I had recently had a problem with the Video block or Light Engine as some call it. The TV had blue blotches and streaks in the lower right side of the screen. I sent the light Engine in to TSM INC. in Evansville, IN and they rebuilt it for $300.00. I just got it back yesterday and when I reassembled it I forgot to plug in a connector thus the failure code of 4 red light flashes. I took it back apart and discovered my mistake, corrected it, reassembled it and the TV works perfectly. If you need any help with this process, let me know.

Wont turn on. Green light comes on for a few seconds, andthen goes back o0ff.


Hi if its a Lcd or Dlp rptv most likely its time to replace the lamp if tv is between 2-4 yrs.If you hear clicking it could be the ballast which is the board that powers the lamp.Make sure fans are running ok ,dust them out if they are dirty.God bless you!

Power light flashed red 4 times then repeats no pic,new bulb/fan!


Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

Sony KDF-50WE655 will not power up. Red blight blinks 4 times


4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

When first attempting to turn on my 60" XBR Blinks green on power indicator, Tv turns on a split second and light turns to red and blinks 4 times. Please help me understand what is happening.


Thanks for your support with my situation. I read many people's complaining about having a red light blinking 4 times in the Pwr. display. It was recommended I blow out the fan for the bulb. I did just that and it did solve the problem, at least for now.
The fan kicked on which allowed the Tv to power up.
I am guessing this is a common issue and made sense that the fan was stuck with dust.

I can't thank your site enough for this valuable information. Spending 4k and already having one unit replaced with what was a factory inherent problem and then going down so quickly was very upsetting.

I am hopeful it will work for now on.

ON/OFF button (red - off and on - green) flashing all the time


it is important to count the number of red flashes, if it is 5 then the lamp ballast board has failed, (part #1-468-798-14) if it is 4 then the optical block fan (# 178706511) is probably to blame, if it is 6 then the thermal fuse has gone bad..(# a1137954a)

4 red blinks indicates a fan error. usually blowing duster inside the fan blades will cure this. there are 4 fans inside this tv. looking from the back of the tv, the large fan on the left side is usually the culprit...good luck to ya
