Only the story of Changhong TV 2588! Changhong Color TV 2588 is a Toshiba two-chip machine that won a gold medal when it was first introduced. However, due to the cumbersome structure and high failure rate, there are often some odd-shaped faults that make it difficult for the repairman to solve. I recently encountered a Changhong 2588K machine with sound, characters, but no light, AV has a blue screen, can put VCD, shaking the bottom plate will sometimes be good, initially considered to be a virtual weld, but the front repairman has been welded over and over, it seems It was impeccable, so I carefully observed it with a magnifying glass and found that the P6 (VIDO OUT) on the wiring post of the TA7680 board was loosened by two wires outside the TA7698 38. The root solution was solved. This connection line is not available on other machines and is not marked on the local circuit diagram. Therefore, only Changhong 2588 color TV has this fault.

I remember that I remembered another malfunction of this machine on the map eight years ago. I am laughing for it all the time. There are blue screens on TV, no pictures, sounds and characters. The result is that the C30 (1UF/50V) electrolytic capacitor on the middle panel fails, and the parallel resistance 560K becomes larger. I remember that I have spent several sleepless nights to solve this problem!
