Hi Ron, if you can see a picture with a flashlight your power supply is working ok along with the main board and tcon board, so were down to 2 issues, one would be the backlight inverter and that is part of the power board however that section of the board seldom failed, chances are your LED lamps have failed and need replacing.

    The LED lamps not working would cause the sound not to work?

    I missed the part of no sound, if you're on the right input you should have sound, sounds like more than one issue then

I have a Vizio LED TV model D50-F1 that the picture has gone out in. I performed the flashlight test holding a flashlight to the screen and can see the image.

This is a backlight issue, it is either the led backlights or the T-con board, further testing with a circuit tester is required to determine which.

Need help with tv issues. My tv turns on. But the screen is black. When i do the flashlight test i can see the picture. Would this mean it is my backlights? Any help is greatly appreciated! My tv is a...


Information for advanced users.
The absence of an image in the presence of a signal is often caused by a malfunction of the display backlight. Moreover, the problem can be both inside the LCD panel (matrix), for example, a malfunction of the LEDs( LED), and outside in their power source - the LED driver.
Without the backlight, you can sometimes see a barely noticeable image with a certain successful hit of external lighting on the screen.

Lcd tv screen goes black after a few seconds but sound still plays. The flashlight test will show the image for a short period of time but then it goes away and is completely black.

Hello... It sounds like you have a backlight failure, and the image going away during the flashlight test is due to the TV going into "Protection" mode. A service technician may be able to go into the service menu and clear the lamp error codes and get the TV working, or it may need the backlights replaced. I hope this helps...

Screen keeps t going blank but still have power

It may be the internal backlight that is failing. When the display has failed but still has power, take a flashlight and hold it close to the screen, move the flashlight all around the screen and check if you can see anything. The display will be dark, but you should be able to make out the image that is there with the flashlight technique. If you can see an image on-screen, then your backlight has failed and you will need to replace the monitor. Weather or not you see an image is not a critical issue, but a tool to verify if the backlight is off or some other issue is causing the problem.
Note, it may be difficult to detect an image on the un-light display, for example if you have a dark image as your desktop background. So make sure to fully scan your display (top to bottom, and left to right covering the entire screen) with the flashlight technique in order to see any image on-screen.

We have a sharp aquos. We have audio, but no screen image and i can't firgure out how to restore the TV image

Is this through the tuner or input? If its through input check or switch out cables first. When you have sound if you can shine a flashlight into the screen and see movement or video, your backlight is out, which can be a invertor board or bad capacitors on the power supply board. Invertors have to be replaced, some power supplies can be repaired. A repair shop will be able to tell which it is.

Sound yes, but no picture on tv

If you have sound on the stations this is a problem in the display. Take bright flashlight and hold it against the screen. Look for an image around the edge of the flashlight. If you see an image then it's one of three problems;
1) The inverter board is bad.
2) The CCFT (cold cathode fluoresent light) are bad.
3) The power supply to the inverter board is bad.
Someone knowledgeable in electronics can replace the bad part(s).

Pioneer PRO-FHD1 Plasma Monitor Start-Up Problem. We bought this Panasonic plasma monitor 16 years ago and it has never been serviced, so all parts are original, and the unit has never malfunctioned -- until about a month ago. The system fails to power on. At first a month ago this happened rarely. We learned to unplug for a few minutes to drain the caps, then re-plug, and the monitor would start normally. Now, we plug-in, turn on the main power switch, and the red stand-by light illuminates. When we press the ON switch using the remote control or onboard switch, the blue Power light comes on for about 6 seconds as the screen goes to dark grey, then back to black, with a power board double relay click audible. Then there is another single relay click and the red Standby light flashes 3 times, then pauses about 3 seconds and repeats over and over. The screen stays black. Now, if we repeat the de-power/re-power process many times, the monitor eventually powers on, and functions normally -- until the system is turned off and cools down for a few minutes. If the monitor is shut-down and restarted while warm, it usually re-starts normally. All of the caps on the Power Supply Module look normal except one that was very slightly bulged, which I replaced, but I suspect that there is another component failure on that board. I have also physically plugged/unplugged all of the wire bundles to the Power Supply Module, and tightened the mounting screws. I've removed the board and closely examined it in the process of replacing the one suspect cap. The board is labeled as manufactured by SanKen, with a part number sticker showing: AXY1148BE0606008931. I took some advice, and used a hair dryer to heat the area of my supply board with the suspect cap, and the monitor started normally. I let it cool, and it failed again. I re-heated it and it returned to normal! Another heat/cool cycle confirmed that there are a few more bad caps that need to be replaced. I'll let you know...
