Hi. I have tse si600( 2006 year) infant incubator when I turn on it starts self test then say's turn off and call service. But when I plugged off and plagged on it shows "temperature 34 celcues Rh-0 O2-0 then power supply failure " can help me to find service manual or any help? Buy the way since i have replaced 4x 1.2v ni mh battery and bios battery it doesn't show any of them Just it was shows turned off and call service

You have an issue of the power supply board, checked the board maybe there is a loose soldered in the pcv board , check also the power Triac regulator maybe short circuit.or maybe during replacement of the bios battery the program was deleted. maybe you need to reprogram it again.

@@MohammedSohailahmed-yf9mf Is there any message in the display before it will turn off? actually this is very old machine its almost 20 years usually common issue of the old machine is the connector on the power supply board. kindly remove the back cover and check the power supply board if there is worn out connector specially the heater and fan blower connector which is usually always burn out just check it in visual.
