For sony SDM-M51 monitors try pinching the the screen on the plastic bezel, about one inch above the speaker holes on the audio output side of the screen. Move up and down a little. If the picture comes back on the problem is the lcd connector to the monitor electronics.

Re: SDM M51 major problem

Based on your post/description, the "fizzling noise and a smell of ozone" are indicators of electronic component(s) that burned. Should you be comfortable and have a fair knowledge of component level repair, soldering and the use of a VOM then it is possible to repair it yourself. The inside would basically be divided into 3 electronic group; 1. power supply; 2. video; and 3. illumination. This should be fairly straight forward since the "fizzling noise and a smell of ozone" indicators would also be visually apparent. Fizzling would normally be capacitors leaking their oil at high temp/high pressure. this would probably be in the power supply section (but the other 2 groups have their own capacitors also). Smell of ozone would usually come from high voltage arcing which is only present in the inverter circuitry of the illumination. It is the group responsible for supplying the high voltage high frequency supply of the small fluorescent tube (CCF) that provides the backlight of the display panel. As earlier mentioned, it has also its own capacitors. If for some reason you do not feel comfortable opening and working the electronics inside, you might be better off seeking the services of a qualified professional. Good luck and kind regards. Hope this gives you and idea and how to go about it.

My monitor doent turn on not even with the power cable.. what to do?

The monitor has a power supply problem and often developes bulging capacitors which become open, and there are usually other underline issues that make the repair not cost effective to fix. The only thing I can suggest is have it checked with an estimate so you can make a personal choice.

No picture Display when turned on lots of Colour lines, could this be the inverter board problem. the model is Sony TFT LCD Color Computer Display SDM-X72 Serial Number 4530624 Manufactured April...

This is not an inverter problem. The inverter only powers the fluorescent lamps in the back of the LCD panel.

It is probably a fault in the LCD data decoder circuit or a failing connector between the decoder circuit board and the glass LCD panel. If you took it in to a shop, they would probably charge you a full hour's labor minimum - compare that with the price of a new LCD monitor.

The cheapest method of all.
Make sure your PC is plugged into a power strip and after windows shuts down just hit the off switch on the power strip.
Unless you want to shell out some cash for a new power board for your monitor.

Monitor goes blank

Well, I do not think that there is an actual solution for that problem. I had that exact problem and I had to throw mine away. Turn it in to where you bought it and see if they can repair it. Otherwise they will have to replace it.
