I have a few standby voltages that are 0, as seen in the picture. Is the Panasonic chip broken? In the picture I have all my voltages.

My Samsung UE75TU7020k lights up fine when one of the ribbon cables are disconnected from the main board, lights stay on but not getting half a picture, I do the same with the other ribbon and put the other one in and lights stay on but not getting half a picture. The standby light flashes 2 times then reboots then it then tries to come back on again and just keeps looping until I take either one of the ribbon tables out (doesn’t matter which one I take out it stays lit when either one is out). I’ve tested the backlights but all working with none shorting out, I’ve replaced the main board... -
Hi All,
Wanting to learn some electronics repair skills.
I found a non working Panasonic TC-P60S30 and this is my first project / attempt.
So far I have found a blown cap on the main power supply board.
After replacing it there's still no standby power.
Poked around and found a resistor on the PSUB power supply board that measures open.
An online resistor calculator shows this is a 93k ohm resister.
My questions:
Is that correct, 93k ohms?
Is it a fusible resistor?
Lastly, how do I know what wattage?... -
Hello!
I recently got an old VHS player from Panasonic and just for fun I want to try to repair this device. It is an AG-1000B portable VHS player from 1990 and it has a problem with picture quality in playback mode.
Picture in playback mode is very noisy and often loses sync but the still images are nearly perfect.
I want to know, is this something that could be solved by recapping or is the video head likely gone?
Also, what mechanism is this?
Any feedback is appreciated!...05-06-2024, 07:16 AM -
I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.
There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)...
