A series of caps in the audio circuit are failing and need to be replaced. You'll need an esr meter to determine which of thse are failing and short of that I'd strongly suggest you have a tech repair it. It's not an expensive repair and I'm positive you would be much happier with the outcome.

I have a sony tv model kv-27v42 i have sound but no pictture and stand by light blinks what is the problem


How many times do this standby light blinks at a time of switch on? These blinks are fault indications. From the number of these blinks, you can get an idea about the faulty circuit section inside it. Count it. If you wish to get more details about the blinking codes to Sony TVs, check this link.

Blacks out for 1-30 min. then back on. Standby light blinks 4x


I would suspect the circuit board around the HV transformer area to have a crack circuit print. Also look around in the vertical circuit for interment solder connections. But only do these things if you have some knowledge of TV circuit lay out. If you do not feel confident then call a professional. No sense in hurting yourself or damaging the the set worse.
Hope this helps,

Sony 2167 No power on


I have not worked on your particular model. But, I have serviced many TV sets over the years. My answer will ge generic.

Check all the capacitors in the horizontal output stage and power supply areas for high ESR. All the caps that are out of spec must be changed.

The high voltage multiplier & flyback can also cause the fault you are having.

You have to consider that the DC voltages are not the only important spec that has to be met. There are also many power drive signals that work with reactive devices. If there is any defect in the critical areas there will be failures.

Sound goes off after 5 minutes


hi there, yes it can be fixed, hitting the unit means that you have a cold solder on the board. the sound is in the amplifier section, check some connection at the speakers and amplifier, a cleanning and a reheat of cold solder to the baord is required. ty

No Power on Sony TV


Be sure to use an ORIGINAL Sony transistor and be sure to resolder the pins of the small horizontal driver transformer and all parts connected to and around it, and your set should be fine.

Sound Problem


There's a possibility that you may be experiencing problems with the audio output IC -IC404 - All serial numbers produced until July 2003 might use one of these defective IC's. So if your set was manufactured before this date, that is probably the culprit. If not, and you have it connected to a cable box that has its own volume control, it could be that its volume is turned down and by turning up the TV's volume too high that you are getting this distortion. Hope that helps.

Sony KV-20FS120


It's normal for new sets, especially Sonys to do that due to some sort of gas build-up in the new tube. My set still gets a high-pitched buzz after power on and lasts for a minute or two before silencing. If the hissing continues when the TV is turned off return it to the shop ASAP. It could be a problem with the power supply, something getting ready to blow up. Good luck
