Question about Sony BRAVIA KDL-40V2500 40 in. LCD HDTV

1 Answer

Power and sound turn off after 15 minutes

After 15 minutes the power and sound automatically shut off. To turn back on I have to unplug the TV and plug it back in, and then the green light automatically comes back on without pushing the power button. It was supposedly repaired a week ago - some contacts were soldered, but has started to do it again. Anyone have any ideas.

    I have the same problem with my LCD tv. It's new and I thought it was the satellite receiver but the tech came out and replaced the box and it's still doing the same thing. The tv manufacturer's phone tech support had me unplug the tv for 3 mins to clear the memory from the motherboard of the tv unit and that worked for about an hour tops. Still not fixed...Please let me know if you fixed yours!

    Same problem but my red light blinks 9 times. Tech already replaced power board. Went out an hour after he left. Supposed to replace lcd panel next but he is just guessing! Any info would help!

    The Regulated 12 volt and regulated 24 volt supplies are both good. So are the 3.3 volt stand by voltage and the unregulated 15 volt supplies. The power light comes on and stays on but there is no picture, and the power button won't respond. If i unplug it for a couple of minutes, it all works fine untill i power it off and on without waiting for it to discharge enough. Any ideas?

Start with changing the capacitors that look bad on the PS board...I think you will find some that are bulged when you take the cover off, should be a easy and cheap fix

Loud noise then lose picture


The green power LED probably is merely indicating that power is getting to your TV but the internal power supply is failing as evidenced by the loud "pop".
