When the power is turned on, a snapshot appears on the screen and it turns off. 2 red LEDs are flashing.
I disconnected the power module cable going to the main board. I threw a power on jumper with 3.3 v from outside. The relay is working and there is 12v and other voltages in the power socket.
Where else should I look? All fuses appear to be intact. -
Hi everyone,
I'm new here and trying to repair my Panasonic TX-P50V10E plasma TV, which is currently showing the 6 red blink error code.
Just for context: I'm used to building PCs and installing modchips in old consoles, but this is my first time trying to fix a TV. I'm French, and while my English is okay, I'm using ChatGPT to help translate and clarify my messages as much as possible — so please forgive any odd phrasing.
I'm also not very experienced with using a multimeter, but I'm very motivated and ready to follow instructions carefully and report... -
Hello again everyone,
This is my latest mission, to try getting this Sony tv back to normal working order…
I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried... -
So I got this Sony and purchased it working.. got it home and it was 4 blinks red. Seller actually refunded me thankfully. Now it's massive to take apart and I know 4 blink can be the panel sometimes but not always..
But I found a method through other ways with grounding out the bl error pin on the LD driver board. Now the tv turns on and works.
Pin is number 27. It was either remove the resistor right next to the solder pad or solder the pad to ground. I soldered the pad.
Now what is this going to do to the tv? Is it just going to die shortly down the road?... -
I have a strange fault on a Sony amplifier. The volume control varies the display from MIN, then 1 up to 30 and then MAX as expected. At MIN there is no sound. However, at 1 it is quite loud and increasing above 1 does not change the sound level.
I have tried a Cold Reset as per the service manual.
I have looked at the I2C clock and data to volume control chip IC501 (BD3499FV). Data is only sent to IC501 when the volume is set to MIN or 1. At any other setting no data is sent to IC501.
I have looked all the way through the service manual and tried many online...
