Hi All
Wonder if any one could help with some info on this set ?
The original fault was no sound or intermittent sound. Now I know this was a faulty ic u168 audio amp chip as stated by Tom66.
And as he said you need to remove this with a heat gun.
Now I proceeded to do this with my work station heat gun and was being as careful as I could, but unfortunately a couple of the tracks got damaged !!
Now I may be able to repair them but it will be very very difficult ?
But before I attempted this I started a search on eBay to see if there was a replaceable board available ? And yes there was but they were a bit expensive at around £25 to £30 .
But on a more intense search I found a identical board that looked exact in every detail but was from a different model TV. The board is from a Techwood 40940 FHDDIGITAL at a reasonable price.
So I sent for it, when it arrived I compared it to the original board and it looks exact, So I went ahead and installed it.
When I switched the TV on all worked ok good picture and sound.
But when switched on the sound bar appears on screen and travels down to zero sound you can increase the sound on the remote by holding your finger on the v up button and pressing the ok button when it is at the desired volume.
When you go into the menu and go onto picture and try to adjust any of the picture values :ie colour/brightness/contrast when you enter these it does the same the bar comes up and travels all the way to zero !!
The set works ok nice picture and sound.
I can tune in Freeview channels although only using a portable digital Arial that seems limited and have also tried the hdmi connections using a firestick and this works fine.
What I think is my problem is maybe a software issue or would I have to set anything in the service mode.
If any one could point me in the right direction to sort out the menu and volume issues it would be most appreciated.
