SOURCE: No picture, but power is on...

Hi I have sort of the same problem with my sharp TV. It turns off when I play on my xbox elite. Sharp have been out 3 time and replaced a board in the back but insist there in no compatibility problem. I suggest you call sharp and maybe they will admit there is a problem with the TV they make.

SOURCE: When TV is turned on,

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.

4 times blinking means Fan stopped, power is not supplied on Fan 1, Fan 2 Fan 3 and at Fan 4. Or Fan connector is not attached securely. Cleaning these fans by using a vacuum cleaner can also solve your problem. Sometimes these fans are clogged by dust.

Projector screen turns off after 10-20 seconds


Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

Sony LCD television will not power on.


I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.

How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
