Hot = a short. Find and relieve the short. Beeping means a line is down at LCD

Connector find missing voltage, it is probably on the shorted line

Start by finding what is short to ground that shouldn't be. Compare to schematic. Start at LCD connector and work backwards using schematic

But i am facing with new problem :( my touch now work. i changed few screens and nothing , checked all component again, clean the connector and still not work??? what that can be? can you tell me some solution ??? i am very grateful with your help thanks alot :D

Same thing--work backwards from touch connector and look for missing voltages. Touch rails are something like SAGE_5v7 and neg 5v7

da

do i need to check rails with connected battery or disconected battery, or on or off phone ??

Same thing happened when my phone screen broken. It beeped because there was no signal from lcd. Try with new screen, and check the lcd + digitizer connection on your phone clean it with alcohol.
