[size=140] Again with this TV which shows me the fault that the volume was fixed at full volume and does not change channels, I am checking the card where the buttons are and I found several open diodes. On the board have this enumeration D2233 zener diode, D2235 and D2236 zener diode, Someone will have the plan of this card to help me with the code of these diodes, they are not seen what code is to look for replacements.
