I would suspect leaky capacitors on the power supply board. Take off the back cover, and check the capacitors on the power supply board. If you find any that have bulging tops, they will need to be replaced with the same uF of capacitance, at least 105 degree C temperature rating, and with at least the same voltage rating.

First, I would try leaving the TV unplugged for an hour so the TV can discharge and reset itself.
If this doesn't work, it maybe something simple like a blown fuses inside the TV that needs replacing. Radio Shack or some electronic store will carry the fuses.
If the other two ideas doesn't solve it, we're talking about a power supply board related problem. I can actually look at your TV over the internet. But, the most common problem with flat panel TVs are the power supply board for the screen itself and the main power supply board for the rest of the TV. Commonly a bad capacitor or transformer will be on the board.
If you have some electronic experience and want to repair it yourself, you can sometimes find a Service Manual for your TV over the internet. Normally, costs less than $20. It will have diagrams, schematics, and part number list for the TV.

Hi.

If the TV keeps shutting down and goes in standby, then the TV is going on protect mode after detecting a malfuncion.
When this happensthe TV gets shut down to prevent further damage to internal components.

Before calling support ensure that you have followed the indications here Why my TV does not start up and remains in standby.
Troubleshooting basically consists in leaving the TV unplugged to drain power completely and discharge internal circuits. Instructions are for a DLP, but procedure is the same with any TV, even plasma TV.

The best way to contact an authorized technician is by ringing the number listed on the owners manual. Alternatively try Fixya directory here:Fixya directory- Consumer Products Repair

Try first the troubleshooting proposed in link above. If that does not work, ring customer service.

Regarding the rpair cost, this depends on the part that is defective. A common fault is the power supply, but this is not necessarily the problem.

If you are a repairer,testing willl start from PSU, following voltages on main board and testic diagnostic points listed on service manual. Here the service manual: philips slc4.3e - Service Manual

For parts try Partstore or ShopJimmy .

Regards.

Ginko.

Not turning on


It would help to know the brand and model of the camera. If all you want is to get the pictures off, you can pull the SD card or connect it. That should get the pictures off.

What happens when you press the power button? Does anything happen (lights go on, screen flickers, error message, ...). I assume you have tried putting new batteries in.

Why does my camera not capture any picture? Whichever mode I use, it does not capture any picture regardless of how many times I click the button.


Flash flicker is the camera trying to get enough light to focus, It occurs when you press the shutter release part of the way down.
Try the same thing outside, ensure you press the shutter real ease all the way down. If it still does not fire, switch the lens to manual focus (sliding switch on the side of the lens, move from A to M) If the camera shoot then, the camera is struggling to auto focus.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

No picture, no sound?!?!


This could be a number of things. Your lamp could be bad or it needs to be reseated to the ballast. The lamp is trying to light and it will make the ballast flicker (that is the clicking sound) or your ballast is bad and it needs replaced (it will flicker and click too). Or your color wheel is broken and it will make a clicking sound when turning. If the color wheel is not spinning or broken it will not light the lamp. No lamp no picture.
