Try resetting the TV. Here's how to do it - Unplug the TV's power cable. Keep the Channel Down and Volume Up buttons on the TV pressed and plug the power cable back into the outlet. You will hear a click when you plug it back in if the reset is successful. Hopefully this should restore your video and audio.

Go into your menu and navigate to find Closed Caption then turn it off. That should do it!!!! Read your manual also, it's possible you might have POP picture in which it displays multiple channels when you change it. That feature should also be in your manual.

SOURCE: Sanyo DP42746 - Screen went black and no sound. Power light on.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

SOURCE: 26" Samsung flatscreen LCD doesn't power up

Just to be a little more detailed, since I just fixed this problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

Good day!
LCD screens have very thin fluorescent light tubes. if you can barely make out an image its most likely that the Power inverter board that powers the lights is damaged.

mark587, Did you shine a very bright flashlight 1" from the screen to try and see the WIN-desktop ?? Even though the screen appears BLACK. Your words above said: JUST CAN'T SEE IT Did you really NOT see anything? Have you seen any of the longer video clips of "LCD Monitor Disassembly" on YOUTUBE? Some BLACK screen "symptom" lcd displays can be repaired for less than $10 in parts. Capacitors! Also check videos on lcd repair. Then get back here to fixya and I or any of the guys can help you decide what to do with your display whoose screen is now dark and lifeless. After doing the YOUTUBE thing you may even tell us what you will do!!! Hope this was helpful. Yes we do want to hear back from you. please rate this response on fixya. I'm louie12fix on fixya or lmistyrel @ aol.com. Bye for now.

No image on the screen


missmai and guest, the ballast supplying the CCFL tube may not be working. PCB board is in the lid (Cover) where the LCD screen is mounted. Careful opening it...the membrane (loom) attaching LCD and PCB when stretch too much could render a blank or white faulty display.

If the store where you bought this player do not give service support and parts, you might just have to toss it and forget about it. There is nowhere to get it because the same model you have now is carried by another two (2) brand names plus Coby. Sorry...its the fact...i will let you know if there is a fourth brand.

Good Luck.
