Question about Sony Bravia KDL-40V4100 40 in. LCD HDTV
Actually try one more thing before concluding that there is something wrong with the sound board or one of the wires in it on this Sony Bravia television. The cable box settings might not be just right for this television. Are you currently set to pcm or bitstream on this cable box? pcm might also be displayed as 2 ch 48 or 96 khz. Play around with the sound settings and see if one or the other will solve this sound issue before writing off the television.

I think this has to do with the cable box not liking the encryption thing going on with the sony tv. The cable boxes probably don't understand it fully and therefore you have intermittant problems. I would just use component inputs. Which are analog and no encryption problems. I hope this was helpful. I bet it doesn't happen using a sony DVD Player or a blue ray DVD Player either. Sony, Sony, Sony.....Good stuff...but they have their moments. Let me know if u come up with a fix for this and then i will post it on my fix it list.. Thank you again..GURU JAY

The problem is that, according to the specs for that TV, it doesn't support 1080p.
That's a 720p television you've got. (Specs here)
While the specs say that it supports 1080p, the resolution says it supports 1366 x 768, which is only 720p, not 1080p or even 1080i.
You may want to contact Sony for clarification, because their specs for that tv are contradicting each other.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years, some sooner, because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
Hope this helps
