Good evening, please if you have a TV MOD HOMESTAR in your workshop. 21B7 and can provide me with the data of resistors R703 and R702 from where the switches to increase and decrease the volume, menu and TV / AV of the JM-2138KEY go. PCB, which put a stick and gave off the resistance mentioned and I did not get them inside and I have no other TV to verify the value of each resistor. to be able to replace it as we all know are resistance that lead to the proper functioning of the TV. The TV chassis N. is JM-2185.PCB TV HOMESTAR 20 ". Thank you to the person who can provide me with that information, wishing you a lot of thanks ...
