Supply voltage is the positive voltage supplied by the vehicle's battery + or positive post typically 12 volts. the other side is negative, if you are hard wiring an accessory in, make sure to go to your fuse panel, use a multimeter to verify it turns off with the key then get a fuse tap at a local parts store to connect.

Possible Reason:
1. High voltage power supply PCB
failure
---Replace the high voltage power supply
PCB ASSY.
2. Harness connection failure of high
voltage power supply PCB
---Check the harness connection of the high
voltage power supply PCB and reconnect
it.
3. Main PCB failure
---Replace the main PCB ASSY.

Wht kind of current comes out?


The computer's switch mode power supply produces DC (direct current) electricity.

Power light is blinking and the tv won't power up.


In that case the problem of your television is the power supply.The power supply have low voltage output so that the board of your TV cannot drive,so that the TV wont turn on.The power supply have leak capacitor that may cause of abnormal voltage.The output voltage of the power supply is +5V, +12V, and +24V.So the power supply is the problem its need to repair.Thanks

EHT + SUPPLY IS (55 OR 60 VOLTAGE) LOW VOLTAGE,MICRO POSER VOLTAGE IS NORMAL ON /OFF VOLTAGE NO ,RESET VOLTAGE NO , N O RASTER WHY


EHT should be 22 - 25KV
Power supply should supply 130Volts not 55!
Check power supply feedback loop and poor contact pre set.

MY RCA 27" WILL NOT TURN ON, HAVE POWER TO THE FUSE, THE FUSE IS GOOD ALSO BUT THE DEGAUSS RELAY DOES NOT CLICK AND NO OTHER CLICKS ARE HEARD EITHER, WHAT COULD BE WRONG?


you need to check the voltage output of your power supply section.This power supply supply is a switching type power supply.there is a chopper transformer in there.its supply is a dc voltage unlike any other transformer which is AC supplied on the primary..First step.
1.Using a multitester measure the primary supply it is a DC voltage around 220v - 110 VDC
2.Measure the secondary output.The out put is AC voltage the supply for the B+ going to plyback is 115vdc the second output is 12v run through a regulator and the regulator lower the voltage to 5vdc.this 5vdc supplies the system IC and the jungle IC.this ic process the switching of the plyback transformer and the plyback transformers output supplies the voltage of the whole system including your relay in the degaussing section....once the plyback is activated the tv will now turn on...

good luck!Hope i helped you..

please rate my help..god bless!

Printer will not turn on. power supply voltages


You should verify that your voltmeter is reading correctly. Check it against an fresh flashlight cell--it should read about 1.56 to nearly 1.6 volts. You apparently don't have an overload problem. Usually, only one voltage is the reference voltage for the voltage regulator (+5 volt?). It is entirely possible that the two supplies have a common failure. Make sure they have not been set for 220 volt AC supply.

Tv keep going on standby when you turn it on


tv goes into standby all the time if a power supply is not fine, what happens is that a power supply produces two voltages, one small one powers a standby components and bigger voltage powers a line transformer which later produces more small voltages,
then later cancels the first small voltage.

chec your power supply semi conductors like, transistors, diodes and small value resistors, on your power supply. some power supply uses a IC to oscillate a ht. so check a supply at a w/shop.

When we print manually the whole page comes out completly black.

Try replacing the toner cartridge first, then proceed with the other items.
Thank you and let me know what happens:

BLACK PAGES
DC Controller PCA is defective. If the DC Controller turns on the laser beam continuously,
the entire surface of the Photosensitive drum is neutralized causing a completely black page
Replace the DC Controller PCA

BLACK PAGES
High voltage contact springs are dirty or defective. The high voltage contacts are mounted on
the High Voltage Power Supply PCA and protrude into the toner cartridge cavity
Inspect and clean the high voltage contacts. If damaged, replace the High Voltage Power Supply PCA.

some printers have the high voltage power supply on the DC controller.

Light is leaking into the printer
Make sure that all covers are in place

My tecnics Amplifier Model # su-v98 has no power. I've checked all cords


Try these test, the only common possibilty would be the transformer and the power supply if both channels are out.You better to check both the positive and negative voltages from the power supply to see if both are present or if one or both are missing.This would be dc voltages of approx.20 to 40 volts.The positive voltage must be equal to the negative voltage,with the exception of their polarity.If one higher than the other, the regulator in power supply is busted already.The transformer can be checked for AC voltage before the power supply.This reciever uses a single power supply so the problem would be,common to both channels.You better change the regulator and checked some capacitor near the regulator.
