Can all three injectors on one side go bad at the same time


Not usually. They use the same power source but are grounded at different times by the engine computer.
Its possible one bad injector could damage the others, but that rarely happens.
An injector is an electric valve with a small coil and magnet inside.

I blew fuse in my Technic SU D7000 .iv open this thing and i cudnt find where the fuse. Where the hell is fuse in this model. Help please somebody


One of two places...either at rear next to the power supply lead usually a small black plastic screw in cap.....or on the power supply board itself which is easily identifiable as it is the glass fuse in the event of not finding what looks like a fuse then it may have a soldered in diode.you need to obtain a schematic for that make and model.and understand how to use a meter to check.

Fisher & Paykel Aquasmart WL80T65C 5 years old with fault 245, then 49.


Error code 245 is pump stall.
If the 1.6amp glass fuse has blown, the five mosfets on right side have shorted out there legs & blown the fuse.
Also check the pump drive parts for shorted legs.
There are three resistor that burn out near the fuse.
I will up loaded some pictures later.

How can you tell a fuse is blown on a samsung tv model is HP-R5072


Any fuse if glass or not can be tested with a meter that checks resistance, if glass look for the wire strand inside to be black or broken, checking a fuse is like testing a light bulb----two connections and should read a short across them.

C0500: Warm-up failure

Step 1
Check:
Fusing Heater Lamp (H1) turns
ON.

Step 2
Check:
Fusing Heater Lamp (H1) is open-circuited.
<Check Procedure>
Check the resistance across both
ends of the Fusing Heater Lamp
(H1).
The Fusing Heater Lamp is open-circuited
if the resistance is infinity.

Result: YES
Action: Change Fusing Heater Lamp (H1).

Step 3
Check: Thermoswitch 1 (TS1) is operational.
<Check Procedure>
Check the resistance across both
ends of the Thermoswitch 1 (TS1).
The Thermoswitch 1 is open-circuited
if the resistance is infinity.

Result: NO
Action: Change Thermoswitch 1 (TS1).

Step 4
Check: Fusing Unit Interlock Switch (S2) is
operational.
<Check Procedure>
Check continuity across terminals
when the Fusing Unit Interlock
Switch (S2) is turned ON.
• Across S2-1A and S2-1B
• Across S2-2A and S2-2B

Result: NO
Action: Change Fusing Unit Interlock
Switch (S2).

Result : YES
Action: Change DC Power Supply (PU1).

Step 5
Check: Thermistor (TH1) is open-circuited.
<Check Procedure>
Check the resistance across CN15-2
and CN15-3 on the Fusing Unit side
with CN15 disconnected.
The Thermistor is open-circuited if
the resistance is infinity.

Result: YES
Action: Change Thermistor (TH1).

Step 6
Check: The following voltages are supplied
from the Master Board (copier: PWBA).
<Check Procedure>
Check voltage across a Master Board
(copier: PWB-A) pin and GND when
the Power Switch is turned ON.
• Voltage across PJ10A-7 and GND
DC24 V when Fusing Heater Lamp
(H1) is OFF
DC0 V when Fusing Heater Lamp
(H1) is ON
• Voltage across PJ10A-10 and
GND
DC24 V when Fusing Heater Lamp
(H1) is OFF
DC0 V when Fusing Heater Lamp
(H1) is ON

Result: NO
Action: Change Master Board (copier:
PWB-A).

The inner door glass shattered and now no power


There's a safty switch which prevents the unit from operating if the door isn't fully closed. When the glass shattered a small piece may have blocked the switch from operating properly. Check around the door seals for any irregularities.

No power to my PSW110


The fuse may be located in several spots:

- fuse inside the three prong power plug connector on the sub (if there is one) - see if it has a fuse compartment built in - it should slide out kind of like a small drawer - sometimes it has also a separate place for a spare plug in there - the fuses used are of glass type.

- fuse mounted into a fuse holder soldered onto the circuit board - glass type fuse

- fuse soldered directly onto the circuit board - sometimes the type used is glass (it may have a heatshrink tube around it so it doesn't look like a fuse at a first glance, also there are other types of fuses that can be soldered directly onto the board - these are in the form of a small vertical cylinder, usually of a dark reddish colour with white / yellow print on the top - they look somewhat alike to small electrolytic capacitors, but are encased in dark red plastic with the pins located directly underneath the fuse.

Hope you can find it...

My bass guitar amp is blowing fuses


This sounds like the main rectifier diode/bridge is shorted. If you can rpovide the make and model, I may be able to give you more details.
