Pincushion distortion of LG 500G CRT monitor, which parts is responsable for this.


hi,
You have to check the pin control transistor in the horizontal section. It will be fitted on the same heatsik on which the horizontal output transistor is fitted.It will be a small transistor as compaired to the horizontal driver. Also you have to check the three mosfets in this section used to control the width.
ok

Screen horizondally pulled right side and screen rolled to left side


hi,
your monitors horizontal deflection side have some problem. you have to check the horizontal width cotrolling transistor mounded on the aluminum heatsik near the lot( line output transistor). also check the three mosfets which adjust the width for different resolutions. there are three such mosfets in the horizontal section.

fist of all replace the width controlling transistor in the heat sink. photo of mosfet and transistor is added for reference. not the exact number.

your irf 630 is not original purchase it from proper LG authorised service centre it is costly but never become faulty again duplicate mosfet overheats if your green led is on then measure voltage at E.H.T.connect meter at output transister if E.H.T. is producing then meter should show 1 digit if not then 50v will show take care that signal cable should be disconnected if E.H.T. is not producing then check +vcc at horizontal ic it should be 12v. if 12v is not present then check regulator ic 7812 insmps

INEED NO. OF OUTPUT HORIZONTAL LINE TRANSISTOR


If you mean 'flyback' or 'horizontal output transformer' and have the part number available, try one of the sources here:
Flyback links 
If you do not have the number you may have to search Viewsonic's website to loacte it.
Warning; the number of suppliers for CRT monitor parts is shrinking rapidly, my best supplier, ICM in California is long gone.
