Question about Sony Televison & Video

1 Answer

How do I fix the sound and tuning on my Sony Bravia KDL-40X2000?

The TV turns on and produces a picture. It has lost, or can no longer decode/tune/receive digital signal from the aerial and it no longer outputs sound from its internal speakers or headphone socket. It displays images from the my Sky box and HDD/DVD recorder/player. The volume is turned up, it is not on mute. I have gone through the menu options and tried a factory reset. I had noticed it occasionally flashed red several times upon start up but did not notice it when I turned it on and discovered the problem today.

Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. Surf the site with patience.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

    I took the back off of the TV to look at the circuit boards to see if I could see anything obvious (ie blown capacitors) but did not see any. On turning the TV on today, the red power light flashed 6 times, paused, and then flashed 6 times again continuosly. I was able to get the TV to turn on by pressing the power button on the TV itself switching it off and back on again. Still, the video works but the TV will not tune or play sound.

SOURCE: Unable to Tune TV to Sky + RF output

Hi.

The problem is that the modulator output frequency of your sky box is exactly the same as for example chanel 5 on your terestrial aerial.
You need to change this number to a different one thats clear of local terestrial transmissions


1) Select the Services button on your Sky or Sky+ remote control.

2) Type in 401 [select] on your key pad and you will get to the installer menu. You cant gain access to this via the drop down menu as it is designed for the Sky Engineer to use.

3)
Select Option 4 to configure the RF outlets on your Sky Digibox.

4) The option RF Chanel Number change this number from example 35 to 60 .
You may need to do this using other numbers 26 34 55 etc
Every time you alter the number store it then try & tune TV to sky.
Any other sets in the house connected by RF leads will require retuning for sky.
Save new settings and you should find that your RF outlet to TV works fine.

SOURCE: Hi, I have a Sony Bravia

am having same issue, and this is what I have learned, so far: Apparently, some of the earlier Bravias (mine is a 2006) has an issue with the F1 and F2 fuses on the Digital Tuner card. I decided to bite the bullet and open up the tv. The back came off fairly easily, and the card is in plain view. I believe it to be the same card that the coaxial connects to. There are two data connectors, top and bottom. after you free the card by undoing the screws, you will want to disconnect the bottom first by simply depressing the center of the connector and gently tugging to disconnect. The top data ribbon is a bit strange... the top of the connector rocks to one side, and the ribbon simply falls out. My card is part number A1164341A and is used on several of the tvs. I found it on Ebay for 10 bucks, inspected and tested. I just bought the card, so I don't know for sure that this is the problem, but I am fairly confident from what i have found out from researching the problem

Sony bravia kdl-52w3000, turn tv on, no picture or


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).

Sony Bravia KDL 40X2000 HDMI both cutting out


Sounds like a handshake problem with the HDMI outputs on the devices. I have never seen BOTH HDMI inputs have the problem. It could be a problem in the TV where the HDMI signal is processed or the HDMI jacks may have been stressed and this is why you have an intermittent problem. By stressed I mean that the jacks have been bent by inserting the cables wrong or pulling up or down on the cables when they were plugged into the unit.
