.8K 2W and 680 ohm 1W and recommend you do the same.
