Its easy to repair. Some parts that needs replacement are the blown and bulge capacitor in the power supply section on the monitor. They are the very first to be affected when something goes wrong. The others where the inverter transformer and the inverter light. Very cheap to repair, the labor is the one that cost that much. Bring it to a nearer technician in your area and it will be repair in no time

Very doubtful. Either you have a defective or corrupt display driver, or possibly a malware infection. Is that a laptop or notebook computer? If so, is there a VGA port for an external monitor? If do, try using a known good external monitor.

My Sony SDM-HS74P display does not stay on.


I have the same issue and wrote the monitor off for now after checking all cables (and a different computer). The logic circuitry and panel are sill ok as I can see a faint image with proper lighting and close inspection, but no backlight makes it useless.

Since there are 4 lamps (CCFLs) on this model, the problem likely is not there but on the inverter circuitry driving them. This does not look easy to replace as this is part of a bigger board.

It looks like some could repair by changing a few (or even one) component on the board, but unless your are used to this (de-soldering and soldering back), you are kind of stuck.

I will attempt this if I have time as I hate junking 99.9% ok hardware. In your case since this is an old monitor you should just replace it if not technically (on the electronics side) apt.

You open the inverter unit and check any dry soldering is there. Some times dry joints inside the inverter unit cause this type of problems.

Sony SDM-HS74P/S 17 - Monitor won't stay on the right picture


When the screen turns black again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself. Let us know what you find out and please don?t forget to rate this posting.
