EZ FIX 4 kdsr50xbr1 4 BLINKING LIGHTS FAN READ!!!

post #1 of 87
Thread Starter 
Is your Sony shutting itself off and blinking the red led 4 times? Guess what? It's the fan...

Don't waste your money buying a new one, I have the absolute easy fix:

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 identical. 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 start up and thank me...lol...

HOPE THIS HELPS!!!!

IT WORKS, TRUST ME...

Followed FIXRUPPR direction, cleaned the fan but didn't apply WD40. Put them back together and voila!, TV works again.

I know this is an old thread, but many of us with these TVs are really starting to run into these problems at this point in their lifecycle (not to mention the assortment of other problems they have!)

I wanted to add that this worked for me as well I used PB blaster instead of WD-40. To be safe, I just sprayed a tiny amount on the spindle and wiped it with a clean paper towel. I didn't want to risk putting any in the hole for fear that it could ruin it. I don't know how much longer mine will last, but I was at least able to put a movie on while having some family visit. Thanks again!

FIXRUPPR - you sir, are a genius!

Did exactly as you said and our TV is back in action.

Thank You!!

Tried cleaning the fan as sugested and I have to say thank you . TV is working perfect . The procedure was simple and did not consume a lot of time . Beats paying 150.00 just to have the service guy to come out . If you can turn a screwdriver anyone can do it !

WOW!!! What a coincidence that every person in this thread is a newbie.....I wonder if FIXRUPPR is going into business for himself?
post #7 of 87
Wow. We just saved 150 bucks. I'm a 44-year-old female with no tv-repair experience and this was easy and it did the trick. My eight-, seven-, and three-year-olds thank you! I'm sure my hubby will too when he gets home. Thanks again.

Another "newbie".....

I found some other threads and went a got a replacement. $28 sure beats a $99 visit (or two) and taking time off work. I can't seem to pull apart the Airflex SFF21C from my early model KDS-R50XBR1. Search for part 8-835-860-31.

I got mine from www(dot)encompassparts(dot)com, if you are in Atlanta you can even pick it up from their Lawrenceville Distribution center - just beware the 4pm Friday traffic!

Just wanted to say thanks. This worked like a gem. About a 15 minute fix and saved us 150 service call. Thanks again - soooooooo much appreciated.
post #11 of 87
This is a joke right?
post #12 of 87
Yes, it must be a joke. I just posted this on the owner's thread but want to make sure anyone else who reads it doesn't 'try this at home'.

I had four blinking red lights just as described in the original post. I also confirmed that it was the large fan that cools the bulb which was my problem.

However, I tried to pull the fan blade off of the fan to lubricate the shaft and was not able to. I did get a new fan and that was the problem. After confirming the new fan was working ok, I went and pulled a bit harder on the fan blade and it simply broke off at the plastic hub where it attaches to the shaft.

I'd like to give the original poster the benefit of the doubt and think there might be different fan models, some of which may have a detachable fan blade. However, I'm not so sure...that definitely was not my experience.

Thank you so much!!! You are the man! Cleaned the post and whala, it works.
This fix is not a joke, it actually works, finally a suggestion that does what it claims.

You ROCK! Fix worked great!

"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..."

It took some pressure to get my fan-blade assembly from the fan case. Make sure to use the screwdriver close to the hub and do not try to pry off by the blades.

The world should be filled with more people like you. Wow that was the easiest straight to the point fix-it everrrrrr!!!!!! Worked like magic!!!!
post #16 of 87
Probably setting up to go into business and use this post as a way to show his/her prospective customers how good he is. Who would really bother to look that everyone who said it worked is a newbie and has never returned to post anything else. This thread should be deleted!
post #17 of 87
This thread is valid. My KDS-R50XBR1 wouldn't turn on today. Just the red light blinking 4 times. I did a google search, ended up here and cleaned the fan as stated. I was skeptical, but the TV fired right up. A lot of others have probably found this thread and fixed their sets. They probably registered just to thank the poster.

I am extremely happy that I found this thread.

Huge thanks to FIXRUPPR!

There is another fan deeper in the chassis. It is "squirrel cage" type and is located just above the lamp. More than likely, there is also a problem there. The big pancake fan may not be the whole problem.
post #19 of 87
A maybe stoopid question........ does this work on a 60 inch XBR1 as well?
post #20 of 87
I cleaned the fan with compressed air without taking it apart and it worked fine for a couple of weeks. Today I got the shutoff/4 red blinks again - the fan doesn't turn when I turn it on. I sprayed it with air again (forcing the fan to spin a bit) and now it works again, but I went to SearsPartsDirect(dot)com and ordered a new fan today for $28 plus shipping. I thought about trying to lube it as recommended here but seems like a stop-gap for a dying part.

