TL;NR ESP-07 module doesn't start

I bought a pair of ESP8266 07. One of them I soldered to the adapter plate, like this http://img.banggood.com/thumb/view/2014/xiemeijuan/06/SKU220333/SKU220333a.jpg.
There was:
- CH_PD pullup to VCC using 10kOm resistor
- GPIO15 pulldown to GND using 10kOm resistor
This module was warking correcly, but unfortunatly I broke it.

Second module I soldered to my own board:

Plate shcematic

PCB

- CH_PD pullup
- RESET pullup
- GPIO15 pulldown
Also there was convertion from 5v to 3.3v for UART (my USB<->UART module is 5v)
(so this pins are pulled up too)
- GPIO0
- RESET
- RX (not connected yet)

I build it, and my module don't start.
Red led ligting, but blue doesn't blink at start. No wifi spot. Nothing in terminal.
Module doesn't heating during work. Voltage is around 3.3v. Current is fixed to 6.88mA and it is very small, I think. (doesn't change at all).
Module has no reaction to reset.
I think, it can't start, but CH_PD pulled up.

Can anybody help me with this problem?
