Tv went black and no sound standby light falsh twice and paused and flashed twice again

Does the screen flash on briefly then go black when first switched on? See my posts in march for my answer to this fault.I traced the same fault on my own tv down to a faulty led in the backlight strip. Also my tv did the same thing,standby light flashed twice and then went out.Hope this helps

Either your power supply is bad and needs replaced, or their is other circuitry issues. Bets to have a trained technician look at this and give you a quote for repair, it might be cheaper in the long run to replace the set.

This is probably an error code .this is to help service personnel to find the fault.

this specific type of TVs flash their standby light if the onboard testing system sniffed out a problem

so, as if your TV is trying to tell you "i have a problem and i need to be serviced"

i hope it goes well for you
:D

This blinking is a diagnostic code. Please update this with the model number. These sets contain circuitry that will shut the set down and display a code like this when a problem is detected. With the model number, I can look up the problem and provide potential repair suggestions.

My Sony trinitron has the stero lite on steady and standby lite flashes four times then pauses and repeats. Can you tell me the circuit/condition causing the set to not turn on.

Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

I've got exactly the same problem. Initially, I saw it flashing twice, pause, twice, pause, twice... I pulled the plug when it failed to respond at all. And then when I plugged it back in, it went into the continuous flashing mode. Halp!

The red light should be blinking a code. For example it will blink 4 times pause then 4 times pause or 5times pause 5 times pause, whatever the error might be. Let me know what it is and then we can help more.
