Sony KDS R60XBR1 red light blinking 3 times. Replaced lamp, cleaned all vents, replaced cover door properly.. What else?

You may need to take off the back cover and clean the fan and if you can, put a little oil on the fan shaft. I also use a small vacuum to get more of the dust out around the fan. You can blow out some of the dust but be careful as you don't want to blow dust into the lamp area. When you take off the back cover you'll be amazed at the amount of dust in there!

Does radiator fan blow towards or away from radiator


During normal driving, the fan will be off, because air is being pushed through the radiator. When stopped, the fan will cut on, pushing air through the radiator and cooling the engine.

Also, make sure the radiator fan is on the inside (engine side) of the radiator, so it is not blocking the air during normal driving.

The projector temp. indicator light come red and the machine cannot boot. the fan rather blows high. please can you help me?

Possible that the projection lamp is faulty if the filter is clean and the fan blows well. You can remove and set back the lamp while doing so checck if there is any broken particles inthe lamp.
if so the lamp has failed for sure.
If not get a replacement/ or swap, to test and confirm.

Optoma HD 70 turns on with lamp and temo soiled lights

Asher fadida and alll,

The issue:
solid red error light?
HD70 "die's" after few min with strage noise?
flickers different colors before complete self shutdown?

well try this....

Before replacing your bulb, fan or any other component try first cleaning your optoma realy good!! HD70 doesnt comes with any kind of filter so you can imagine the amound of dust can be.
The most importent thing is to blow away any dust from your color wheel + the sensor attached to it .

for farther troubleshoting clean your fan's.
there are 2 fan's insinde the HD70.

probably the most problems will be solved by cleening the color wheel!!
if the problem is not solved ,chack the lemp and the fans if they work properlly.

For fan replacing:
Fan Part number: GM1207PKVX-A

Good luck!!

Single phase appliances only turn in one direction. Try cleaning your condenser to get better air circulation. Sounds like your compressor went out on head pressure.

My SonyGrand Wega lamp is inserted properly yet sets off sensor

3 blink error = lamp door.
if the lamp door melts and deforms, you have a clogged fan that cools the lamp. then the door won't hit the lamp door switch. the right way to fix is to replace the lamp door and the fan, but you could clean out the fan and just hard wire the lamp door switch to think its closed to fix the problem. just remember that the switch is there so you can't open the door while the lamp is on and burn your eyes with the UV. you can put a jumper wire in the connector that hooks to the wire to the lamp door switch to bypass. cleaning the fan is easy as long as no smoke or grease is mixed with the dust. remove power to the set, remove the back and front as well as the lamp door. take compressed air and spin the fan up to blow the dust out the fan, it will blow straight out the lamp door hopefully. when you look into the back of the tv, the fan will be just above where the lamp is, on top of the engine. it is a non-typical scrirocco type fan.

Overheating when I know it has not been on.

one of the internal fans might be broken, if even one of them stops, this problem will occure!
there are 6 fans in this projector.
check also if the metal handle is folded towards the lamp housing, if not it can stop the large exhaust fan
mounted on the lamp door on the rear side of the Pj.
