How i can solve the problems ?

Look for "HV flip" into service menu (or turn TV by 180° )

you have to change HV Flip to opposite value. If it is on, set it to Off and vice versa. Be careful in service menu, you have to navigate only with rc keys up/down, and any "left/right" will change values! Take screenshots of sm before to do anything.

In my service menu there is not hv flip menu!!! There is a way ti activate this menu???

If you're sure you checked everywhere, then possible you have to unlock "extended" service menu for option to be shown. Check wiki for how-to, or search "extended service menu" on forum.

@zoelechat possible you have some libFactory dumps from same TV somewhere? Can you check?

Well, I've got only the few (despite easiness) dumps from libFactory thread... But anyway, HV flip option is not amongst "special items" libFactory accesses/log.

I have send factory + 3speed with ruSamsungTVCommunicator . how i can check if i have activate extended menu?

ruSamsungTVCommunicator method doesn't work anymore from very early E fw, only possible method is IR.

Only Need ti install app and send s1 s2 s3 ?
