Need to replace internal input for power source on Ironman240r

There could be several reasons why your TCL TV is displaying a black screen after being powered on. Here are a few possibilities:

1. Power issue: If the TV is not receiving sufficient power, it may not be able to fully turn on and display a picture. Make sure the TV is plugged into a working outlet and that the outlet has power.
2. HDMI/AV cable issue: If you are using an HDMI or AV cable to connect your TV to another device (such as a cable box or a game console), the issue could be with the cable or with the device. Try using a different HDMI or AV cable to see if that resolves the problem.
3. TV settings: If the TV is not set to the correct input source or if the picture size is set incorrectly, it may appear as a black screen. Try pressing the "Input" or "Source" button on your TV remote to cycle through the available input sources and see if that fixes the problem.
4. Defective TV: If none of the above suggestions fix the problem, the issue could be with the TV itself. It is possible that the TV's display or some other internal component is defective, in which case you may need to have the TV repaired or replaced.

I recommend trying the above suggestions to see if they resolve the issue. If the problem persists, you may need to consult a TV repair technician or contact TCL customer support for further assistance.

My Vizio Has a Blue Screen But Doesn't Shut Off Troubleshooting your Vizio TV requires that you first identify the source of the problem. A blue screen on your Vizio TV can indicate that you are experiencing a problem with the video input on your TV, while the failure to turn off may indicate that there is a problem with overcharged internal memory or your power capacitors in your TV.

Finding the cause of your Vizio's problems can involve trial and error.

Check Your Connections The connections leading to and from your Vizio TV may be responsible for your Vizio TV having a blue screen and failing to power down. Tighten the coaxial connections to your TV and firmly press in any HDMI, component or composite video cables connecting to your TV, then check the signal on your TV to see if the blue screen problem resolves itself.

Discharge Your TV's Memory Overcharged internal memory can lock up your Vizio TV and prevent it from changing channels or turning off. To discharge your TV, unplug your TV and press and hold the "Power" button for 30 seconds. Plug the TV back into the electrical outlet after 30 seconds and check to see if the problem persists.
Change Input
The input source connected to your TV may be malfunctioning and preventing your Vizio TV from powering off. The "Input" button on your remote will allow you to select a new input source. Cycle through input sources until you find one that displays an image on your screen and power the TV off. If this method works, you may need to replace the input source preventing your TV from turning on.

Power-Cycle Your Equipment Power-cycling your equipment can solve errors created by devices or with your TV's power supply. To power-cycle your equipment, unplug your TV from the electrical outlet along with any devices connected to your TV. Plug your TV back in and turn it on. Plug in each device, one at a time, and notice if your TV displays a blue screen or has trouble turning off. Repeat this process for each device connected to your TV and replace any devices causing problems with your TV.

Cost by replacing the amps would NOT be cost effective.

In looking at the schematic, assuming there was a voltage surge on input power, possibly the diodes and capacitors in the power supply are damaged if the fuse blew and was replaced.

If the speakers were powered by a different receptacle than the source feeding the audio to these was, ground bounce may have destroyed the first input stage.

You need to give us current symptoms so we can direct replacement of bad components.

YOU SHOULD CHANGE THE CONNECTOR BEFORE IT BLOWS UP THE POWER IC'S THAT LINK TO THE CONNECTOR
IT'S A BIT LOOSE

Chek the speaker continuty with a multimer , Audio Input connector/Cable,next check the Audio out put Chips Voltage +5V pin # 6, If ok then replace the Capacitior at pin # 4 (2.2MFD 25V)..

Sorry it took so long to reply to your problem.You must try to reset the Clock/Radio's microprocessor. To do this you must disconnect the Clock/Radio from the A/C power source and remove the internal battery. Let the Clock/Radio set without any power source for about 3 hours. This should completely drain all the power from the microprocessor. After this is done, reinsert the internal battery and plug the Clock/Radio into the A/C power source. The Clock/Radio's functions should return to normal. If they do not return to normal. Unplug the Clock/Radio from the A/C power source and remove the internal battery. Replace the internal Battery (CR2430). Let the Clock/Radio again drain all the power from the microprocessor. Insert the new battery and Plug the Clock/Radio into the A/C power source. The Clock/Radio's functions should return to normal.If you should still be having problem with the functions of the Clock/Radio, you will need to call Emerson Customer Support. The telephone number for Emerson Customer Support is 1-800-909-1240. Call them between the hours of 8am-4:30pm CT. Give them the make and model number of the Clock/Radio and ask them for assistance with your problem. I hope this information help you with your problem.
