Re: 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.

I have a 52 in. Sony HD ready rear projection tv and recently sometimes and I say sometimes because this happens randomly but the screen begins to flicker a green tint and then it shuts itself off and the...

Some of the early sets had this issue--they had bad picture tubes and set will turn rather bright red, green or blue and shut off.

The tubes for those sets (what model do you have?) are no longer available.

There may be a simple way to resolve this at least for some time depending on the model number--it will require no parts replaced and only a screw driver to adjust something in the set.

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....

Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.


Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

Magnavox rear proj (model# 8p6044 c102) pic is cloudy/green tint

Yes the coolant gets crud buildup in it over time which will cause the color and clarity to get very poor with obects that will glow around certain bright ojects. You can get the Phillips CRT coolant replacement kit from which has the CRT coolant for all 3 CRTs and also includes the Cd with instructions on how to do the replacement.

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....

Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

The only time I have had issues like this was because of the Component Cables not being in the right position (the Red and Blue connections switched), or a bad Component Cable where the Blue Connection is not receiving a signal. Swap out the cable to be sure and double check that it is properly installed. Green to Green, Red to Red , Blue to Blue.
Hope this helps,

Green and pink shadow on my samsung 55in proj tv what can i do to fix it. i all ready fixed red and blue line but green is way off and i dont see any way to fix it

hi, this is the early signs of convergence board chip failure. you will need to replace this board in order to correct the collaboration feature. the convergence is responsible for regulating the RGB stream in you set. if it is malfunctioning, you will not be able to regulate the red blue green streams.

The APEX and most rear projections are notorious for poor solder joints. The convergence circuits on your TV get very hot and the solder joints weaken over time. In your case, the convergence STKs are the large chips mounted to heat sinks right up front on the left hand side circuit board. Remove the board and resolder the STKs using a good low wattage iron. If this doesn't fix your problem try replacing the STKs. They aren't that expensive. They have 15 or so legs so you'll need some skills removing them. Good Luck!
