Try mouser.com. They have a great variety of electric adapters.

If the TV has no picture or sound, but the led turns from red to blue or green that means the mainboard has sent the power supply board the start up signal. The first thing that needs to be done is the voltages need to be checked to the power board. Follow the steps.
1. Hold the (menu) and (vol-) buttons on the side of the TV.
2. While holding the (menu) and (vol-) button on the side of the TV you also need to press the (power) button on the side of the TV (NOT REMOTE).
3. When the blue light comes on and stays on wait 10 seconds then let go of the (menu) and (vol-) button.
4. Wait 30 more seconds. After waiting another 30 seconds you should see some type of picture appear on your screen. — If those steps do not work then you need to unplug your TV for 10 minutes then hold the (power) button on the side of your TV for 60 seconds - plug in and turn your TV on.

If those steps do not fix your problem I would check to see if your device is still covered under a warranty. If not I recommend www.tvrepairpros.com they will find a technician in your area to further assist you.

Re-check all of your wires between the TV and the system are fitted correctly at both ends. I usually concentrate on the TV first where I remove ONE connector and wipe it with a DRY lint free cloth and refit it, making sure it is pushed fully in. Then do the same to the next connector, (remove, clean and refit), and so on until they are all done. Then I move to the back of the TV and use the same method. Also do this to any DVD players and anything else you've got plugged into the theatre system. Once you have done this recheck all the settings on the Theartre system AND the TV as sometimes settings can get changed accidentally when changing other settings.

This item is not a repairable item. It is a throw away item There is a working one for sale on fleabay for R200. That is about £10 GBP. There are no service manuals or even schematics because when they failed under warranty, they were replaced.

Question edited for clarity. Does the tuner have an aerial connected to it? Also the Tuner would be better connected to an amplifier, not a pre-amp IMO. Manual and Service Manual https://www.google.com/search?q=Sansui+T-1000+tuner ..

perhaps a dealer .

It uses an SN-707 stylus. The cartridge is not replaceable. It just pulls off in a downward motion.

Hello Chris, try to clean the volume controls, balance, tone and switching keys, with some clean contact spray, be very careful in the amount you apply, always try applying a drop of the cleaner and watch if the noise level goes down If you do not achieve results, you should replace the controls that generate the noise Look for a good specialized technical service Greetings Franco Dosil Hola Chris, prueba limpiar los controles de volumen, balance, tono y las llaves de conmutacion, con algun aerosol limpia contactos, se muy cuidadoso en la cantidad que le apliques, prueba siempre aplicando una gota del limpidor y fijate si baja el nivel de ruido, si no logras resultados, deberias reemplazar los controles que te generan el ruido Busca un buen servicio tecnico especializado Saludos Franco Dosil

Sad to say it's likely to be 1 or more transistors in the power amp circuit, although there are other possible causes. Luckily the repair manual is available (hifiengine.com) and the power amp is built with discrete components, so it should be easily repaired Most common causes would be an output transistor or dry solder joint(s) due to transistors / resistors getting hot and cooking a solder joint or 2. Inspect all solder joints carefully with a magnifier, looking for signs of localised heating/burning and/or crysalisation of the solder. It's normal to replace output transistors as a matched pair even when only one has failed, to minimise distortion. Replacement transistors should of course be as close to the original specs as possible (or better) if genuine parts are not available. The bias will need to be adjusted as per manual (1.5mV emitter to emitter of output transistors). Good luck.
