Cs 40507 won't power up

Opened up the back because nothing is lighted and thought maybe it was the power switch was defective but not sure? unit is showing power through the power cord though with an electricians power sniffer so I know power is going to the TV but like it's not going through it and also checked fuse and it's fine so what do you think it could be?

SOURCE: CS- 40503 No Power

There is no external reset, and if the set is completely dead (not even a click when the power button is pressed) then there is probably an open main fuse or defective stand-by power supply. If the main fuse is blown then there is usually a heavy short in the main power supply, and either way the set should be looked at by someone with experience in Mitsubishi sets.

SOURCE: ws-65819, No response, Not even the blinking green light

To repair damage--you understand the foil at each connection is copper---you have to scrape some of the green coating off near the parts and solder the exposed foil---idea is to solder a wire across any gaps to complete the circuit.

Got it?

Mitshubishi WD-62327 TV will not turn on and no sound. TV made a interference sound and shut off. Tried to turn it in the morning still nothing. Replaced lamp/bulb still nothing. Red light is on (not...

If you have a voltage meter there are some things you can check.
Unplug the unit and remove the back cover of the set. Then Plug the unit back in.
You will need to tape down the lamp safety switch in order to do these tests.
Here are all the failures that would give you a lamp error and what to check.
Cause 1. Unit powers on and works properly for a while then shuts off with a red lamp led(lamp error). Suspect bad lamp and replace.
Cause 2. Unit does not power up correctly and you have red lamp led(lamp error). Check the lamp enable line at connector J14 on the back of the light engine. If pin 6 does not switch to 5 volts after turn on, but your 12 and 5 volt supplies are good, then suspect a defective light engine.
Cuse 3. At power on the lamp turns on and off 3 times and then the unit shuts down with a red lamp led(lamp error). You have a defective light engine.
Cause 4. Unit does not turn on correctly and you have a red lamp led(lamp error). Check for 12 volts at connector J9 pin 4 on the light engine. If voltage is missing check for an open fuse F9A09 on the power supply board. If it is open, then you need to replace the fuse and you still have a defective light engine.
Cause 5. Lamp enable line at connector J14 pin 6 on the light engine does go to 5 volts at turn on, but does not drop back to 0 volts after 5 seconds, but your 12 and 5 volts supplies are good then you have a defective light engine.
Cuase 6. Check for 5 volts at connector J9 pins 1 and 2 on the light engine. If low or missing check Capacitors C9A37 and C9A38. Values are 3300MF/10V. Replace capacitors if defective.

This is all I have and I wish you luck.

I has a Crosley Washing Machine Top Loader. Fill light comes on lid locks then NOthing!

seethis causes and fix it. God bless you
User Control and Display Board If the washer won't start, the user control and display board may be defective. Check for power to the washer first.
Timer If the washer won't start the timer might be defective. This part is often misdiagnosed, check other components before replacing this time
Line Fuse If the washer won't start the line fuse might have blown.
Thermal Fuse If the washer won't start the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.
Line Fuse and Holder If the washer won't start the line fuse might have blown, or the line fuse holder might be damaged and need to be replaced.

Door or Lid Latch Assembly If the washer won't start the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Door Lock Motor and Switch Assembly If the washer won't start the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.

Incoming Power Problem If the washer won't start check to see if there is power at the electrical outlet which the washer is plugged into. Plug a lamp or radio into the outlet to check it. If the outlet is dead, check the circuit breakers or fuses for the hom
Power Cord If the washer won't start, check to be sure there is power to the electrical outlet for the home. If that is OK, the power cord itself might be defective. This is rare. You can check the power cord with an Ohm meter for continuity.

Flay back tv mitsubishi model cs40507

Mitsubishi has offices in Brazil. Apparently, they are out of the consumer TV and consumer entertainment business for a number of years now.

With the phasing out of CRT television sets, I have my doubts you will find a flyback unless you can find a scrap TV of the same model as yours. You can also try eBay or others like that to see if you can find this part.
