I have a RCA Projection screen TV Mod#P52754AT Ser#643580021. Will not power on with or without remote. Minor trouble shooting performed. Pls any help you can offer would be greatly appreciated. Ken


First thing I would verify is that power is being sent to the TV.
Check circuit breakers ect.
If you have a multi-meter verify there is AC voltage at the outlet the TV is plugged into.

If you do have voltage the next step is to verify the power supply / HV spliter is sending voltage.
Below is quick video on how to do that.
If components are bad, replace or repair them.
If it is good your problem requires more complex troubleshooting and a circuit diagram.

Be sure to check the output transistor. This is the most likely the cause. It is by the flyback, on a heatsink.

On a Sanyo DP58D34, it has no sound, and no video, but the green power light comes on when turned on and you can here clicking coming from back of tv when you turn it on. What would cause this?


Sound like one of your circuit boards has a bad connection or bad component and the low voltage circuit that powers the tuner is not working. The high voltage circuit that powers the picture will not power up if the low voltage circuit fails.

Low voltage to starter


What testing did you do, to find the voltage was low,
to the starter solenoid, I assume?
Have to have a wiring diagram & do voltage drop
testing of the circuit you suspect to be a problem

Need wiring diagram for a marathon 1/2 hp electric motor 220 to 115volt


HAVE POWER TURNED OFF AND LOCKED OUT. If the motor is a dual voltage motor it should have a wiring diagram on the motor. Check on the name plate of the motor. You should see a high and low voltage diagram. Follow the low voltage numbering. The widings need reconfigured to operate at a different voltage. Hope this helps you...Jim

Gps not turning on/starting


I have the same problem. It may have something to do with battery. Try to charge it via your car. Or get a Garmin and never buy a Sanyo GPS again.

VOLTAGE


These appliances are rated for 208 or 230 volts, so the min/max voltage rating would be min 188 v and max 253 volts. Hope this helps

How many pictures can you take with alkaline batteries?
The initial voltage of NI-MH is low and when it discharges, the voltage drop lower to a point where it is not high enough for the electric circuits of the camera. Alkaline batteries hold their voltage better.
Try SANYO eneloop recharchable batteries. They don't drop their voltage.

This looks like a power supply problem. I would advise checking the high and low voltage power supplies if you have a background in electronics. If not (I know this is not what you want to hear) take the set to a shop. I have said this many times and I'll say it many more times. TVs contain voltages that can kill you, not give you a bad scare, but kill you and I don't mean Hollywood dead, I mean really really dead. That being said this looks like the voltages have dropped so low that a full picture can not be mainained.
