SOURCE: sony tv kv-36fs120 will not turn on

Use a hair dryer on the back right side of unit. Humidity sensor may be causing the unit to stay off. The hair dryer may also remove dust causing a false humidity detection

SOURCE: Sony KV-35S66

I have had a similar problem for three years with my KV-35S66 (purchased 12/99). With my TV, I get no picture and the red LED flashes, but it doesn't cut out -- it will keep on blinking. Sound comes through fine.

My fix is to put a space heater right in front of the TV for an hour or two, then turn the TV on (or off and then on again).

It appears to be something in the electronics that needs to be warm to work properly (loose connection that expands when heated?). Once the TV is on , the TV stays warm enough to keep the picture (i.e., you can remove the space heater). I just leave the TV on constantly (it is in the basement and doesn't bother me, and my satellite displays a screen saver). TV is otherwise fine and the electric cost is much less than buying a new TV.

You could turn off and then heat up when needed, I suppose, but that takes some planning ahead.

SOURCE: TV does not turn on

On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

Why is red and green light flashing in air condition

If it's an air conditioner it could mean changing or cleaning of your filter screen. On an AC unit you can have one of four typical lights..
1.. No light-no issues because it's off.
2-4 lights depends on if one solid or blinking light (either red or green) or in other senereo two staying on our simultaneously blinking. Can also alternate blinks. These are codes for HVAC technician. Sometimes if there was a surge in power you can trouble shoot only one situation-try unplugging the unit and plugging it in upside down if possible (some models allow for it) if not... Leave it unplugged for a good 5 minutes and replug it in and see if you get the lights. If not it should be good. If you do, it's time to call a technician. Hope your issue gets fixed. Be blessed...

LG 65UH5500 TV just died while watching it. Screen gone black, no sound.

Those 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.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Standby light flashes 4 times

One option to try is to try to factory reset the tv, to do this turn the tv on hold the Down Arrow on the remote and while doing this press the power button then release the down arrow button.
