Check the B+ about 115vdc.Check collector voltage of horizontal output transistor.If there is voltage over 115vdc from B+ and H-out collector voltage, there should be little light produce on the screen.If not , measure the supply voltage of the heater-from CRT.If there is voltage supply at least 4vdc, then check the switching transistor near flyback. FET or MOSFET transistor for shortage or no supply in triggering gate terminal lead.If not resoldering the IC in the CRT board or any other probable parts .The last I think, check the resistance of the heater CRT pins.If no resistance reading , then your crt tube is deffective. The last is the so-called jungle IC that many video problems comes out.Try to resolder the IC pins.Check the transistor that surrounds the IC. Sometimes If test the transistor , there is no shortage and no leakage, but it don't oscillate. Therefore no video display.

The sampo alphascan 411 has not picture the screen is black. Turns on but no picture.


Open it up and look at the capacitors. The round "tin can" looking components. If the tops appear bulged, then replacing them may help. Check out the YouTube video... and web site...

My monitor Goes blank after about 2 seconds


Dave, You failed to state if these monitors are LCD/FPD or are they old tube type? I'm going to assume that they are of the flat screen lcd type. all monitors of the lcd type need what is called 'backlighting' to display the video information. In your case, maybe the inverter power supply board has detected a fault and go's into immediate shutdown mode. the inverter supply is what lights the long slim cold cathode fluorescent tubes (2) that are used for lcd backllighting in 98% of all small screen lcd monitors. There isn't a lot you can do about these types of failures. You can check with Sampo and see if they have a swapout program where you send old monitor plus some cash and they send you a refurbished ( new tubes+inverter board ) monitor. I myself kinda lucked out when a co-worker brought in his Dell lcd. we opened it up and found some bad capacitors that couldn't take the heat generated inside the case. Yes we unsoldered and replaced them with new and it worked. But that was pure luck. could have been a lot of other things wrong too. you might want to surf around and check out slectronics.net/ or other sites that deal with monitor CCF tubes and inverter repair. the lighting technology you are dealing with is similar to the new 'curlie-que' energy saving-screw-in light bulbs! Hope this helps you out some. I'm lmistyrel @ aol or louie12fix on fixya.
