BLOK MICRO CONTROLLER ( REPAIR )

Microcontroller is more commonly referred to as the IC program, it simply serves as the main controller as well as the interface / liaison between the users of the electronic products (eg television).In previous articles have discussed about the IC understands and knows the TV program, which consists of hardware and software part 1, part 2 Bus and Function Specific Pin / Port and section 3 Boot Up Sequence and Troubleshooting. While in part this writer just trying to supplement the articles mentioned above.Almost all current TV designs using IC program that does not separate the chroma IC, but has been integrated with the processor IC video-chrominance-deflection/jungle (VCD). Sorted from the ancestors and the manufacturer, so let's just LC863532B + LA76818A = LC76931 or TMP47Cxxx + + TA8690AN TC4052 = TMPA8823CPNGxxxx, quite reasonable as well.


Damages on the TV, among others, a TV device is sometimes (aka sometimes normal, sometimes not), OSD defective or missing, the key / remote is not working properly, the response is slow, can not save settings, the channel itself is slowly shifting (drift), disturbances in AV systems and video processors for failing to set (eg color or vertically out does not work), the TV is on hold with no response to the IC program, protected, white blank with no response and many other damage to the TV.Damages above could be caused by damage to the IC program, or could be just due to loose solder or only one resistor are delayed / end. This phenomenon is difficult to determine the location of damage in the process of repairing the TV, the IC program or other components of the problem.Because of this phenomenon, the workshop will inevitably have swerved in a method / way of improvement, not the same as when repairing the old school radio, old school black and white TV, or even an audio device as an old school old school-old school in fact is not equipped with an IC program in pengontrolannya . When reviewed,

HIS way
Once you can ensure that the IC program and memfonis damaged, it is time for hunting to the service center, service center when he got most of them can only gawk ....... spare part no stock is depleted, but the spare part is for the TV is still quite young, less than 3 years from date of production, what the manufacturers are deliberately a little kulak? or are still a lot of workshops to be fooled by the difficulty in droves to buy into the service center and once installed it has not cured the disease when the average price and the promise to customers is quite good 'scary'
