42 inch Hatachie Ultravision model 43UWX10B and

The magic focus will stop if there is a bad sensor and or a problem in the convergence circuit.

This set uses two STK-392-110 convergence chips--both along with any of the resistors that protect them need to be replaced and the set adjusted--I have repaired hundreds of these sets----

Confirm model number----and if you go into the customer menu and either red or blue will not move in any or some direction--the chips have to be replaced---LET ME KNOW WHAT YOU FIND AND I CAN GIVE YOU FAIRLY DETAILED INSTRUCTIONS ON WHERE TO GET THE PARTS AND WHAT IS INVOLVED IN THIS REPAIR.

I am here to help people--

Thankyou for your help ive took the back right off and theres 3 lamps red green and white, i bought this samsung 42in rear projection 2nd hand it worked absolutely fine the first nite i got it then...

Cheryl at a guess i would say that was why it was sold. It has an intermittant control board fault.

Now these often extend beyond just the one board ( there are 3) Opening the TV up is a risk to you as not only does it have scatter radiation type X but it is the HIGH TENSION area where severe burns and electrocution is the risk. Call a professional to fix it. We have people on here all the time trying to do this on the cheap, not many suceed as often they think that just swapping the boards out will fix it. Rare! Most times it ends up costing 3 times as much because they dont have the knowledge, essential tools or the skill to tune it properley and they end up fritzing the board again or blowing the expensive lamp.

Thanks for using FIXYA Please rate oure help to keep the FREE service online++++
