It looks like your power module is on the blink. Do you get any picture?

Re: Bravia KDL46EX720. Red LED blinks 4 times and TV wont turn on. What is the problem?

Do a Power Reset.

1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.

If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

The 5 blinks is indicating the lamp ballast needs replacement your model uses the Sony lamp Ballast 147401211 for sony models KDF42E2000, KDS-50A2000, KDS-50A2010, KDS-55A200, KDS-60A2000, KDS-60A2010, & KDS-60XBR2 amd LDS-R60XBR2
Which is available at the bottom of the page at the following link. The ballast comes with installation instructions,

Hi,
Red led blinks 4 times is an error code that shows that fan is not running in tv, check fans connections and make sure all are plugged properly.
Thanks.

If its Sony KDF-42WE655 TV that goes to standby and LED blinks 3 times then check Lamp Door that seems not fixed properly.
That happens when lamp replaced in TV.
If its different model number TV, let me know exact model number.

Sony TVs generate an error code. The front panel LED (red) will flash anywhere from one to eight times which can isolate the problem circuit. It is not always accurate.

If you have a test meter which can read DC voltages and resistance in ohms, you can locate the problem area. If you lack the expertice to do so, contact a sony authorized servicer. If you have the ability, start by checking fuses on the "G" board ( power supply board) and the "D" board or deflection board.

A major problem area in this TV is the convergence circuit. There are six fuses around the convergence output ICs on the "D" board.

If any are open, replaces the output ICs.

Sony TV;s will give a service code, count the blinks, eg; 2-6, light will blink X amount of times, hesitate & blink again so many times. Count and report back but, I would recomend to unplug the TV's power cord, to reset the TV's system. Unplug for at least 3 minutes. I hope this was helpful.

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
