What model of tv we are talking of? Where do you got the chip? Is probably a fake , scrached surface.. try a different source an don't get the cheapest..

tv model is sharp lc-60le635 e.
the last chips i ordered by a regular shop, thi first one on ebay or ali.
is the chip suposed to deliver voltage to transformer pins 1-4?

idd replaced the diode with ann original.
my electronics knowledge is a little poor so i guess that the te transformer have to deliver some voltage to pin 5 on the chip. but there is none!
or should the cip deliver voltage to the transformer?
on pins 2 and 3 i have normal voltage. on 1-4 none. when icheck with multimeter pins 1 and 4 have continuity.

Have you read the datasheet on the ic? Read page 14 Startup Operation. it explains how the IC produces the startup vcc voltage.

What do you mean for "regular shop"?

where can i order good ones?

First the professional channels, RS components, Distrelec, Conrad, Farnell, TME, Digikey, Mouser.. if there isn't you can watch some ebay shops specialized in IC and with a lot of good sells, UK, France usually is OK

I replaced the ic several times from different sellers. Unfortunaly nothing worked. Also ill tried all the tips you guys provided me. And iam greatfull for that.
This morning i walked into my shack, and the screen was cracked thanks to one of my kiddos.
So the case is close now.
