The power on light on my Sony KDS-55A2000 TV just blinks red

Customer Question

The power on light on my Sony KDS-55A2000 TV just blinks red 4 times then starts the red blink again in a few seconds. It had just quit working on me suddenly and from experience I thought the projection bulb had blown. I had 2 new ones here and changed the bulb. Per instructions in my manual, I took out the bulb and carefully reinstalled it. I even tried the other new bulb I had. But it still blinks red 4 times over and over. What do I need to do to try and revive my TV?

Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems.

A 4 blink code on this set is a Fan Error per the service manual, and this means one of the three fans inside of the set has stopped spinning (due to dust/debris, failed bearings, etc.).

If you're looking to repair this yourself, you will need to be comfortable disassembling the TV, then accessing and cleaning, lubricating the 3 fans in the set (it's generally the rear exhaust fan however). Is this something you're looking to do yourself?

If so, let me now and I will pull up the service manual for you.

Alternatively, if this is not something you're comfortable with- then a shop will typically charge between $150-$250 parts and labor to clean/replace the fan(s) as necessary. Keep in mind either of the three fans will trigger a 4 blink red code on the set. It doesn't point to a specific fan, it simply indicates "Fan Failure".
