Question about Sony KP-53S70 53" Rear Projection Television

1 Answer

Can't find the cooling fan

I got a tip on here about blowing out or cleaning the cooling fan, but can't seem to find it. Am I missing it, or does this model not have one? P.S. it has no picture, and LED blinks 4 times then stops and blinks 4 times.

Unfortunately, you apparently got information from someone who has not had training on your set. A 4 flash on your set indicates a vertical stop, meaning that the vertical drive circuit has shutdown. Possible causes are a bad vertical drive or vertical output IC. I can't be more specific because I would have to check a couple of things, starting with the 135 volt power supply line to see if it is coming up. You can stop looking for a cooling fan because this set does not have one.

I have cleaned the fans in the back of the tv and the light still blinks four times. I have lubricated the fans as well. What do I do now?


You said you "cleaned" the fans. Have you tried removing the large fan -- on the left side when you are standing in the back of the TV -- and actually pulling out the fan itself? One side of the fan casing has a sticker -- with the model number written on it -- and the other side is the fan itself. Carefully pull the fan out -- it's held by magnets, no screws -- then clean the spindle thoroughly with a Q-tip dipped in rubbing alcohol. Also, clean the opening on the casing itself -- the hole is too small for a Q-tip, so use a toothpick, again dipped in rubbing alcohol.

For additional cleaning, use compressed air to blow the hole. After the alcohol dries, use another Q-tip and spray a little WD40 on one of the tips. Sparingly apply the WD40 to the fan spindle. Place the fan back into the casing, screw the cover back on and try the TV again.

Good luck!

Phillips 50P8341 will stay on about 15 mins then shuts off then the power button flashes twice, pauses then flashes twice again...


Seems like it is overheating. Try cooling it down by using a fan to blow air into it (temporary fix). Make sure the TV is well ventilated and heat can escape (permanent solution).

Sony Dlp, 46" shuts off, cools off, then turns


This is probably a heat issue (assuming you aren't the one turning off the TV and aren't having regular power failures). This TV has two fans to help keep the components cool; if the temperature increases, the TV will shut down to protect those components. Also check if the ventilation slots are blocked and clean the dust off them. (When you have the TV open, you can blow out dust as well - much like dust removal for a desktop CPU.)

For replacement fans, you can go here: http://www.partstore.com/Model/Sony/Sony/KDF46E2000.aspx .

I hope this helps.

My TV keeps blowing the lamps. Gone through 2 in 3 weeks. I bought the TV in January 2008. Is it time to get a new one?


ok.. my first instinct for this problem is airflow... check to see if the filter is cloged or blocked...make sure the fan is blowing to cool it. if this all seems right then you might have what is called a faulty ballast. which may need replaced. or the fan might be jammeded.

Tv has sound but no picture.


Yes, dust is the number one cause to all electronics, i recommend using compressed air to clean the inside every month or so.

Cooling fan in rear does not seem to work, unit may be overheating.


Yes the fan activates when the TV gets a certain level of temp now if this never comes on it would need to be replaced with a new fan motor. I would keep a eye on it if you TV seems to be too darn hot because this can cause falures if it does not cool off the unit.. Thanks and please rate.

I have the answer for the fan issue on the KDSR50XBR1!!!!!

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...

What do you think? Spread the word, lets save some folks from spending needlessly...
