Hi all i'm currently looking at a Panasonic Viera TX-L42U3B with no dispay and just 14 blinking led flashes anyone got any ideas there's no other activity other than the standby light doing the flashes ?

My Panasonic Viera TX-P42S21B 42" 1080p HD Plasma developed a fault a few days ago.
It looks like it's going to come on, makes that click sound but then goes off. Doesn't turn on via remote.
So, obviously it's likely one or more of the components/boards. I don’t see any results for my model or a service manual anywhere, but I’ve briefly looked into it with similar models and apparently it is the SC and or SM board(s.)
How accurate are the fault blink codes? I don’t see any glaringly obvious damage on the SC/SM boards but the power supply has some markings.... -
Hi Badcaps,
I've had a friend discard a TH-65DX700Z Pansonic Viera Television and I've decided to have a go at repairing it. If possible could I please get some advice in terms of diagnosing the problem so I can purchase the appropriate parts for repair whether it be components, a repair kit or a replacement board. I am happy to post pictures if required.
TV Details:
Model # - TH-65DX700Z
Symptoms:
The television turns on and displays a picture then makes a clicking sound and turns off.
I haven't opened it up yet but... -
After watching some youtube videos and checking some forums, I'm at a loss. With both ribbon cables connected, we have no image. With the left one pulled out, the screen is black and white, split down the middle. With the right cable removed, it is all black. Backlight is working fine and we have sound and can open applications. We are strapped for money right now and are hoping to repair whatever the issue may be. I think the TV was manufactured in 2012, so I'm aware that may not be possible. Edit: Found a single vertical line of blue pixels on the left side of the screen with one of the ribbon... -
Hello, got a ST50 plasma TV for repair. No signs of life, not even blink codes. Opened it up to check the power supply, type MPF6914. Apparent issues from visual detection and measuring for shorts:
Diode type G972s6 - D101 with a short
Mosfet 06N90E - Q301 shorted
Fuse T5AH 250V - F103 blown
Diode D301 shorted
Relay DG1U-17VDC II - RL001 blown
I have not found a circuit diagram. Maybe someone here already dealt with a similar issue? Thanks for tips where else to check 😀... -
Hi,
the TV has a black screen. Sound OK, backlight OK.
When I measure T-CON voltages, there is VGL+VGH=0V. After unplug the right side of the screen from the T-con, voltages are OK and half screen works normally.
I tried to search for any kind of short on the right side, but I had no luck. I have a beginner experience in measuring and repairs of the LCD panels..
Thanks to anyone who can guide me in solving the problem.. and be patient with my english 🙂😁
