Info:The Grillo Parlante Italian Version (originally called Speak & Spell) is an electronic game based on speech synthesis, produced by Texas Instruments since 1978 and no longer in production. The Italian version was distributed by Clementoni. It was designed for educational purposes, aimed at children, allowing them to learn spelling while having fun. The device is equipped with a membrane keyboard, an 8-character fluorescent display, a speaker, and a carrying handle.The Grillo Parlante offers several game modes: Write, Repeat, ABC, Code, and Guess, during which each letter typed and word spoken displays a corresponding character on the display. The Write & Repeat games have four levels of increasing difficulty. The Italian voice of the Grillo Parlante is by Luciano De Ambrosis.

TroubleShooting

Fixing a power supply  Grillo Parlante! The easiest fault to find is when it does not turn on, probably due to the incorrect connection of an external power supply.
Connect the battery or the external power supply 6 VDC 500 mA
Check with the tester that there are 6 volts between pins 3 (gnd) and 4 (vbat), this is the battery voltage.
Check that there is -17 volts between pins 3 (gnd) and 5 (display+speaker).
Check that there is -3,5 volts between pins 3 (gnd) and 6 (uC).

Without these last two values our Grillo Parlante will not work! Check and replace Q1 (2sb562 pnp)

 After many requests for repairs of Grillo Parlante, we had to set up a forklift to test the three chips that make up the game. I thought the pitch of the integrated circuits was 1.27mm, but no it's a little less than 1.25, so I had to take a strip with 1.27 gold-plated terminals, open it and use the individual terminals.in the second photo you can see the microcontroller on the socket. 

CD2702AN2 / TMC0270   Microcontroller / Display (The microcontroller is derived from the TMS1000 series and adopted to control both the keyboard, the display and to feed the speech synthesizer)
CD62190NL / TMC0350DNL Word Rom ( Italy )
CD2801NL / TMC0280NL      Speech Synthesizer

 Fix a membrane keyboard  Grillo Parlante! I hope with this last phase I can help all those who want to try repairing Jiminy Cricket. Often the failure to turn on is due to the membrane keyboard which has some closed keys. The new sticker is available to put in place of the old one.

 1) Remove the keyboard gently, as you can see it is not completely attached to the case, follow the edge of the keyboard.

2) Once the keyboard has been removed, clean the contact points of the case with isopropyl alcohol.

3) The same goes for cleaning with isopropyl alcohol.

 4) This is another type of keyboard but the same applies. Open it and clean with isopropyl alcohol.

 5) Insert the keyboard you removed holding it still, it would be better not to remove all the adhesive paper around it after cutting.

6) We have had new stickers printed to use in case the removed one is damaged or torn. Many Thnaks to Centro Stampa Salaria 

7) Work finished.
