Picture and sound flashes on and off

The picture flashes on and off there seems to be no rhyme, reason or timing to pin down. Sometimes the "flash" is longer than others sometimes there are several flashes in a quick period.

    I have also noticed that after the longer "flashes" the HDMI box in the upper left corner appears.

We recommend you test your HDMI device on a different HDMI input on the TV. If the problem persists then we recommend you replace your cable or satellite box.

SOURCE: Pana TH-52PWD8UK. No picture, flashing red LED on front panel

Humidity is an enemy to electronics Solder and coductive componets corrode quickly. Since you no longer have power I would just start trouble shooting at the power supply. AC in , yes look for fuse. There is a constant +5 volt from the power supply that goes to the main board. This voltage is present when set is plugged in . This maintains the micro at a standby condition. When turned on a turn on voltage is sent to the power board to turn on power supply. There are conditions that must be met by the micro before turn on is allowed. Lamp door switch is on. If you cant get this constant 5 volts even if you disconnect it from the main board then replace the power board. Hope this helps.

SOURCE: panasonic th-50pz800u shuts down and i can not turn back on, red light flashing 2 times, sometimes 10 times

Good day!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Canon 430ex ii seems to flicker rapidly sometimes before taking pictures

Yes it is. The system is simply measuring the flash to meter the exposure.

TV turns on, only voice,no picture,red light will flash, no click

You may have to resolder your vertical IC. This seems to be a common occurence for many Sony TVs. This is my first diagnosis when I get one of these in. But, yes there could be a bad ground almost anywhere. You will need to pull the board out and resolder any IC mounted on heatsinks and any large power resistor and resolder the pins connecting the flyback transformer to the board. This tip is always the first place to look for in repair. Good Luck and be mighty careful. Thanks for asking!

My Pioneer DEH-P860MP has had an issue to where it will power-up and down on it's own. Sometimes power will flash, which I can tell as the display may illuminate for a brief moment and/or the faceplate...

you may have a bad flexible cable that goes from the face to the main pc board. there are two cables, one that goes to the upper face and another that goes to the lower fac. typically the one that goes bad is the lower.

Have Canon EOS Rebel Xsi Digital. Burning smell and flash busy.

Are you trying to use the flash when you are having the problem? Were you taking a lot of pictures with flash when the problem started? Rapid pictures with flash can melt the flash and capacitors in the camera. Also, a single drop of water rolling around inside the camera in the right place can do things like that. You can try taking pictures in bright sunlight so the camera will not try to use the flash and see if it will work normally, If it does than something is probably fried in the flash system. Bad thing is that if you smelled smoke something is most likely already fried and will have to be repaired by canon. Canons quality has been going down hill for several years now and they have a lot of quality problems. If the camera has been used very little, has never been abused, dropped or wet and not far out of warranty, try using google to see if this is a common problem and call canon and try to get them to repair it for free. If all else fails threaten to replace it with a Nikon assume pay to have barely used camera fixed.

Error "Err05" keeps initiating preventing flash operating

There are two versions of this problem: 1. The flash does not pop-up. 2. The flash does pop-up.

Here’s the fix to the err05 msg when the flash does pop-up. This will work on the XTi and perhaps on similar Canon cameras:

The pop-up flash has two legs. Look at the pivot point of the right leg (”right” when looking into the lens). Just in front of the pivot is a very small spring-load pin on the “roof” of the camera body.
This pin is the sensor that tells the camera the state of the flash. The pin is pushed down when the pop-up flash is closed and is suppose to quickly spring up when the flash is opened. Problem is, the pin sometimes gets dirty and drags. When it is slow to spring up … you get the err05 message.

Fix: Take a small jeweler’s screwdriver and dip the tip in isopropyl alcohol. (Don’t use any other solvent unless it’s designed for cleaning electronic parts!) Then touch the screwdriver tip to the pin. Do this several times until the pin area is nicely wet. Then push the pin up and down until it is able to spring up quickly.

Vibration alert - blurry pictures


The vibration alert flashes when the lighting conditions are poor and the flash is turned off. You can still take pictures in this mode and if teh camera is well stable, the pictures will be sharp. In low light conditions like indoors, turn on the flash or set the camera to Auto mode.

You need to let the autofocus time to focus. Press and HOLD the shutter button HALF WAY and wait for the white rectangle on the LCD display to turn green. Then press the button all the way down to take the picture.
