Fix my problem get sy cf on my display

Hello Eric espy, thanks for your post!

From my understanding you used the icemaker on your Frigidaire refrigerator and now have a code of "SY CF" on the display. That code of "SY CF" stands for communication failure after power up. This could be a possible communication error between the UIB (User Interface Board) and main control board. I would suggest performing a reset, which should clear any false error codes. If you continue to receive the error I would suggest contacting a professional technician for proper diagnosis and repair. This may help you avoid unnecessary part purchases. -Matt

Microwave keeps shutting off after a few seconds and error number H97 shows up on display pad. What does this error mean?

Error code H97 is an indication of a possible failure of the Magnetron, DPC board or the High Voltage Inverter board. It could be just a loose wire connection also between the DPC board and the High Voltage Inverter board.

This failure will require a service technician to diagnose and repair.

Have no picture or sound on aoc hdtv aoc l42h961?

Is the power cord plugged in all the way? Try a different power cord if you see no indication of power. If that doesn't fix it, you might have a bad power supply. Electrolytic capacitors in the power supply are a common failure component and it might be cheaper to repair than to replace. I am a repair technician and was able to repair my two AOC televisions for less than $3 by replacing 4 electrolytic capacitors. You will need to pay a technician for parts and labor.

F20 error code on Frigidare electric range

Hello rjshomesnj - Typically error code E20 indicates that the range has detected a communication failure between EOC (electronic oven control) and ESEC system (electronic service element control). In other words, the range has an issue with the switch for the burner. I will personally recommend contacting a certified technician to move forward accurately and to assist with the repairs. You can often locate qualified servicers by visiting the manufacturer website.

Frigidaire plef398dca

Hello Bill Robbins - From what you are describing it sounds like a wiring failure or a communication break failure between the power board and UIB has occurred. Error code F5, typically indicates that the EOC will need replacing. A certified technician will need to test the wiring harness between the ESC, UIB and EOC.

Panasonic tv plasma blinking red led

This is what it says on Panasonic's website:

"Panasonic utilizes the blinking light as a form of self-diagnostics, similar to the "check engine" light in your car. If you've ever experienced that, you know that a check engine light could indicate anything from a loose gas cap to a major failure.

Panasonic uses the number of times the light blinks, to aid the technician in trouble-shooting the problem. The blinking light indicates an area of concern and helps the technician to isolate the problem and order the correct parts. This in turn speeds up the repair process, keeps parts cost down, and helps both you and the servicer by allowing the technician to complete a repair in one trip in most cases."

You'll probably need to call a repair man to fix your TV.
