We have the same problem.. Checked the Sony site after a few clicks got to:,/?St=966,E=0000000000761838071,K=1708,Sxi=1,Case=obj(460991),VARSET_OBJ=460991,VARSET_TSRC=results,UseTemplate=case.tem,VARSET_TOP=TRUE
We followed the 'simple' troubleshooting tips then called the service center. As mentioned above 4 blinks indicates a bad panel. The repairman that visited said that he is ordering a new power supply (much cheaper than the back panel) for their first try. I will post again when my set is back on.

  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

    SOURCE: Sony PS-LX300USB Turntable, one channel not working

    Have you tried swopping over the output leads from the turntable to the amp (normally one red and one white phono plug) so they are in each others socket? If you do this and you still get no sound from the right channel it is almost certain to be a faulty amp,or speaker.
    If you swop and get no sound from the LEFT channel it is could be either a faulty lead or cartridge.

    SOURCE: sony vaio vgn nr160e laptop - no display

    You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
    To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, usually the CCFL lamp fails before the inverter.
    The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

    Loud high pitch noise

    The noise could be from the fly-back transformer.
    There are very high and dangerous voltages inside a CRT monitor.
    As you are not an electronics technician, I suggest you do not try to fix it yourself, your eyeballs will light up if you poke your fingers in a wrong spot.
    Get a quote for the repair, but the cost of monitors these days are fairly cheap and a repair may not be a cost effective solution. Consider getting a LCD monitor, they take up less room and they are very energy efficient.

    Monitor Goes black, or flickers on and off

    The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

    There is a loud buzzing/static sound coming from my monitor. It changes pitch and sound a little with different screens. The visual display does not seem to be effected. Just a terrible sound. Any ideas...

    Start by getting a can of the electronics spray air and blowing out and areas that may collect dust.

    Also jiggle the power cord attached to the monitor and watch to see if it changes the monitor or the squealing at all.

    Seems more like a lose power connection, but eliminate the simple possibilities before moving toward circuit board issues etc.

    Also do you have any other high powered electronic devices near the monitor?

    That can effect it's performance as well.

    Refrig shut off and will not restart - light bulbs still working

    this refrigerator sounds like a 'frost free' type, and as such can, usually, only be repaired by the manufacturer. local refrigeration engineers cannot get the parts. your fault sounds like a PCB (printed circuit board) has gone, which only the manufacturers have in stock.

    The "terrable loud high pitch sound" could be the horz. oscillator.
    The voltages off the crt should be (+) (-) 11v to 15v DC. Too much on Blue & Red guns will cut them off
