When I push the power button, the red light flashes and no picture shows up. it just clicks right back off? do you know what causes this?

I do not know allot about the s5090, but I can give you general information based on how most Nikon pocket cameras are designed to work. If the Nikon is set to one of the automatic modes it is designed to prevent you from taking a picture if it senses that there is insufficient light to get a properly exposed picture. The camera may be telling you to rase the flash because it needs more light. Also, somewhere on your camera there is probably a menu that allows you to choose the flash mode. It may be in your regular menus or, if your camera has a round left-righ-up-down switch on the back, you can select the flash mode by pushing up and then using the right-left keys to choose the flash mode. The mode you select is locked in when you push the button in the center. In general, the modes are automatic (the camera decides when flash is needed), red eye reduction (the flash activates twice; once to cause your subjects eye's iris to close and the second to take the picture), flash always (flashes regardless of the ambient light) and flash off.

Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

To turn off the service light that is flashing red on your V4 BHM ceiling lift, you have to proceed this way:
1- Power off the lift with the red cord
2- On the hand controller, push on the PROG + RETURN button at the same time and maintaint it
3- Power on the lift
4- Keep pushing on both buttons, and push in order: UP, DOWN, LEFT, RIGHT.
5-The green light will flash and the buzzer will beep 5 times
6- Release all buttons on the hand controller.
7-Push on the UP button many times, till your hear 4 beeps
8-Push the PROG button once.
9-Push on the LEFT button many times, till your hear 3 beeps
10- Push the PROG button once.
11-Power off the lift with the red cord, then back on.
The service light should be off.

hi
you have a shut down problem cause by a defective power suply that probably goes to high and activate a x ray or fail safe potection

This is very common in sharp tvs.U turn it on.U get power on light stable right?U hear a click,one or twice,sometime tv is good right?Sometime POWER light and OPC light flashes?Push the power button on/off couples times will work, picture will come on.If keep trying off/on couples time after POWER and OPC flashes,don't ever stop and never get backlight and picture.Ur Video backlight board is dead must replaced.

Replaced the sc board and tv works fine again.

The SONY Owner's Manual for the KDS55A2000 does not state what the 4 times blinking Power LED means.

However, my Sony Extended Care Service support insists that the projection lamp is the cause for the 4X blinking LED
Power light.
I do not agree but am forced to buy a replacement lamp (not cheap) to prove that the problem is probably the fan, as the TV Technician states elsewhere in these FixYa support questions and answer

A fuse is not your problem. this TV has a safty feture that when it senses a problem it cuts the power to prevent any fouther damage, when you un plug it the TV resets and it will turn on agian. I have the same TV Check the CRT light guns there are 3 of them. If one goes bad it will cause your problem.

This showing the tv have power. Maybe when you pushed the power button it clicks and shuts down then show the red light bliking showing one code. Some shurt on horizontal board or loose some voltage from power supply. This is not easy if you don't have experience with electronic. I'm sorry still tring

I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.
