The colour has orange and yellow tones I cant remove


Have you tried cleaning the screen? I smoke cigars, so I have to go around compressed-airing and wiping stuff down constantly. Screens look yellow/orange if I let it go too long.

Picture Greatly distorted all of a sudden by many yellow lines


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

DLP TV: Left half normal, vertical 6" band center is gray, right half almost black. What's wrong?


No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.

Apex rear model?


I would say it's a adjustment you will need, is the convergence aligment ok, to adjust this you will need to find the adjusment block in the front, this is a black unit about 4" x4" and has lot's of wires that comes in.
On this block there will writing on it focus, and screen, well your half way there.
Adjust the green screen control downard to see if it adjuses your green problem if it does, here how you adjust the rest.
First go to your menue, turn the colours off. yes off.
next put contrast to max.
next turn your brighness to 40%
Nest ajust the screen control until you no longer see any trace line of the colour you or seing so that at the end product you het the best black and white picture you can. This will give you the end resolt for best picture posible.
Adjust the other colour after, to see if you or close to the corect adjustment go back to the menu and turn contrast down you shouldn't see any trace line.
Another problem people don't understand this unit have to be clear once's every 2 years.
This I won't explain it's a very long process if done right . Rear projectors has to be clear because with time you will notice the picture looks like you have catarack. or white filtering of the picture. This is when you know it need's cleaning, I do it all the time when I go to customer home, yes I do house call's. I think I'm the last one out there, most shop what's the tv in the shop mostly to be able to control the price there about to hit you with and if the customer doesn't pay there just sale it, they have the control and not you.

I hope this help, keep in mind it's very expensive to have tv repairs, but you have to pay, this what keep's tech going without them, well you can just imagine.
