Blinking red light in front of tv (lamp) and noise coming from tv as well.

If the red light is blinking in front that sasy lamp. Your lamp needs to be replaced. They cost about $100.00 at your TV Fix It shop. Very easy to replace yourself

Sounds like it just needs a new lamp.
The way to tell is the lights in front:
green blinking as TV reboots = bad lamp
red three blinks = door switch
red four blinks = bad fan
6 or 9 blinks = bad thermal fuse

One question, why you decided to replace lamp in tv? Did tv showed red lamp light blinking?
Suggestion, make sure lamp cover has been placed back in its position after lamp replacement, lamp cover is first thing that you removed from tv cabinet to take out lamp.

Hi,
Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?
Thanks.

Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

You are hearing the spark gap mounted on the lamp ballast board. If you can hear that sound, that means everything in the lamp driver circuit is working except the lamp!

Get a new lamp.

Hello,

The TV should "blink" a number of times after it fails to start up (the red light blinks a certain number, pauses, blinks a certain number, pauses, etc.). This tell what is wrong with the TV. If the LAMP light is what is blinking, then the lamp needs to be replaced.

Most of the problems with this television are related to the lamp or lamp chamber. If the Television lamp is burned out or worn, or the lamp will not start, then it will not try to come on. There are circumstances where the LAMP light on the front of the TV will not come on, even though the lamp is out. I would try replacing the lamp (which is meant to be user-replaceable). The popping noise you heard could have been the lamp going out.

The lamp chamber door also activates a switch that tells the TV that the door is in place. This switch will sometimes go bad, showing a relatively small amount of resistance, but enough to fool the TV into thinking that the door has not been replaced, causing the TV to shutdown. Make sure that the lamp door is properly replaced if you do remove it. It is no longer available from Sony (too many warped doors from heat damage).

Lamp part number is available in the user manual, as well as instruction on changing it.

Hope this helps you...

Hey there,
I've had my Sony KF-50WE610 for approx. 4years now and have just experienced the prob you described (though I didn't think to count the number of red blinks). I called Sony TV technical support (888-772-7669, #3 for TV/digital cameras, #1 for TV, then #1 again I think). They said that if the power/standby light blinks 5x, that means there's something wrong with the lamp driver and service will be required. Needless to say, I better go home and count my red blinks! Good luck, I hope this helps a bit. Have a happy and safe holiday!

Your service manual on page 82 steps you through decoding the blinking
1) there are two lights on the front near the reciever of the remote signals (Temp indicator and Lamp Indicator)
2) If the Temp indicator is on then they recommend you contact a service center
3) If the Lamp indicator is on and the power light stays on (no blinking) then you need to replace the lamp. Otherwise it says to contact the service center.
4) Counting blinks with the lamp indicator (1 every 5sec - lamp will not light or is abnormal, 2 every 5sec - lamp voltage is abnormal, 3 every 5sec - lamp temp is too high, 4 every 5sec - other error)

You really should give make & model number when posting, it helps us immensely, your lamp and possibly the ballast is bad, start with a new lamp first, odds are very good that it will fix your problem, can`t help more without manufacturer and model number, good luck, ps, order the original lamp, generics are junk and a waste of your money.
