Question about ViewSonic PJ551 Multimedia Projector

1 Answer

Both Temp and Lamp lights blink red

Both my Temp and Lamp lights on my VS PJ551 blink red when the unit is turned on. They blink red on and off at the same time over and over again. The projector appears to be working fine (other than it's a little out of focus). I know that if the Temp indicator lights a steady red, the projector has overheated, but these lights are blinking together on and off.

All you should need to do is go to the menu on the projector, and find the Filter Timer. Hit the right arrow to select the filter time, and then hold the rest button on the projector until you are prompted to confirm the reset. Hit menu to confirm and it should now reset the filter timer. Now cut the projector off and back on and the lights should stop blinking. I hope this helps.

Red power, blinking red temp


Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.
Goodluck..

Replaced bulb yesterday worked fine. Today light will not turn on. projector turns on both lights green for 10 seconds, then power goes red and status blinks green for about 5 seconds, then status light...


green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

I turn tv on...green light comes on but i get no picture or audio....then light indicator blinks red


Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.

Viewsonic pj551 projector lamp will not light


Without more info, I'll tell you some things to check...Make sure the power cord is still plugged in firmly. With the unit unplugged, check the lamp for damage, looseness, etc. Was the unit hot when you moved it? If it was, the lamp was more prone to damage due to the heat. Always be VERY gentle if you have to move a hot projector for any reason. Did the unit sustain any hard impact while moving? Impacts crack boards, loosen connectors, and damage lamps. Make sure the lamp door is closed completely--there is a switch on the door to prevent the projector from coming on if the door is open. Make sure you didn't press any buttons on the unit too hard while holding it during moving.

Hi George86969

Try checking if all the fans are working when you swich on the unit. Normally a static red temp. light is a faulty fan that will have to be replaced.
