no corrosion that was a obvious leak with the c2 and c3 had that plastic black and the other one did look brownish - C7 330uf 25v which is to the left of the large white block resistor.
I went to Jaycar and got the part but the guys there tested the bridge on the board and they said it looked fine, I worked out the novice in me had the setting on the multimeter set to the continuity sound test
.
I watched a few more youtube vids and corrected my multimeter setting and did the check again. (test reference is viewing from the back of the board) This time doing the tests from the positive to the AC's got 583 on the bottom AC and 596 on the right side AC and obviously switch the leads and nothing. Now with the positive on the neg of the bridge and touching the above AC got 580 and then touching the left AC got 660 and switch the leads again and nowing. In the video it said readings should be between 400 and 600, one is a bit higher by 10% - is this still ok.
I looked on youtube to work out how to check the white block resistor which is rated at
5W 0.12 ohm symbol and then a
JI got the following readings with the multimeter set at the following ohm setting
200 gave 0.5
2k gave 0.001
sound test gave 001
would this suggest a possible problem with the white resistor not matching the 0.12?????
I will wait to do any globe tests until someone can confirm a possible suspect white block resistor
