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

Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} My Sony KDF-50WE655 will not power up. Flashes picture/sound for 1 maybe 2 seconds then shuts down and red standby light flashes 4 times over and over. Bulb appears to be OK I have checked cover is secure and it lights for the few seconds. Tried unplugging for a length of time and restarting - didn't help. Sony says get a service tech. Any help would be greatly appreciated.

    Thanks. I'll try checking fans but since it never actually fires up for more than a couple of seconds, will it have time to over heat?

  • chauncymcnab Jan 27, 2009

    A thousand thanks!

    One fan was not working. A small piece of plastic had wedged in it, probably from transportation. I freed it and it fired up right away.

    This of course begs the question; where did the plastic come from? AAARRGGHHH!!!

    Thank you so much!

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?

    Bad heat sensor can be cause of that problem as system control get signal of over heat just after powering up TV.

We Have a Sony KDF-50WE655, we've replaced the lamp and housing and we still have no picture or sound. Can you help?


Make sure that lamp cover is fixed back on its position securely after lamp replacement, turn On tv to check.
If still no picture or sound then check power/standby light is blinking?
If yes, count it how many times it blinks after 3 seconds long pause and let me know to diagnose possible cause of problem.
Thanks.

My sony 50" wega just quit. No picture , no sound , no nothing ?


Hi,
If you see standby red light blinking on Tv front with 3 seconds interval then count its blinks from pause to pause and let me know, its an error code.
And if TV does not even show standby light then check fuse in power supply that would be blew off for some reason, replace it.
Still problem? let me know with exact model number of your Sony TV.
Thanks.

Its possible that one of your fans has failed, and or it could be the lamp itself. Sony television will not power on if a fan is faulty. Open the back of unit and look at all fans to make sure they are running, if so then replace your lamp.
