My Toshiba Regza can run for about an hour before the sound goes on it..it gets very loud and all it does is make distorted loud noises.

the reason for running an amp is becauze ur running your volume so loud you are getting distortion. Btw, its the distortion that damages speakers. If your happy with the sound then you dont need an amp. If your running your radio "full tilt" to get your sound, think about adding some power.

its better to send it to repair shop

It may have dying power supply due to bad DC filter caps, leave it unplugged until you have it fixed, otherwise you will cause more damages to the circuits.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

This sounds like what may be causing it is the cable going from the tv to the receiver box. If it is only happening on the sat channels, you know that it's not the tv. I would replace the cable, if that does not work, then it may be that the receiver needs to be replaced.

Try unplugging the right speaker and plugging the left speaker in the right port. If the speaker still sounds distorted then you know you have a brocken speaker. If it sounds normal then we know its not the speaker.

Take it back where u buy it,talk to the store for a replacement,if possible.Or call Toshiba,talk to customer service,describe the problems,ask for a warranty repair.The Tuner board is is the board where the coalax broscast tv signal comming in to this board.It have faulty componnents on it.The board should be replaced.So get the tv replaced buy the store or waranty repair by Toshiba.

check your speaker speaker inside and check the capacitor inside too make sure they are good and working well.

This could be the speakers are vibrating onto the casing and need padding out more to prevent this.If this isnt the case, you may have a sticking coil on one of your speakers..When the sound distorts, remove one speaker in turn to see which one(s) are the offending unit(s) and replace. Is there a buzzing noise coming from the speakers especially in low volume? If so then you may have a faulty capacitor in your power supply producing hum on sound. Hope this helps :)

It's in the repair shop. I'll write back what the problem was and how much it cost to ship.

it is possible that your speaker system is not so good, and got a busted sound when it goes loud.
