Sweltering weather, annoying heat. When I was slumbering in the afternoon, the phone of the aunt woke me up: a TV set made him breathless, please help me save my life!
Very reluctant to get up, ask the address, drive to the fire. Hahaha! It turned out that his brother's nephew had a TCL2988DB color TV broken. Because it is a relative relationship, no matter how poisonous the outside sun is, it must be done immediately - who does not know that the Shenzhen Universiade is in a fierce competition?
Fault phenomenon: three no.
Apprentice overhaul process: Find out that the fuse is burnt, the power switch thick film IC801 (S6708A) is short-circuited, and after 15 minutes of replacement, it will break down again! Suspected that the new parts are under pressure and power, and replaced with the disassembled parts, still the results, check the periphery for no abnormalities, interrupted ideas, and rushed for help!
My solution process: first download the circuit diagram online, carefully read it again, slap the ball to the apprentice's back, decisively asked him to remove the C812 (220UF/16V), using the pointer table to detect, almost no signs of charging and discharging and leakage is very big! Command to replace the capacitor, re-install the power switch thick film, replace the fuse, boot, OK! The apprentice grievance said: "I also doubt this capacitor, but the shell is very good, there is no shell up. So..." "So, it is because of your care that I let the sun shine!"
Just laughed, beer...
This fault reminds everyone - sometimes do not think that the capacitor is not good, the shell will change, you do not know how to remove it!
Show the night, I hope you like it. Thank you! !
