HCL4715W Green Color intermittently projecting

When TV is on, the green color sometimes isnt being projected or very lightly as there is a heavy red tint. stuff that is supposed to be normally green is very dull or gray colored. Occasionally i will see a light green flash cover the whole screen and the picture will be normal again. It is intermittent and goes from normal to green not working frequently. Lots of light green flashing. Had the convergence board replaced last year. When green is out, perfect focus does not work and unable to do any green convergence from the menu. I have tested it with my DVD player hooked up and when using that it displays the same problem. Also when i watch cable through direct tv, i see the problem. I havent got to the back yet to test the connections. I was in the back a week or so prior hooking up a Wii i just bought. I had to pull out the TV only slightly to do this. Not sure if the movement or loose cables could be doing this? I was looking at the back of the TV yesterday and noticed that when the green is apparently gone, i am unable to see the green being projected at all from the back. I can see the blue and the red projectors throwing off color, but the green projector is dead. I am not sure the technical name for the part. IT looks round as is between the blue and red. I also have come to notice that if the TV is off for a while then the green works fine for a couple hours. AFter it has been on for awhile is when the green starts flickering on and off. I have tried hitting the side and moving it around and it does seem to have no affect on having the green come back on.

    Also, for the last week now i have not experienced any adverse picture. The TV is working excellent now. I have watched 2 full length movies without the TV losing its green. The TV has been on for over 4+ hours at a time without any issue.

    So i am not sure if something was just loose or something is on the fritz.

It sounds like the common problem with this set. It is an intermittant picture tube, or there is a loose connection on the green drive board on the green picture tube. Try lightly tapping all around on the green drive board while the set is on and see if you have any change. BUT BE VERY CAREFUL! Lots of high voltage on the board. Also use a plastic or wooden device to do the tapping. If you do great, you know you need to resolder the connections on the board or clean the CRT socket on the green drive board. If there is no change, I would bet the green CRT is on its way out. But try tapping the green drive board all over as I said before, that is a very very common fault with these types of TV sets. Good Luck

Our samsung HCl4715W tv is all connected right but our picture is scrambled where you see double exposure and the color is off. Can not find our manual. any suggestions?


The problem of your tv is the convergence. Projection tv set has a 3 colors red,blue and green this 3 colors must be properly lined up to look the video normal. When this 3 colors is not properly aligned the video will produce a double image of color or like a 3d or wavy. In order to fix this problem you should adjust it in the menu program of your tv you should move any of the colors to up or down, left or right if you cannot align the 3 colors the problem is the convergence ic it must be replace. To locate the convergence ic you should remove the back cover of your tv but be sure to unplug your tv, you will see this ic attached in a large aluminum plate it has a marking of stk--- and followed by a numbers. or you could contact a service technician do do it for you and save you from stress. Good day and best regards.

I have a toshiba 65hm167 no red color on the screen


Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck
