No power black screen standby light flashes - Sony KV-27S42 27" TV

Redcoat Jan 13, 2008

The television was fine then it turned off and the standby light is flashing and the timer light is on. I've unplugged it and turned it off and on, but to no avail.
I was cleaning around the television at the time and might have bumped a button on the front by accident. I'm not sure.

Hi, Most new Sony TVs have a built in self-diagnostic feature. One of the led lights would be blinking. The number of blinks (on/off) is indicative of a code. The code represents a system fault. For example on some versions, 3 blinks indicate diagnostic mode where the builtin protection has kicked in (very likely a powersupply problem). How many blinks is the standby light doing? Due to the technical requirements to repair this TV, you would probably require the services of a qualified TV professional very familiar with Sony models. You can try a hard reset by unplugging the unit off from the mains for a couple of hours. If a no by then, we're back to the tech. Good luck and kind regards.

Hello!!! My samsung TV is making a clicking sound, and red light flashes, I don't know if the TV is actually on or if it's just appears to be a black screen.

It is most likely that your power supply PCB is faulty. Some have had luck with the following procedure to correct it, so you might try this:

Unplug the TV for 30 seconds, and then plug it into a working outlet.

If the standby light comes on (and doesn't flash or blink), your TV is receiving power and will probably turn on now just fine. ...
If the standby light comes on but flashes or blinks, or if the standby light still doesn't come on, service is required.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
