Restart Issue Symptoms UA32K4000AR
When the customer brought this LED TV to me, I turned it on, and it turned on with its own unique sound, and then there was no picture on the screen; only its own menu display was showing. Even though there was no raster on the screen and the set was restarted repeatedly, due to the raster not being on the screen, I had a suspicion about its tuner, which later proved to be wrong because I disconnected it from the circuit board.
How to find the restart fault UA32K4000AR
Since this motherboard was not showing the raster on the display, the first thing I did was check its tuner. I took off its cover and observed it carefully. I found the tuner to be fine. Its tuner has IC MXL661. Anyway, I put the cover back on. Now I checked the voltage according to the circuit of this motherboard, and everything was correct here too, which means I didn’t find any hardware problems in it.
software related problem fix
Now I started thinking that this issue might be software related. This board had an eight-pin flash IC installed. Its chassis number is IC 601, and its number is 25Q64. I replaced this IC but first installed the bin file of the same model in it. If anyone wants this file, write it in the comment box. Anyway, after installing the new IC, I fitted the main board into the frame. I connected the power supply to it, and the fault was fixed.
