Agree with mrburns42.

My suspicion is that IC1 is probably damaged and should be replaced. D1 and D2 are unlikely to be damaged, but just to be sure, you can use your multimeter to measure the diode forward voltage on D1 and D2. D1 (R3000) should be somewhere around 0.8V to 1V. and D2 (1N5819) should be around 0.1 to 0.2V. If not, you should replace them as well.
