        That cannot be right for 46" screen.
        Per service manual page page 64 (BE2 board), the T-CON Voltage is 12V, it is fed to the fuse F4302 (3.15A) on the main board, the output of the fuse is fed to the switched MOSFET Q4308, the output (Panel_VCC) of the MOSFET is then fed to the LVDS connector to feed the T-CON board.
        So he can use 3.15 or 3.5A fuse for the T-CON.

            I've got the black screen and no audio too, I haven't tested the fuse yet on the t-con board and I was wondering where to get a replacement fuse if it's bad..

                Monitor Audio RSW12 - Green light, but no sound
                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...

                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...

                SONY KDL-52ex700: No picture, No sound, No backlight but gets Standby & Green light

                We came one evening & realized this problem when tried to turn on the TV (SONY KDL-52ex700), there has been, no sound, no picture, no click sound (for backlight).
                Here is the sequence I have checked so far.
                1. Pressing the Energy saving switch button, TV used to turn ON green light, get backlight click sound & used to show Sony logo with sound
                - None above happen anymore. No green light, No sound, no picture, No backlight
                2. Pressing the power switch button...

                Sony KDL-46EX640 Green power Light no picture
                by dcapper
                My friend dropped it off and asked me to look at it. Like the title says. The power button works. The TV turns on but no light no flicker. Nothing at all. Also, check out the grey wire. It's burnt. The board says it's the power wire to the main board. Any ideas?...
