See on ebay.com for used or new one of it as other trading sites sell quantities. Such as alibaba or aliexpress for chinese or amazon for better qualities

you can get cheap replacement boards for this tv via ebay,...........good luck,...

Yes, you are correct - S-video does not have provisions for audio - it is strictly video. To connect audio, you need two RCA cables, normally colored red and white, right and left respectively. Connect output to input from the source to the destination. The source is the DVD audio out and the destination is the TV audio in.

What kind of the connector for the sound are you trying to use? The TV has RCA audio outputs (Red and White RCA) and also optical out put for digital sound output.

Actually, you can do this. Just get an optical to RCA converter.
This looks like a good one: http://www.amazon.com/Cables-Go-40019-Optical-Converter/dp/B0002GV876/ref=pd_cp_e_2

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find.

There should be an AUDIO OUT left and right rca input/output plugs on the back of te TV; according to this, (http://www.bose.co.uk/GB/images/Lifestyle%205%20Series%20II%20Music%20System_tcm6-4083.pdf) the inputs for the audio are right next to the FM antenna port/plug so, if you have one of these; (http://www.inmax.ca/images/rca-cable.gif) just plug them in to the AUDIO OUT on your TV, and into the INPUT on your Bose system.

This can be repaired of it's later than a series 1. (not sure if the 1997 model was a series 1) Repair cost will be $225 plus tax (flat rate). Shipping is split between you and Bose. They give you a new 1 year warranty.
Otherwise, Bose can have you trade this in for about 25% off a new, current system.
-If this still powers up, make sure the small 1/8" portion of the input cable (plugged into "system control 1") is in good condition, because you may just need to replace that input cable for a no audio situation. If it's a different series, it will say "zone 1" I think.
In either case, you should call Bose tech support about this. (800-367-4008) Make sure you're with your system so they know what series of LS5 this is.

audio has to connected seperatly.vs 2 is for video connection only..Bose is a ripoff.... u pay all that money and you need a seperate audio connection plus all those wires..it isn't worth it and regret i bought it.
