    LAMPS ?

    I have no problems with the picture ever before.

    Are these lamps can be replaced? Do you have any idea how much they cost?

    Thanks

    You said lamps, are there more than one projection lamp? Please explain

  • AABBCCDDZZ Nov 09, 2008

    Can the three lamps be burned out at the same time?

    Is there any fuse that could be burned out?

    Not sure if it's the lamps, but if it is, they usually are several hundred dollars a piece. Is best to have a local repairman come out and test to see what component has failed.

  • Trevor Gordon Nov 08, 2008

    There are 3 lamps, one per each of the primary colors of red, green, and blue

    It might be a power module issue, best to have a repairman put a meter on it and find the exact problem.

Hi my TV is ghosting and I cannot change the blue on my convergence. It will allow me to go horizontal but not vertical to adjust. Is there a reset on the TV? Zenith IQB56W10 56 in.


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

The picture will go black and the sound will go out. At the same time, the green power inicator will flash. Then the picture and sound will come back on for several seconds and then it will go out again....


My TV had the same problem. I called Sony yesterday and they told me to reset the TV. I did so yesterday, and it seemed to work. Here is the transcript with instructions:
Please turn ON the TV. While holding down the RESET button on the Remote control, press the POWER button on the TV. The TV will turn itself OFF, then back ON again. Release the RESET button.The TV will go thru the initial setup, and should work normal.

Won't turn on.


hi,

try unplugging it and thn plug it back if the light comes for 3-5 sec. and goes off thn you will hear another click noise when it goes off. you never get a picture or sound.If im right thn there are several circuits in the tv that might cause this. the most common are the power supply and the convergence circuits. a cost of a repair for either will range around $400.00. this is a great model and well worth a repair.
good luck:)

Dont forget to rate me as fixya..

Samsung HCL4715W will not power on


At five years old, I doubt it will be worth replacing the power supply , a picture tube or two and possible the signal board. Cut your loses and get a new set.
