Fujitsu P55XHA40US powers off after 5 minutes, led blinks 1 time red 3 times green, what does it means ?

Throw away

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The
table in Figure 4-3 list the User Initialization procedures.
Note: Pressing INPUT and FORMAT is the same as
the Initialization in the Option Menu (MENU-2-4-7-0)

Had similar problem (ie. 2 green & red flashed followed by 5 red flashes - Fan blowing but not cooling ... I also noted that the outside unit fan wasn't going). Tried restarting several time after waiting only a minute or two after turning the mains power off but with no change. So turned the unit off at the mains power and then fired it up about 2hrs later and it was all working fine.

The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

Power LED Blinking timing chart
When an abnormality has occurred the unit, the protection circuit operates and reset to the stand by mode. At this time, the defective block can be identified by the number of blinks of the Power LED on the front panel of the unit.

E5 means cartridges error - to fix press the "stop\reset" button for 5-7 seconds and then release it.

You can also try this:

1) With the printer power turned off but connected to a power source, while pressing the Resume/Cancel button, press and hold the Power button.
(DO NOT release the buttons. The Power LED lights in green to indicate that a function is selectable.)

2) While holding the Power button, release the Resume/Cancel button. (DO NOT release the Power button.)

3) While holding the Power button, press the Resume/Cancel button 2 times, and then release both the Power and
Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed, the Alarm and Power LEDs light
alternately, Alarm in orange and Power in green, starting with Alarm LED.)

4) When the Power LED lights in green, press the Resume/Cancel button the specified number of time(s)according to the function listed in the table below. (Each time the Resume/Cancel button is pressed, the Alarm and
Power LEDs light alternately, Alarm in orange and Power in green, starting with Alarm LED.)

4 times----Green (Power)------Waste ink counter resetting

Thats an error code, but I will need the model number to help you identify what the 5 blinks mean

Service manual says 3 flashing red leds = eeprom error (main digital / video pcb).
Suggest you start by implementation of Fujitsu Service Bulletin PDP 0068-01 Main Digital pcb see:-ttp://www.eserviceinfo.com/download.php?fileid=43450

Hi,
Thank you for contacting Fixya.
You need to check the blinking times of the Paer jam LED. Then check the followings:
1. If the lamp is on, then ADF Switch is malfunctioning. Disble or short the switch.
2. If the lamp is off, then it is Flatbed or ADF Inverter error. Lamp inverter circuit is to be replaced.
5. If the Lamp is still off, then Lamp is to be replaced.
6. If the issue still persists, then you may have to contact the authorized Avision Service personnel for further diagnosis and suggested repair or replacement.
Hope the above information is helpful.
Please revert if you have any doubt.
Regards,
TechSatya

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
