The 21-inch sharp TV does not open like two inches at the top. I want to do it through resistance but I don't know which ones. Please help.

hello buddy: if you have lc501-AN552 as vertical lc- change the R503 of 2.7ohm x an R of 2.2ohm ... it also measures what tension you have on pin2y6 of the vertical lc ... also measures what tension you have in pin4 of the vertical lc ... comment if it worked for you .... greetings !!!

I tell you, my friend, that the tensions are ok according to the diagram. Change the resistance that I suggested and wala everything is fine, the line disappeared, the screen is complete. Thank you very much, I appreciate it. Greetings from Nicaragua.

Good afternoon, the reason that this resistance is burned, what is it? Normally they are the electrolytic filters of the line that feeds this integrated, if you have not changed them you can see that the resistance in question is heated, unless the replacement is more watts, which should not be done, for the protection of the ( CI) integrated the most valuable component for your pocket. Best regards from, Spain.

Diagram here: https://elektrotanya.com/sharp_ga1_chassis_14lk14.pdf/download.html First check the good condition of the electrolytic capacitors in the vertical stage, even at the source that feeds the vertical IC
