    If you turn your backlights down what effect does it have.
    Also if you turn off all the power savng and Eco mode settings does that help?

      Seems little improved, but it still does turns off whenever there us a black scene. Somehow if I can maintain that low voltage.

          Hi Sacrh
          Was your tv working fine now,even my tv (sony KDL 52nx800)show the same symptom has yours,when checked found 0.5a fuse was blown replaced and checked but still has the same problem as yours.pls let me know if it was solved.
          problem is as soon as you turn on the tv goes to standby mode and when press the power button the led turns green and back to red with 6 blinks.
          no picture or logo only sound for just a sec.
          opened and checked the led strip ,which looks visually good.

            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...

            Samsung UE49KS7000SXXH - fast clicking sound in standby mode
            by B0r1s
            PSU - BN44-00878A

            Symptoms:

            The TV turned itself off, and I haven't been able to turn it back on. The standby voltage was unstable and lower than it should be.
            A weak clicking sound was coming from the transformer.

            Video with clicking sound:https://www.youtube.com/watch?v=lAduhjNtqCA

            Progress:

            After the transformer, I measured four Schottky diodes. DM862C and DM864C diodes readings were 003 in both directions. After detaching them from the circuit and measuring them, DM864C was the shorted one. These Schottky diodes are SB550.I...

            Sony HCD BX7700dbi CMT flashing standby
            by rabbituk
            I have got a Sony HCD-BX7700dbi that isn't worth a lot but I'm keen to learn how to repair and would appreciate some help with my train of thought. The protection circuit is kicking in and the standby light is blinking. It goes into protection mode within a second of powering it on.

            So far the relay on the power board that enables the main transformer clicks on and then off when powering on the unit. Looking at the schematics, the permanently enabled power rail called 'unreg sub' provides about 13.5VDC. Where the power comes into the main board on connector CN303, there is a diode...
