    if it is IC 3842 supply check dirve comming on the anode of the fet6N60

    What are the symptoms?  If the monitor comes up with an image for a short time, then goes black, it's the backlight inverter.  I got around the problem by bypassing the overcurrent trip.  I suspect that the CCFL tubes draw more current as they get old, and trip the inverter.  The backlight on the monitor I hacked is usually not on, so it's not a problem.  For a more permanent solution, I can suggest a new inverter or if that doesn't work, new backlight tubes.

Samsung Plasma won't power on

this is not a capacitor problem. set is only 18 months old - has something to do with x y sustain boards not allowing smps to power on the high voltages.

What is the the wire diagram for the 4 wheel drive system ihave no 12 volt to the switch but i have 12 volts out of the fuse panel

Power for the transfer case selector switch comes from the "GAUGES" fuse. It is fuse #4 in the left end instrument panel fuse block. This 12 volt supply goes to the switch via the "PINK" wire in position "C" of the switch connector.

Our Samsung HPN5039x Plasma TV isn't turning on: when we press the power button, the red power light flashes then turns off. What do we do?

Hello, It sounds like you have a defective power supply. Typically, +5 volt stby is present if the TV switches on with front indicator light. On the power supply, connector 802 pin 4 is the on command from the pcb main to switch the on. If this signal is present but still no VS,VA,VE panel voltages are missing, the p. supply is bad. Good luck!

Whats the value of a mitsubishi 48 inch tv, model is ws-48511?

this is mostly in the eye of the one who thinks they need one!

12 months of age 60% its purchase price if it is in good working condition
24 months 50%
36 months 25-30%
48 months 10-15%

Beyond that it will be heritage listed and bring twice the price of its original outlay and be sought after by Mitsubishi who will be amazed that they actually made a TV that lasted that long. The average life of amy Mitsubishi and quite a few other modern Tv's is about 3 years before they require huge repair expenditure.
Often better to update wvery 12 months if you can afford it as they are not built to last like the old CRT's that will still deliver on a set top box long after plasmas and rear projections have been retired.

please rate my help++++Thanks for using FIXYA

Engine wont turn over

This definitely sounds like the battery if your jeep is an 03 and the battery has never been replaced that makes your battery 6 years old most batteries average life is 3 years unless you have a no maintenance battery which will last a little longer. it should cost around 70.00 to replace I hope this has been of some help

My RCA 50'' DLP Rear Projection TV will not turn on

Hi, This could be several things as the power goes everywhere. Long distance troubleshooting so hang in there. First try a cold reboot by unplugging and replugging after 30 minutes. If nothing check P1 on the light engine for the following voltages: pin 2 5vdc, pin 3 3.3vdc, pin 9 3.3vdc, pin 12 12vdc. If any of these are not good it is the formatter board. If all are good, does the color wheel spin at all. If this is OK then check J4 on the light engine, the ballast enable line should be 0 vdc in stby, .5 vdc at turn on, and 2.5 to 3.25 vdc in run. If good, is the light engine trying to fire the lamp? If not, inspect the J4 connector and the lamp power supply, If they look OK then the lamp ballast is probably bad. This will give you something to do for now, Good Luck!

Television lines

This sounds like a bad cap in the power supply. The component is only starting to fail under load and heat. I'll look up your specific model and see if there have been any reports of this type of problem.
