HI, Our Sony t.v. was working perfectly and then all of a sudden I went to turn it on and the screen was black. The standby light flashes 4 times but that is all. No sound, no picture, nothing.

Try unpluging from the wall and theplug back in and try turning back on to reset. Sometimes holding the power button in while pluging back in will reset it, every brand is different for the hard reset.
try this:
it works for slimline PS2. might work for PS3.
1) turn off PS3
2) unplug PS3 and wait a minute or two before plugging back in.
3) turn on PS3
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.
Be sure its blinking 5 times, count after it cycles the first time through the red lights. If it is fact 5 times, that is a lamp driver error.More likely it cycled 4 times, which is common on this model, if that's the case, then it's the fan. Most likely the large one in the rear...It's an easy fix, just pull the back off and replace the part.
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.
what model of Sony is it? On many of the Sony projectors, a 3 flash error code indicates the lamp is not properly seated/installed or the lamp door is not closed properly
The Sony error codes go up to 7, so when the standby light flashes 11 times it usually means that one of the clock or data lines deep inside the set is shorted to ground. This is not fixable from the front or through the remote, so the set should be serviced by a qualified tech familiar with Sony sets.
