Question about Sony DAV-S300 System

1 Answer

Audio on spekaers out, but not on AV output or headphones

I have opened the DVD player, and found that a chip has been blown. It is one of three, a TA2020-020, digital amplifier with two channels. I can try to replace it, (32 legs!!), but I am trying to figure out why it blew so that it doesn't happen again. What is also funny is that the other four channels from the other two 2020 chips are also silent, but I suspect that the FAULT signal from this one is keeping the MUTE input on the other two HIGH, and that is why there is no sound on any spekaer. Must I take a chance and just remove this chip, and see if the other channels work? The chips are located on the Power board, the complete board costs US$ 264.05 which is a bit ridiculous compared to a chip that I can get for $17.00

My advice is replace the complete board then you will have no more problem.although 17.00 dollars compare to 264.00 is ridiculous it will cost far less when you multiply big numbers by $ that you might end up spending more than $264.00

How do I connect my Sony soundbar ht-ct 260h to my blu ray player etc, I have no optical port or arc hdmi port,at the moment connected through the audio lead to soundbar & tv ?

hook your dvd player up to the tv via hdmi, then take the optical audio output from you tv to the soundbar. Make sure to enable to audio output jack in the tv setup menu as some manufacturers disable this jack by default.

I have a composite AV cable, but i can't connect it between my bose lifestyle 48 and my Macbook air, i mean sound from itunes doesn't works

Just take an audio cable with on one side a 3.5 mm (headphone) plug and on the other side 2 normal audio phono plugs.

Plug the 3.5 mm side in the headphone output of your MacBook and put the other side in one of the inputs of the Bose system.

I have a Coby dvd 505 home theater system and it's playing dvd's only in black and white Any suggestions?

There are a few possibilities. 1) You have the system on wrong broadcast system. Press the TV.Sys button on the remote. (In the US, you need the NTSC (analog) broadcast for older TVs). If you have lost the original remote, you need a replacement that matches the feature. See for a substitute remote. 2) You have mismatched cables/inputs.

For the second issue, a composite video cable could be connected to a component video input. If both devices have component video, get a component video cable (red, blue and green for the video, separate red/white cable for audio); it isn't included with the player. Otherwise connect to the composite (AV) connections on the TV (yellow for video, red/white for audio).

If needed, you can reset the player as follows:
1) Open the DVD tray.
2) Press the "Setup" button.
3) On the "Down" arrow, press it three times.
4) On the "Right' arrow, press it once.
5) On the "Down" arrow, press it three times
6) On the "Right" arrow, press it once, then press "Play/Sel" button.
7) Press the Setup button to exit.
*The default setting will take affect as soon as you press the setup button (step 6).

I hope this helps.

I have an lg lcd mod#lc427d hdtv how do i hook up an rca rt2280 system to it. i have a dvd player hooked up to tv now using hdmi cables, rca av reciever does not have them...

You can check your dvd player for a coaxial or an optical sound output, then you can plug it directly to your receiver. Those two are the best options after HDMI. Another option is A/V RCA type cable, you´ll need 3 stereo A/V wires, in order to connect the 6 channels. Remember to uncheck the HDMI sound output option on the DVD menu.

Volume Problem with my TV and Home Theater system

I had the same problem with mine.The solution I found was to use an optical audio cable rather than the red and white RCA audio jacks. Hope this helped.

No Sound in any mode

I had the same problem... but I knew that my 2 yr old had been playing with the headphone jack on the BC-150. Evidently, the system thought that headphones were still plugged in to the port on the front right of the unit, even though none were present. The solution that worked for me was to take some headphones, plug them COMPLETELY into the system (another set of headphones would not insert all the way, so I found a new set and used those to completely insert into the headphone port) while playing a CD and listen for a few seconds and then simply unplug them. Viola! Sound came back. Hope this helps.

Koss Ks4102 video problem

You have chosen the progressive scan option. In this option you will not get a composite video out to your TV using a single cable. you need to switch off this option by connecting the DVD player using three single cables namely Rr, Yy, Bb. this is possible only if you have this input option on your Tv. once you do this you will be able to see the display correctly and do the changes of switching off the progressive option. refer to the manual it is explained
