Re: Panasonic tx 32lmd70 stuck in standby
Not powering on is unlikely to be resolved by a firmware update... for a start how will you update the firmware with no display? Have you done basic troubleshooting yet, like check P board output voltages?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search.

Hi everyone,
I've got a Samsung UEMU6199U which has no Standby LED and no reaction if try turning it on.
Voltages on the power supply board is okay. Backlight test is also okay.
I read about a corrupt firmware on IC1604 on some models, did a dump of this IC and turns out: First sectors are empty.
So I think my TV has exactly this issue.
Can someone please fix the dump?
And how do you do that?
As I understand you fill in the empty sectors and leave the rest as it is. But where do you get the "information" of what you... -
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?... -
After an update it stopped playing audio and video, I have reset it as it says in the manual and tried to reinstall the firmware over the internet but logging failed each time and I tried to download the firmware to install it by usb but it does not appear on the official page, could you help me? Since it would be a shame to have to get rid of him, European version Thank you very much
Best regards.

Hello to all friends of the forum and well found, here I am asking for your help and sorry for my translated English.
As per Hisense tv title LTDN50K220WSEU stuck in standby
PSU rsag.820.5687 HLL 4855WF
Main rsag 7.820.5842
I enclose the psu diagram, after the first routine checks I find myself with a regular standby voltage of 3.3v blue light on steady when the power button is pressed nothing happens, psu disassembled and bench checked ... forced ignition by sending a signal 3 , 3v on the SW and PWM2 pins the psu turns on and delivers all the voltages... -
I took an ebay gamble on an LG xboom pn5 speaker which was listed as having battery issues (turning on then off).
I got it earlier today and concluded it's in a demo mode because of the following:- When it's plugged in, it'll turn on and the power button will not turn it off
- Battery is healthy, reading 4.2v and not swollen, charges according to the xboom app
- the play/pause and volume buttons don't work
- You can pair to it and play music fine, as long as it's connected to power
- The bluetooth connection is disconnected after 5 seconds of audio pausing
- The DTS setting is defaulted
