Having problems with your Sony SDM-HS93 19" LCD Monitor ?

My monitor picture comes on perfectly than goes on and off

\015 I've changed the power cord and the cable to the cpu and tried it on other computers -- always the same\015

Answers :

I flashes brightly over and over? Sounds like the Power Supply is gone or on the way out. This is caused by the Power Switch Transistor being too loosly clamped to heatsink allowing it to become too hot, or one of the capacitors responsible for filtering or frequency of oscillation is drying up and changing value. A good tech can fix either. Most likely the filter cap and AC (60hz) is getting thru. This is a $3.00 part

Or the inverter in the LCD is biting the bullet. If you turn down the brightness, does it stop or do it less often? THAT would be the invverter. Inverters take 5, 12 or 24v from the mainboard and run the itty-***** pencil-sized florescent lamps that light up your screen. Lamps are $8.00 and inverters can be $50-80, but ebay has them for alot less

Hopes that helps
