Samsung HL-T6756 DLP TV Standby/temp light flashing and tv won't come on. I have replaced the lamp and the fan is working. Any suggestions?


Remove lamp and inspect the color wheel to see if missing pieces or shattered---it will also just before failing give a high pitched or fan like sound and if running too slow or not at all instant shutdown happens.

Its also possible if you bought a GENERIC bulb--and used original cartridge the new lamp is bad.

CAN ANYONE HELP i'm having a problem keeping the timer from going off and shutting the whole tv off. My kp-46wt510 sony widescreen from 2003 is doing the same thing, picture is bowed in the middle and...


Hi,

Most likely you have turned on the sleep function. 2nd button from the left on the top of the remote hand unit. Keep pressing until "sleep off" appears on-screen.

Or

Timer in user's menu is activated to turn off TV a specific time. Go to timer menu and adjust timer, then push cancel on the remote, this should reset timer to zero. Same with current time, adjust and select cancel, this should reset current time.

If you do not have the original remote, you are in trouble. Service tech will have remote.

When i turn on the tv there is no sound only clicking sound and no picture. then it atomaticly turns off. also the lamp light flashing red? not sure what is wrong.


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.

Convergence


Have you tried to adjust the convergence in service mode yet?
If not here are the steps.
1) Turn the TV off with the System off (under flap of remote)
2) Press: Display, 5, Volume+, then Power. If successful, service text will appear on the screen.
3) Use 2 & 5 - to select the PJE category. Be careful, like your computer, you don't want to be adjusting the wrong screen.
4) Press 9 - to get to the convergence adjusting.
5) Press 6 several times to get the convergence screen of choice. (I like the grid)
6) Use the remotes arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color(Push it sideways or up and down and hold). Press 3 to change color to adjust(red, green or blue). When done, press center of joystick again, this will turn it back to white.
Note: Try to keep the grid even and square.
7) Repeat step 6 for all parts of the screen that need it.
8) Once done, you need to save your settings. Press: Mute,Enter. Then on the T.V. press "Flash Focus" (it will set it self)
9) Turn off Power.

I have a 56" samsung rear projection tv that won't turn on. the red standby light is lit and when i push the power i hear two clicks and the green timer light flashes quickly then the green led stays lit...


I suspect you probably have a bad LED assembly. It could be either the red, green or blue that is bad and give you the same symptom. The problem is locating parts for it as it looks like the light engine is no longer available. I would have a technician look at the TV to verify this and what parts are needed for repair.