I had to call them because the large fan (part #51 on the kds-r50xbr1 light engine #1 diagram) wasn't listed as an available part on the website, but it is in stock. Watch out for accidentally ordering the small fan located on the right side (from the back), part #57, by mistake. You want the large fan on the left side that cools the projection light. I also recommend keeping an extra projection light (very easy to replace) as a spare since they have a life of about 1000 hours or so. If the screen goes out with a loud "pop", your light has died.

My wife thinks I'm a genius - in the last week I fixed the dishwasher, the garage door opener, the coffee maker and now the TV, not bad for a guy that can hardly drive a nail.
post #21 of 87
Thank you so much. We just did it and it worked. We did not lubricate it but it seems to be ok. We were on the phone with Sony and they never even mentioned that it could be the fan. Thanks again for your post.
post #22 of 87
Thanks so much for your post. I had the red blinking lights on the front led on my Sony SXRD KDS-R50XBR1 and replaced by projection lamp (1st time after 6 years) with an actual Sony replacement part (stay away from OEM lamps).

After powering up the TV, the red lights were still flashing.

As suggested I took the back off the TV to expose the large fan on the left, removed the two screws, removed the propeller (held by a magnet) , cleaned the casing, applied oil to the spindle with a cloth which cleaned and lubricated the spindle, replaced the fan and cover, powered on the TV and it WORKED just like the day I purchased it.!

I do not know how much longer the fan life is and ordered a replacement fan just in case.

Thanks very much for the very informative posting.

Note: I purchased my Sony replacement lamp - original equipment from B&H, ordered Wednesday night, arrived Friday morning.
post #23 of 87
It worked for me too, the fan spun free without lubeing but there was dust everywhere, I sprayed the whole back of tv with air compessor and put it back together, watching tv now. The reason there are so many single posts is because this forum comes up first when you google sony kds..... red light blinks, all these people fixed there tv and have no other reason to post on this site except to say thanks, so thanks

If I read this last week - I would have avoided taking the entire set apart to clean all four fans. But on second thought - they all were caked with dust. That optical blocker fan is insanely hidden. But its better than running out to buy a Samsung for now. Never will I buy another Sony!

I bought mine from Amazon and it came the next day. Realized the fan was the issue and sent it back. Cost me $6.00 for return shipping.

This worked so well!!!! $15 part......TV works perfectly. The best my son thinks I am WONDERFUL because I fixed the TV!!!! We need more people like you helping people.... Thanks again for posting the fix.
post #27 of 87
I created an account just so I could say thank you very much to the OP! I was skeptical at first because I never get this lucky when it comes to fixing something electrical, especially a TV.

I have already replaced the lamp twice and when I turned my TV on this morning and it shut off after 3-4 seconds I was instantly pissed again. I knew it wasn't the lamp because the screen actually came on. After watching the red light flash 4 times over and over I decided to Google it. I am so glad I did!

I removed the lower back panel and took the fan out. I cleaned it really good. The fan and blades didn't come out at first. After using a flat head screwdriver to give it a little more force it popped right out. Magnets are definitely what's holding the fan to the motor. After cleaning the motor and using wd-40 I put it all back together and turned it on.

I wasn't expecting it to work because I'm never that lucky, but I was super happy when the TV stayed on. That was two hours ago and it's still working great!

A couple of the veterans on this site that are accusing the OP of making this up are dead wrong! It worked perfectly for me and I can't thank the OP enough! He saved me a lot of money and I didnt have to go a few days without my TV. Thanks again!

Thank you fixruppr for the awesome fix. I just did this to my sony xbr 50 and i am back in business. It literally took me about 15 min. If you are going into business as parallax1 suggests then you'll be successful. Curiously I haven't seen any suggestions by parallax1 for this fix. Oh by the way I'm a new member and only because I wanted to say thank you for the easy fix. I was skeptical that this would work. Maybe it won't work forever but it is at the moment. If anyone else is having the 4 red blinking power/standby light at least give this a try before you do anything else. Thanks again.
post #29 of 87
jealous maybe because fixruppr actually had a resolution to this problem. pretty sad you just can't say good job and go on.
post #30 of 87
the instructions were perfect, pretty much fixed. Except for the fan. Mine wouldn't pull apart as another poster above had the same issue. My fan model # was same as the guy above. I still cleaned everything back there, pushed some compressed air into the cracks in the fan and tried it again. It worked.

I did go and order a new fan from partsstore dot com. They didn't have the exact model, but I ordered --> (Sony 883586011 Lamp DC Fan Motor). It says it was compatible with my TV and looked EXACTLY like the one in there. Took a chance. total was 30 bucks with shipping. I'll just keep that one around until this thing craps out again.

THANKS!!!!!!!
