A Skyworth 32 inch can be turned on every time for more than 20 minutes. This simple opening of the back cover shows that the power supply 5V capacitor and 12V capacitor are both pregnant and replaced with 0k.
The second 50-inch Hitachi plasma power-on indicator does not illuminate. Even the customers themselves checked the Internet, Hitachi's common buffer board was bad, and many repairs were done before. Just the same machine a while ago. I think that the cost of changing the buffer board is too high, and the chip replacement that I bought the buffer board was successful. Today decided to replace the chip again. After checking the two buffers, each block burned a chip. One of them also burned the board, but it was not particularly serious. Successfully replaced.
The third Konka LED32S3360CE. The customer said that it can be opened once and for all times. After checking the power supply, the indicator light is green, there is no sound, and the standby button does not respond. First thought that the common problem for the 6575 results in the power supply output voltage is normal, the power chip is not 6575 seems to be 6807A. Motherboard 12V 5V 2.4V3.3v and so on are normal. I feel some trouble. Finally, with a try attitude, backup 25Q32 data. Clear it again and then re-write the original data into it. Everything is normal and can be turned on at any time. Attach a bad chip diagram of the buffer board and a picture of the Konka board.
The appearance of the 8671A for Konka Power is the same as that of the 6755. I said above is that 6807A is a mistake, can not mislead the peers hereby to correct
