        No reasoning - it just works sometimes as does the IPA - perhaps you rubbed too hard.
        If the chalk doesnt work then I will be asking you to use the IPA. If I recall you said you used a cleaner that might not have been IPA?

            I try rubbing with isopropanol
            I have
            AE1050
            250329I(or 1)P
            E44242
            Maybe you can find something with that.
            the first and last are clear but the middle one the last 3 characters are not very clear

                    Monitor Audio RSW12 - Green light but no audio
                    by MOSSEP
                    Hi

                    Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

                    Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

                    The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

                    I have already tried replacing all of the...

                    Panasonic TX-P42G30E green light blinking, no video, no audio
                    by ItepK
                    Hey everyone!

                    I've gotten this TV for free, neither have it seen a TV repair man, neither have it been opened before.

                    This post describes my entire troubleshooting process of this TV.

                    When I turn it on using the ON/OFF switch at the side of the TV, the light rapidly flashes green, then it stays on, but it does not react to any of the remote buttons, side buttons, and doesn't play audio.

                    I've taken the unit apart, and I've started to check some voltages:

                    • On the P11 connector, there is 15V DC only for a brief moment, then it goes
                    ...

                    820-2610-A Sys onewire help, no green light. Please help from the gurus
                    by lcdcaps1
                    Hi

                    I have an 820-2610-A motherboard that has no green light.
                    I have noticed is when I do a SMC reset the light on the Magsafe blinks.
                    From My understanding, the sys onewire circuit is responsible for the green light on the magsafe
                    The sys onewire circuit on this model and others is more involved
                    I was hoping if anyone knows about this and how it works, can reply and let me know
                    I know this is an old model but I am sure there are people who still works on these or knows about them

                    I get 1.1v on the C7771 capacitor and will replace...

                    Help troubleshooting an audio problem with an RCA SGT-250 CED Player
                    by samson7point1@yahoo.com
                    The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

                    The player processes the audio signal using two different reference frequencies. The "R"...
