TV turns off and green LED light stays on.

TV turns off and I hear a soft pop. The LED light stays on but no picture. I tried the self diagnosics by holding down the input and menu button for 5 secends, but nothing happens. The light just stays on and doesn't blink.

    The problem started 2 days ago. When this happens I'm unable to turn the TV off with the remote. I have to unplug for a few minutes, plug it back in and then I'm able to turn it back on with the remote. The TV stays on for a short time but then turns off again.

1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067002 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). 5. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 6. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001 7. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001

Since when this problem started.. Are you able to check it yourself..

otherwise take it to nearby repair shop for replacing the Fuse and check power Control & Supply board.

    Have you check the cable of TV if not broken from anywhere? You also need to check internally for the Power control (PCB) Board for any burnt ICs and Connectors.
    Note: Be careful during reparing Television as they contain Hazardous voltage inside.

When I turn on the tv all i get is the welcome screen, and it will not go any futher,there is green light flashing in front of the tv. and it will not turn off with the remote, i have to unplug it.


Hi Andre,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code to narrow down, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.
Regards,
Jdvillanueva

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.

TV picture goes out after 10 minutes of viewing with popping sound


It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.
Thanks,
Lee

Hello Fliper,

These symptoms denote a shutdown circuit problem, and a problem in the section of the TV that provides High Voltage to drive the raster creating circuitry. In your case this would be the DLP related circuitry this would include the light engine (white light blub/Color wheel drive circuitry or LED array, DLP chip and associated circuitry). In any event if you are not planning on working on this yourself (which I would not suggest for this type of problem), Have a qualified TV repair technician come over and examine the TV and give you an estimate on its cost.

I would also tell you to expect it to be rather high since for your description of the problem it looks like a light engine problem, however it could be as simple as a blown bulb or LED array. The Technician will find that out.

I hope this helps,
Thank you,
Shuttle83

Tv wont power up makes a noise but no picture


Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.
