Re: TV won't turn on.
Its a possibility that the micro could be bad BUT most likely the standby power supply or the running power supply is bad as the regulators go bad alot in these. Also i dont know if this is one of the serial #s that the horizontal output would blow out and cause this problem because of the mounting screw came loose. If your not a tv or electronic tech, there are hundreds of volts inside this puppy ,so I would recommend that you take to a pro. Good Luck

Hello The LOT [Line Output Transformer] of your TV. It should be replace with same type and number. Actually this is a skilled work. You have to unsoder this component out from the circuit board, and to resolder the new one in place. Have to adjust the perfect screen and focus voltage. Screen and focus voltage controls can be seen on it. This component can be bought from most of the electronic spare part shops at your tow. The number printed on it is important and should be noted. The sample picture of that component is attached here. This component also known as Flyback transformer. OK.
You will need to replace the eeprom. The location is IC002. This is a common failure for this TV. There is the complicated way to find the part number. As there are three different eeproms available for this TV. So it depends which one we will need. You will have to note the numbers on the microprocessor (location# IC001) and Stereo Decoder, location IC1001). You will need a TV tech to install this. Or if you think you can give me the numbers asked and I will supply you with the correct eeprom. Read the numbers on the ICs, IC001 and IC1001. Thanks for asking and show all hands on deck!
To restore your television you will need to replace the eeprom. Let me tell you why! The stereo decoder and signal processor at one time were confused with the microprocessor. This corrupted the eeprom. Without the following information, repair is next to impossible. Fortunately the repair is near..so pay attention! Location of the eeprom is IC002 on the TV board. You will need to know the numbers on the IC 001 (the microprocessor) and the numbers on IC1001 (stereo decoder). This will determine which correct eeprom to replace. The reason I say this, is there are six different eeproms to choose from. Show this info to a TV tech if you cannot do this yourself. Thanks for asking and show a few a few hands of support.
hello, usually if the remot control is ok, then the infrared receptor need to be replaced, he is placed near the stand by light. in a rare case the problem is at the 5v voltage that goes to the receptor. more rare is the possibility that something is wrong at the microprocessor circuit. i hope it was helpful!! Let me know if you need further guidance
You have a corrupt eeprom. This is a case of mistaken identity.The eeprom is located on the TV board as IC002. Locations are labled next to each tv part. This eeprom [IC002] is dependent on which microprocessor [IC001] and which stereo decoder [IC1001] is used. There are three different eeproms, and you will need the correct one for your TV. Check the number on the actual IC . For example IC001 may be MCU A22V01-T0 and IC1001 might be MSP3440. If this is the case you will need eeprom part number [location IC002] 4835 310 57593. Philps/Magnavox parts have twelve numbers and that is the correct part number for this particular example. Thanks for asking and show your hands of support!
You have a bad eeprom. Very common problem for this TV. The replacement eeprom [location, IC002, on the Tv board] is dependent on which microprocessor [location, IC001, on the TV board] and which stereo decoder [IC 1001] are present on the board. See if IC002 has a color mark on it. red, yellow, green..etc. Or give me the numbers on the actual IC 001 and Ic1001. For example IC 001[ microprocessor] might beMCU A22V01-TO and IC 1001 [stereo decoder] MSP3440. Take this info to a TV tech if you cannot repair this TV yourself. Thanks for asking and give me a High Five of hands!
the problems due to the microprocessor on the remote reciever present inside the tv .i think the remote is normal working. as the only problem with your iinfra red reciever microprocessor.microcontroler circuit. Replace the IC to solve this. Check electrolytic capacitor coupled to the memory block of the micro processor. Contact service if you are not well verse doing all this rectification works. it is off high risk and caution thank you !
