Power unit not ready - Inverter KEB COMBIVERT F5

Unfortunately that is 2 different errors... One being easily fixed. The 5 blinking power LED means its time to replace the Lamp, thats the easiest one to fix.

The blinking ready light means a "Fan 3 error". There is no reference on what that could be. It could be as simple as cleaning the air filter, or as complicated as replacing one of the fan units. You will need to contact Vivitek to know for sure:

Attached you will find a chart for diagnosing the Power and Blinking Ready Lights:

This is a failure of the power supply unit. SMPS unit. Please check this link for tips:

could be a power supply failure or a control issue. I would take the unit to a repair shop and see if they can provide you with an estimate. You could try to buy a replacement power board and install it on your own if you are mechanically inclined.

Yurn the unit off for a few minutes, Then back on Use the controls and leave the unit plugged in. Good Luck, Ned

It sounds like the unit is tripping the breaker because the breaker is not rated high enough to handle the heaters power usage! If its not that then it may very well be the thermostat needs replaced in unit!
Test at a friends house to see if its your system or the unit!

When the flash goes into battery saver mode, which it does automatically, the light will blink.
If you are using the external power source, the light should remain steady.

Have you cleaned the filters? In this situation, the fan and power shuts down even before the bulb lights up and heats up the unit, but perhaps the unit can detect clogged filters.

You can download the manual here if you don't have one. Instructions for cleaning the filters are on page 37.

Had this same problem. the "not ready" message flashes, unplugging the unit, pushing the power button have not impact ont he message. Keurig tells me this is an indication the heating element has burned out. I had ot call in a warranty claim and get a replacement.

Yes I had this problem. Unplug the power cord for 1 min then plug it back in. The tv will reset and the buttons then work again.
