    Called a mobile television repair man. He came over with the parts( two chips), replaced them and did the convergence auto focus thing and fixed it. Cost me $285.00 dollars to repair a 1,200.00 dollar set.

CONVERT 2D TO 3D


If you just need the basic 2d to 3d conversion, I think a high definition video converter is a great and helpful tool, which can satisfy your demand of 2d to 3d conversion.

The picture is showing a double image and is distored.


The problem you are refering to is more than likely a convergence problem. The convergence circuit in your tv is controlled by an IC (integrated circuit) stk392-110 and it makes the 3 colors (red, blue, green) line up/converge together to create a clear picture. You'll know when this part needs to be replaced because the picture you see is 3d looking and possibly bowed on the top or bottom or on the sides in any or all 3 colors.

My rca projection tv has blue and green images like a 3D picture would without your 3D glasses, a double vision image and no other colors


sounds like the sensors are out of focus and your red sensor isnt turning on. look in the back of the tv for a master reset button or in your menu screen some sort of "Flash focus" or "convergence". They will realign the 3 sensors.

I am seeing a double image whel I look through my binocular.


Hi,

Most binoculars should allow you to grip the two sides and pull them closer together to fit the distance between your eyes.. Have you tried this?
What you should see is the two images come together to form one.

If you have tried this already and you still get the two images then it's possible the model is just too wide for your eyes.. If they're new you could try return them for another type that fit better..

If this works for you then here are the instructions for setting up the binoculars to give you the best result for your eyesight..


This is more common than you would think.. Here's how to set up a pair of binoculars to suit yourself.
Any good binocular will be able to do this and the reason is to allow you to adjust them for the difference in strenght between your two eyes. I wear glasses myself and sometimes contact lenses so it's good to be able to quickly adjust them.

1. turn the binoculars over so you are looking at the underside.
2. on the eyepieces can you see on one eye(usually the right eye) a little plus - minus marking. The eyepiece should be able to rotate a little to each side of this marking.
3. Set the rotating eyepiece to the middle setting.
4. Look through the binoculars as normal and bring the two sides together until you form the two circles that you see into one.
5. Pick an object app 10 meters away.
6 Presuming that the adjustable eyepiece is on the right hand side then close your right eye, look at the middle distance object you chose with your left eye and use the central focusing knob/wheel in the middle to bring your left eyepiece into focus.
7. Now, close your left eye and adjust the rotating right hand eyepiece while looking at the same object until your right eyepiece is in focus.
8. The binoculars should now be set for the differences in strenght of your eyes and you can use the middle focus control as normal.

Most binoculars have a soft rubber eyepiece that can be folded back for people who wear glasses but I, like most people I know who wear glasses, find it horribly uncomfortable.

This method allows you to set them for yourself and if someone else uses your binoculars you can quickly reset them for you.

Hope this helps...


- Oh yeah, sorry, forgot to mention.. This set up is so you can use them without wearing your glasses.. Much more comfortable!!

POOR PICTURE QUALITY


The convergance IC's need to be replaced along with possibly a pico fuse in the same circuit.Theres a large heat sink with two IC's starts with a STK number,replace them and that should take care of it.

the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck
