Hi,



One of the many reasons could be the power supply

My Picture started to flicker - 64.jpg PROSCAN 40LD45Q LCD TV POWER SUPPLY AYL400201

these may look like these

sample image:

Options :

One may have to open up the TV and check:

( Before ordering )



for possible bad components

( and board confirmation If it is the same on the link )



like for visual, capacitors in orange circle



If there seems no bulge or swelling capacitor,

then Voltages should be measured ( yellow box )

How to use a multimeter

If the initial ( standby voltages like 5V ) are gone

then these board should be replaced or

properly checked.


Although there are still fuses on the power supply

Troubleshooting


These power supply have Transistors

and MOSFET

How to test MOSFET


There could be other causes but let us start from the

power supply first.

Sony KP-53HS10 Flicker, Crackling, Blue Shadow Problem


ok from what i see in this video, you have a bow at the top turning this flash. looks like you may have a weird shorting problem in your convergance ic's. try unplugging all your convergace yoke connectors and see if it stops. if so then you will need to replace all conv ic's. do not run set with conv unplugged for very long as it will cause resistors to heat up and possible burn them out.
30 secs to a minute max for testing. if you tv does not do this when you first turn it on, then wait for it to act up, then unplug conv plugs while set is on.

My 32inch lcd tv keeps flickering it started all the sudden


TRY THIS

    • 1 Turn the TV off with the front-mounted power button, not the remote. Unplug the TV's power cord from the wall outlet. Let an hour pass before plugging the cord back into the wall outlet. Turn the TV back on with the front-mounted power button and wait until it has fully restarted. Bring up a TV channel to see if the image being presented on the LCD screen is no longer flickering. A momentary power surge can cause the circuitry inside the LG-brand LCD TV to function erratically.
    • 2 Unplug the video cable from the video connection on the back or side panel of the LG TV. If more than one video cable is connected to the TV, disconnect all of them. Disconnect the other end of the video cable from the video source device that it's attached to -- a DVD or Blu-ray player, or a satellite receiver or cable box. Blow off the connections on the video source device and on the back or side panel of the TV with bursts of compressed air. Reinsert one end of the video cable into the video source device and the other end into the video input that it was connected to. Turn the TV back on with is remote to see if the picture is now free of flickering. A loose or partially connected video cable can cause the LCD TV's screen to flicker when presenting an image.
    • 3 Turn the TV off and unplug its power cord from the wall outlet. Place a power conditioner next to the wall outlet. Plug the power conditioner's power cord into the wall outlet. Plug the TV's power cord into one of the AC sockets on the power conditioner. Turn the power conditioner on. Turn the TV on to see if the picture is now free of flickering. The RF signals in the electric line that the LG TV is drawing power from can cause flicking through interference patterns being generated.

My LG Lcd tv takes a minute or so to turn on then sometimes the picture flickers and goes out. The tv is on but no picture or sound. When I try to use the menu button on the tv it doesn't work. Whe


The fact that you have no menu or onscreen display, leads me to believe that it is the main logic board. Either the processor ic or the voltages going to the main board are missing. Check to see if the main board is getting 5v and 3.3v to determine if it is your power supply not supplying the voltages or your main board.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Have a daenyx dv-833 dvd player


Good Morning,

Your connection is very easy so we should not have a problem isolating the problem.
We just have to go slow step by step.

First lets just check the Yellow cable just to be on the safe to side sure it is connected properly on the back of the DVD player and on the Televison.

Second, If the connectionn is secured. Turn the DVD player on, make sure you do not have a disc in the tray then turn the DVD player off.

Make sure the battery on the remote control is a fresh new battery (process of eliminattion).
Hold the remote control in front of the DVD front panel.
Turn the DVD player on with the remote control. Look on the front panel of the DVD player, it should read no disc. Press the Pro.Scan button "once". (Have you notice a flickering on the Television Screen).

If no flickering on the TV screen, press the Pro.Scan button again, ( this will be the second time). Have you notice the flickering?

If not, press the Pro.Scan button again ( third time). Have you notice a flickering on the TV screen?

Did you not notice on the LED of the DVD player if it read anything when you pressed the Pro.Scan button?
Try the above procedure again if your picture did not resume. If the picture resume in black and white, do not press the Pro.Scan button anymore.

Let me know the outcome up to this point.

Thanks,
Mike H.
