Question about Sony Bravia KDL-40V4100 40 in. LCD HDTV

1 Answer

Sony Bravia - sound pulsates off and on - several minutes on and then 10 seconds off. We checked cable box and HDMI cord on another TV, and sound was fine, so narrowed down to the Sony Bravia.

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.

SOURCE: Sony Bravia KDL52XBR5 picture blanks out using HDMI port

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).

SOURCE: Sony Bravia model #KDL52WL130 worked

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.
Solutions?
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

Your PS3 working doesn't mean a thing for the cable unless you are using that cable for your PS3. I would bet you have a bad HDMI. They are pretty sensitive to being bent. Try replacing that first. The other thing to check is to first make sure you have the proper input selected on the TV for where you have the HDMI plugged into on your TV.

you may have to set the input value on the bravia for optical on the input from the cable box. sometimes there is more than one way for a particular input to receive an audio signal, you may have rca(red and white), a black or orange rca type for digital, and then the optical. i would suspect you have to tell the bravia how the sound is inputed into the bravia. also , just a thought.... on the cable box there should be a volume control on the front of the box........ make sure the cable box volume is ALL the way up (it is the preamp volume).

Periodic tv screen blackouts


The problem is your cable box. I know you said you replaced it, but I work on TV's everyday and, sorry to say this but cable box HDMI outputs have serious issues, like no or intermittent sound and video. I have seen customers exchange their cable boxes 5 and 6 times and still have the problem. Your best bet is to use the component outputs of your cable box, visually you will not see a picture difference between component and HDMI when using a cable box. Your other solution is to get satellite; I have NEVER seen an HDMI issue with a satellite box

Our Sony (almost new) is experiencing sound problems. The sound go off and on about every 10 seconds. Cords appear correctly connected. It sounds as if its coming from the television.
Can you help with this problem?
