Question about JVC AV-48WP30 48" Rear Projection Television

1 Answer

Laptop screen has been invaded by green and red/purple germlins

Turned on laptop instead of normal black screen with prompts in white, it was bright green. As it should turn to all blue, the blue did not expand to the full screen, instead a CD looking graphic was in the left upper corner and the bottom of the screen is a horizontal band of stripes in blues, reds and purples. The Gateway graphic is a strange blur. Other than red dots in odd spots on this screen as I am typing, the laptop works. Never had a problem like this in thirty five years of using computers. Is this a sign this laptop is not long for this world?

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....


Howdy;
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.

I cant get the color right. its to red??? any help? i did notice with the back cover off, there are 6 adjustment screws


yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!

Toshiba TP43h60 - Wondering what the dials are for


You are describing the MASTER SCREEN/ FOCUS CONTROL BLOCK---black with six controls--three are red, green and blue focus--the other three are screen controls--red, green and blue--- the screens are adjusted so with the color off you have normal brightness and a black and white picture--

They have nothing to do with any Convergence problem and unless they have been tampered with rarely need to be adjusted---

Let me know if this helps you AND IF YOU HAVE ANY QUESTIONS OR NEED ADVICE--LET ME KNOW.

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

Red , Green And Blue.


Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.

Green semi-circle of lines on Samsung 55" HDTV (projection)


I believe i have the same problem myself. When my TV is on any of the Component Inputs without my DVD player turned on i usually get the normal green screen. But now that is a dip in the green at the top of the screen from the top left to almost the top right and black pushing down on the dip. Almost like a green curtain was sagging at the top and you can see the black behind it. It does this on every input and distorts every picture you see. The distorted picture has all the green slightly off from where the rest of the picture is and where the dip at the top of the screen is there is somtimes purple instead of black.

I know the basics of how the picture gets onto the screen and its my guess that the Green "gun" for lack of a better term and somhow come loose, or been missaligned to a great extent. I would love to find an answer to this problem, and anyones best guess as to how much a repair man will charge, just so i know the ballpark.
