The problem most likely is the P13USB chip on the motherboard of the switch and it will have to be changed. You can also check if you have a multimeter those 5 chokes near P13USB and the capacitors around it. Have you checked with another dock if you have a TV image?

Yeah I’ve tried another dock. How easy do you think it would be for a beginner to fix this or the price for someone to fix it?

With the right tools it should be pretty simple you just need flux a rework station of your choosing and the part and a multimeter to find the bad part

Hi Dear FXDX,

Today I changed a defective P13USB chip. The swtich completeley was dead, it was no any screen in hand held mode. Now working perfectly in hand held mode. But not working with dock, the dock is safer.

I checked the chokes in continuity mode and gives beep sound you sent picture another community.PI3USB

How can I measure the power of P13USB chip? I think it must be 3volt. Where will I place the probes to measure it, if you say me with the words I can’t understand, if you show me with a picture I can understand. Somethings difficult to understan for me. Thank you so much.

Now try and change M92T36 if you have a new one.

Measures pin 5-6 on the M92T36. Check to see if you have a short, on the usb D+ and D- lines.

Yes I have new one M92T36.

There is no short for the capacitors around the M92T36. I couldn’t really understand D+ and D- subject at all. How could I test it! Will I place one probe to D- or D+ and the other probe goes to 5 or 6th pin of the M92T36 ?

Remove the battery. Place one probe on pin a6 of the usb port, place the other probe on the top side of the common mode choke and isten to see if the meter beeps. Do the same for the a7 pin.
My advice if everything is ok with the measurements, change the M92T36

PS. Test all the capacitors around the charge chip.
