If you have a multimeter you can check a couple of things.

I don't have the service manual right now, but will by Monday. So if I am wrong about anything please forgive me I am working off of memory and it ain't so good anymore (LOL)

First look at the amplifier board and the regulator board right in front of the amp board. You should see some components that are about the size of resistors and are yellow. Those are fuses.
there may be around 6 of them, give or take a couple, and spread out across the board, most in one area on the regulator board.
With the power off you can use your multimeter and check for continuity. Set the meter to measure ohms in the lowest setting. They should all measure very close to zero ohms. if any of them show that they are not close to zero ohms and they are open, they need to be replaced. I will get you the part numbers Monday if you need them. It is important to replace them with the same parts. After you get them replaced, you still may have problems. Fuses open for a reason, hopefully it will just be something minor like a little power surge or something and it will be fixed. If the unit goes back into protect (shuts off after you turn it on) you may have a bad amplifier IC.

If I remember correctly this amp uses part number PAC007A for the amp IC. It could be another, but I think thats it. The best way to check the amp IC's is to have the unit powered on and check for any DC offset. You can do that by checking the big 5 watt ceramic resistors for any DC voltage. They will be located right in front of the amp IC's and are white with 3 leads each and are rectangular in shape about and inch or so wide. Be careful not to short the lead to your multimeter across anything and make sure the negative lead is grounded to the chassis of the unit. If yo measure anything above about 0.05 volts on any of those leads it is abnormal. if they measure a large voltage like 40 or 50 volts the amp ic is bad for sure and will need to be replaced. Most times when they go bad all yo need to replace is the amp ic. sometimes the 5 watt resistor will open up as well. you can check those by measuring with the power off the resistance in ohms. Put one lead on one of the outside leads and the other on the other outside lead. It should measure almost like it is shorted. They are only 0.22 or 0.33 ohms, it is labeled on the component.
If you need them I can get that on Monday to.

Let me now if you need more help and don't forget to give me a good rating if this was correct.
If I was wrong, forget you ever seen this post (LOL)

I have a problem with my samsung tv and my PS3, when i try to be on HDMI... All this time (for about 1,5 year) it worked perfectly, but now it doesnt! The tv has a "No signal" message and...


It is possible that your PS3 has "Forgotten" its HDMI setting. Please try the following to see if it fixes your problem :

Step 1. Turn the PS3 off into standby (red light on)

Step 2. Press and hold the power button. It will beep when you first press it then beep again 5 seconds later. Let go of the power button when you hear this second beep.

Step 3. Wait for the PS3 to display.

Do this with the HDMI lead connected and hopefully it will sort it for you.

Hope this helps

Red light comes on but the shuts off?


Mine did that and it really pised me of, sony told me to turn the power switch onthe back of the console on, when the stand by light comes on to push and hold the on button for at least 3 seconds until you hear a second set of beeps. This however didn`t work so I sent it back to Sony Australia and got it fixed up no worries.

Thomson DTI6300-16 digital TV recorder frozen, red light on constantly, no resposnse to any commands. I think it needs a factory reset - how do I do this?


Try Resetting the box to its factory setting:
  • Menu > Setup > Help
  • Then press the Green Button (Even though it doesn't show as an option)
  • Then press the Red button for a full reset
Warning: You will lose all data on the Hard Disk!

I did this when mine wouldn't record anything and dumped all my pre-recorded programs.
Worked a treat.
