Resistor Identification or circuit diagram for wireless subwoofer

If your TCL TS9030 subwoofer is experiencing intermittent sound and crackling issues, it could be due to a variety of factors. The first thing you should try is checking the connections between the subwoofer and the other components in your home theater system to ensure that they are secure. It is also a good idea to try a different power outlet or power strip to rule out any issues with the electrical supply.
If the issue persists after checking the connections and power supply, it is possible that there may be a problem with the subwoofer itself. In this case, it is worth checking to see if the subwoofer is still covered under the manufacturer's warranty. If it is, you should be able to have it repaired or replaced free of charge.
If the subwoofer is no longer covered under warranty, you may need to pay for repairs or consider purchasing a new subwoofer. If you are not comfortable troubleshooting the issue yourself, you may want to consider seeking the assistance of a qualified technician or contacting TCL for support. They may be able to diagnose the issue more accurately and suggest the appropriate course of action.

You should check the new cable wiring connections. There is a resistor in that microphone that connects to the channel button circuit, it is (electrically) between switch 5 (up) and pin 3. If this not present then it may be causing your issue, IT is also possible that the diode for that circuit (located on the main board) got damaged when the cord was cut. diagram: http://www.cbtricks.com/radios/realistic/trc_476/476_print.htm

you should be able to get a new R12 resistor at radio shack. be VERY careful when heating the solder up to remove/replace the resistor. Hope this helps!

Your driver has a damaged voice coil, you can either find a speaker repairer to replace the voice coil or find a replacement driver to fit.

Should be a issue with your stereo not the speakers

The heat cut's out ? The heater blower motor stops working ? Testing the electrical circuit would be the proper way to diagnose . Looking at a wiring diagram an using a DMM - digital multi-meter , an doing amp draw test on the blower motor . The PRND321 an blower motor probably share a ground or power point . Looking at a wiring diagram for both circuit's would show that . Not a short , more likely a loose ground connection .

is that resistor in the line to q12 ? if so it should be in the spec sheet for that device. if you don't have the spec sheet then let me know what q12 part number is.

Usually, when the fan works only on high speed the issue is with the blower motor resistor. It will be located under the dash close to the blower motor itself. It will have a multi-wire plug and feeds signal to the blower motor. An updated resistor maybe available in which case a slightly larger hole will have to be cut for the new resistor. This is not a difficult proceedure, only a couple of screws are holding the resistor in place and most resistors are resonably priced. I recommend you buy the resistor at the dealer, this is a case where you get what you pay for.
Good luck, hope this helps.

Hi fccjben;

The color code is as follows: blk = 0; brn =1; red = 2; orange = 3; yellow = 4; Green = 5: blue = 6; violet=7; Grey = 8; white = 9

Unfortunately, if it is wirewound, they usually printed the resistor value on the body of the resistor. For sure it shouldn't be glowing. Sorry I can't be more help, but without a schematid, can't do much else

Good luck Loringh
