The ceramic 74alz74 and resistors may not be damaged. This should be done to see the tracks that pass under and to make a proper cleaning of the area. It has corrosion on the tracks and components. Use lemon juice to neutralize the acid from battery. Nov 18, 1, The same for the VC, how to find the correct value for the system to function properly. What is the maximum clock frequency to the flip flops? How to find the correct value for the VC between pF?

It is recommended to take a picture of the motherboard. Yes, my password is: I have a question. Nov 15, 7. Electrolytic capacitors, crystal and variable capacitors yellow and blue probably damaged and datasneet be changed. I found the solution. I need to replace the 74ALS74 but no stock.
