Thank you for using Just Answer, My name is Carl and I will try to help you with your question.
Does your tv have no sound on all inputs?
The fault with your tv could be caused by faulty capacitors or a faulty amp IC, I have come across other matsui tvs with no sound and this was caused by faulty capacitors.
If a capacitor is faulty they sometimes swell up and instead of having flat tops they tend to get domed tops. It would be worth visaully inspecting the main board of the tv to see if there are any capacitors with a domed top.
If you could send me any board numbers that you can find on the main board I will hopefully be able to help you more.
