I have been given a Samsung SP42W5HFX with a conversion fault.
I bought 2 IC chips and took the board to a repair service to replace them for me (very cheap option)

After bringing it back and putting the TV back together.

The conversion is still miles out and has a wave in it at the top.

Anything I can do to sort this out?
Also where could I get hold of a service manual?

I have entered the menu with mute 1-8-3

and tried to adjust the colurs (did not do it for long, too scared...)

Any help would be most appreciated

Now have the service manual, and have adjusted, after turning off the red, the picture was clear (but obviously without red)

Does this mean the red IC chip needs changing again? although it has just been changed.
The red is miles out and makes a huge wave at the top

Thanks Trish
