This is a fan issue, most likely the large fan in the rear, lower left (from the back)...

Here's the fix, I promise, it's EASY........


Ok, I think I have the answer for the BIG FAN failure. I recently did a similar fix on the spindle of an xbox 360 and it is identicle. Ok, this is an EXTREMELY EASY FIX...

Open the back of the tv, locate the large fan (on the lower left on the back of the set.) unscrew the screen and remove the fan.

Once the fan is removed, you will see the side with the model number and the other side is totally open.

On the open side, pull...

The fan will come off, into your hand, it is only held by magnets...

You will notice a spindle on the fan and the other side has the magnets and the hole where the spindle came from (this is the fan motor).

Clean both the spindle and the hole (motor) with a q-tip. The hole is smaller than the q-tip, but do the best you can to remove the old lubricant.

Get a bit of WD40 and lubricate the spindle and spray a touch in the hole.

Put them together, reconnect your fan, test it on startup and thank me...lol...

HOPE THIS HELPS!!!! IT WORKS, TRUST ME...

Just replaced lamp/housing and now tv turns off after 2 minutes of being on. Green light flashes continually(about 30 sec.) then tv turns back on and the cycle continues. The tv is a sony bravia...


Strange situation, have you tried unplugging it for a few minutes and letting the TV cool. I have a older 2006 Sony SXRD rear projection and it takes forever to turn back on if you shut it off then turn it back on. Check this link and maybe its giving you a blinking code. Try counting the number of blinks. Hope this helps.

Hi,
4 times red light blinking indicates problem with exhaust fan that is not running and tv shuts down instantly due to protection mode activation.
Please check exhaust fan and make sure its connector is plugged in and fan runs freely.
Thanks.

Hi! GREAT site! We have a Sony SXRD KDS-R60XBR1 Projection TV and it stopped working last night... We are getting FIVE red blinks! What does that mean? Fans, bulbs.... ??? Thank you in advance for any...


5 blinks if for the ballast that powers the light. You can try changing the bulb first, if that doesn't fix it then I believ it will be your ballast. If you haven't changed the bulb before It could probably use one anyway, and you could keep the old for a spare.
Here are some more from sony on this.
According to Sony:

Red LED Flashing four(4) times
o Fan not plugged in
o Foreign object hitting blades
o CN2301 on ASU board not seated or connected
o ASU shield touching S1 board

Red LED Flashing five(5) times
o Interconnect harness from Lamp driver 5-pin to ASU 9-pin board not connected
o Lamp driver failure
o Bent pin on Lamp driver 5-pin connector
o DSU to C board harness not locked
o CN6501 on G board not seated or connected
o Lamp failure

I have the 50" SXRD TV and have expereienced many of the same problems as other owners. Sony replaced the optical block at no charge after the screen yellowing effect took place. Recently, I have the TV shut down with the flashing red light blinking in sequences of 4. After unplugging the TV for a few minutes, replugging it, and turning it back on, it worked again. However, this was not a pemanent solution as the problem returned. After reading several posts here, I turned the TV to look into the fans and voila, the one on the left was not spinning.

I took the back off of the TV (9 screws) and took apart the fan housing to vacuum everything. In addition, I vacummed everything else I could see. After putting it back together, the problem was solved. Save yourself a repair call. Get out a phillips screwdriver and a vacuum cleaner. Thanks to the posters on this site!!
