Projector blinking 4 times - Sony Office Equipment & Supplies

Not what you want to hear but this error means the lamp did not ignite. The most common problems I have had with projectors has always been the lamp itself, so if you have another or know someone with a good lamp try that first.

1 red blink every 2.5 seconds indicates a cover error-- for this check the lamp cover
2 times red blinks very 2 seconds indicates temperature error. for this let the projector cool off check filters and fans that there is no blockage of air for proper cool down
3 red blinks every every 2 seconds Power error. incorrect voltage input or internal malfunction.
4 red blinks every 2 seconds indicates Fan Error check the fans make sure they are working and not blocked or need replacing.
i have nothing on 6 ligths go ahead reconect and check for proper count. hope this information helps.
Best of Luck.

hi,
Do one one thing. check the lamp of your projector. For removing the lamp see the bellow picture.
also check the lamp colling fan. If it is faulty this fault can occur.



1. Use a screwdriver to remove the screw from the cover.(1)
2.Push up and remove the cover.(2)
3. Remove the 2 screws from the lamp module.(3)
4.Pull out the lamp module. (4)
ok

PROBLEM: The fan is broken
If any fan in the projector not move, broken, jam, the power light blinking 4 times after few second of power ON
SOLUTION: Remove the filter and then remove the upper cover
check fans and fan connector
if all fans are OK then remove the fan connector and reinstall
fix the cover and power ON projector

fan issue. make sure they are all spinning and replace as necessary.

firdt off, did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast. try projector doctor online.

i have color bands running through the picture

if it's blinking red, how many times? 1 time- lamp cover. 2 times- overheating. 4- fans. 6- lamp. if the lamp led is lit red, replace the lamp.

the number of blinks determine the problem:

Environment Over Temperature- 1 long blink / 1 short blink
DMD Over Temperature- 1 long blink / 2 short blinks
Lamp Over Temperature- 1 long blink / 3 short blinks
Fan1 Locked- 1 long blink / 4 short blinks
Fan2 Locked- 2 long blinks / 2 short blinks
Fan3 Locked- 2 long blinks / 3 short blinks
Fan4 Locked- 2 long blinks / 4 short blinks
DMD Initial Fail- 3 long blinks / 1 short blink
Lamp Initial Fail- 3 long blinks / 2 short blinks
Ballast UART Error- 3 long blinks / 3 short blinks
Temperature Sensor Fail- 3 long blinks / 4 short blinks
Inter Lock Open- 4 long blinks / 1 short blink

any of these will result in lamp off and shutdown.

4 blinks = No Vert. Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505.
