LG-21SL2RD Ultra Slim, Pincushion-Tr Hor. Panas !

LG Ultra Slim type 21SL2RD has a similar article describing type 21FU2RD and the same article from Tr Hor. Put me down!
In this second case, a new problem arises, which is PINCUSHION = Normal Raster To the right and right of the screen, the cursor moves inwards by 5 cm until Tr Hor is hot or Overheats, if the language is Tr Hor , it can be. lousy ... click on the pictures to see really damaged Malang!
Solution:
* In advance, I hope this service will be helpful for friends and family to understand the problem.
** LG includes K2xxx short FET clock type and 8 pin driver IC (click image to learn more) to test LV762xxx control IC for bearings and channels. Digitally via the data service menu!
*** Well, it is better to say that it is:
Open it and measure the Tr FET Kxxx first, if it is normal, remove the 8 pin motor IC and try to measure it with contact AVO Meter moeta Ohm, red wire on pin 6 and black wire on pin 8. there are plugs, the which means it is damaged ... All this is according to the previous photo, in this case my measurement results have a resistance value of about 80 kOhm! Because if the IC is normal, there is no obstacle, the nickname is infinite!
The IC number / type is KA393 (double comparator).
Good luck and good luck to all….
