Question about Philips 150S (White) 15" LCD Monitor

1 Answer

It started failing, now is dead.

In the past, my 150s monitor sometimes was failing. It didn´t . Just didn´t switch on, or sometimes switch for 1/2 second and swiched off. Other times swithed but the screen got totally blank, keep white while image disappeared and then switched off. The problem disappeared when putting the panel on a dry enviroment, or on a place where the sun gives it some heat, so I thought was just humidity. Now, doesn´t switch at all. Anyone knows posible solution?,

    Keep it where it is warm and dry any room will do
    so long as it does not keep you awake at night - in which case switch it off or turn it to the wall ;-)

No start ,dead

Hi alonzot,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the link for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

You may also replace the power supply board, try online like and

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using fixya.

mohanjith, First thing to investigate is the lcd monitor internal power supply for failed electrolytic filter capacitors on the power supply circuit board. If swollen and leaky, then you might try to replace the bad ones with new ones. Visit YOUTUBE for video clips to see if you can do the investigation/repair.

Power window systems failing in past few months. 3 of 4 now dead.

before spending alot of money on windows motors, try to take out the switch in the door handle and spray contact cleaner in the switch.. sometimes if you use alot of armor all on the door panels it will work its way into the switch and make it dirty.
