I have got an old Gardtec GT595 alarm which has got a faulty keypad with a failed LCD screen. This was apparently a very common problem with these and many people have had to replace the whole alarm because of this problem. Somebody claims to be able to repair the keypads by replacing the screen and I have tried it myself by replacing the LCD with a commonly available HD44780 1602 16x2 Serial LCD screen but it is not working. I am sure it is a problem with a driver or simular which is not allowing the screen to talk to the rest of the electronics. Does anyone know what this original screen was...

Apologies if this is in the wrong section but being a car alarm siren that makes noise i thought it be best to put it in the audio section.
Had weird alarm issues where siren made a strange noise: https://www.youtube.com/watch?v=ZjsqndhionU
took siren out of the car and checked it out and pics attached seem to be the source of the issue.
shockingly the alarm still makes its normal sound if i trigger it manually so speaker seems to be intact.
getting a replacement is gonna be next to impossible, its a Toad Ai606 which is no longer in production and cant see to find a replacement...

Good day to all. The bite alarm drains 9-volt Krona batteries. Current consumption when switched on is about 50 mA. I wiped the board from oxides, I will attach a photo (on the board there is a j3y transistor and a 7533 stabilizer, the microcircuit is erased = (the 3.3-volt stabilizer heats up weakly. I replaced it, nothing changed. I unsoldered the microcircuit, the consumption disappeared. The resistance on the pins of the unsoldered microcircuit from the point clockwise is more than 2 megaohms, the 11th leg is presumably ground. I warmed up the microcircuit, the consumption does not change....

Hello.
I am dealing with a Philips TV, 43pus7505 and is stuck on boot loop.
So I ordered a used CPU board, and now I have wired picture.
I think the problem lies in display option code. According to SM, the command for setting
display code is 062598 + MENU + 032 (032 is written on a label on back of a TV).
But as soon I press the menu button TV jumps in menu. Can someone please tell me what I am doing wrong,
or can I manually edit option code in SAM.​
