GreetingsCustomer can you list the model number of your Sony Wega? It would also help to know which light is blinking and the color.

Hi - KF 42WE610 is the model number - also the blinking light is the power/standby - I was watching tv the other night and the tv just went out and I heard the lamp blowout. I have replaced the lamp (I've done this before) and attempted to turn the tv back on. The Power/Standby light turns green as if ready to turn on then turns red, stops and then blinks three times intermittently until powering down and remaining red after a few minutes. I've read that the 3 blink problem alerts to a specific problem (unlike 4 or 5 blinks, etc.) So I am trying to find out how to fix it. Thanks
Expert:  Dan - Master Tech replied 5 years ago.
Sorry I missed you, I was just getting ready to turn in for the night and saw your reply. You are indeed correct, the three blinks of the Power/Standby light do indicate a particular problem. In fact, it is an indication of what may be considered the most serious problem of all.
Did you close the door? Sorry, it's late and I couldn't resist. The three blink indicator for this set shows a fault in the trip switch for the lamp door.
In the event that there is more than one malfunction, the item which first occurred blinks. If the malfunctions occurred simultaneously, the item with the lower blink count blinks first.
So, here's hoping for the simple solution. Let me know.
Dan

P.S. Just in case it turns out to be something more, I have the 156-page service manual available if you need it.
Customer: replied 5 years ago.
Sorry for the delay. I'm not sure I understand what you're instructing me to do. Check the lamp door? For what exactly?
Expert:  Dan - Master Tech replied 5 years ago.
That's OK. The lamp door has a small switch that will disable the TV if it is activated. If that switch is not working and is stuck, or if the door is not closed properly, it can cause your problem.

Customer: replied 5 years ago.
when you say "the lamp door" what is that exactly?
Expert:  Dan - Master Tech replied 5 years ago.
Sorry, I should have used the proper terminology for this particular TV. I should have said lamp cover instead. If the cover is not secure, the Power/Standby lamp will blink 3 times.
Dan
Customer: replied 5 years ago.
It looks like the lamp door is melted, as well as some of the plastic casing around the lamp jack. I think this baby's a goner....
Expert:  Dan - Master Tech replied 5 years ago.
Wow, that would certainly give you the three-blink problem. This happens as a result of the fan not working properly to cool it down. As I mentioned earlier, I have the full Service Manual for this TV if you can use it. The problem you have is repairable depending on what you care to do.
Dan
Update:
Since this is a fairly common Sony problem, they have issued several service bulletins on it for various models. In some cases, Sony has offered to repair the TV or offer a credit on another one. I will check to see the status for your TV.
