TV Sharp LC-49CFE6242E - not working - 2
I wrote a topic earlier for this TV...[url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-tvs-and-video-sources/3487984-tv-sharp-lc-49cfe6242e-not-working[/url]
I managed to fix the power supply but there are still some faults. The sound works a little and then doesn't work a little and the tv doesn't respond to the remote control at all (I've tried several remotes).
I suspect the motherboard...is there anything that can be fixed or does it need to be replaced?https://I wrote a topic earlier for ...-working[/url] -
I managed to get this TV working, there were several defective capacitors in the power supply.
Now another problem is happening, when working it happens that the sound is interrupted. Most of the time it works ok, but it happens that there is no sound for a few seconds or a few tens of seconds...
What could it be?Leave a comment:

TV Sharp LC-49CFE6242E - not working
Hello,
I get one old TV, Sharp LC-49CFE6242E which is not working.
When turning on the TV, the inscription SHARP is displayed on the screen and after a few seconds the TV turns off.
So far I haven't found what voltages should be at the output of the power supply and I haven't made any measurements.
If anyone has any ideas, please let me know.Starts10-19-2024Ends11-19-2024 -
Re: TV Philips 40PFT4101/12 - power on loop
I don`t think that LED is bad, it is just a quick flash and then it lights up for 15-20 secunds and then TV restarts.Leave a comment:

TV Philips 40PFT4101/12 - power on loop
TV is Philips 40PFT4101/12, power supply 715G6934-P01-000-002M, motherboard 715G6947-M002-000-004Y (703TQGPL068).
The problem is that when it is plugged in, the TV turns on by itself, the Philips sign appears, the backlight turns on and off a couple of times, and the TV turns off, and so it repeats itself in a circle. It does not respond to the remote and nothing is written on the screen, the red light does not blink.
A few weeks ago, it used to turn on by itself about once a week, but after that it worked, now it doesn't work.
I checked the power supply, voltages are fine,... -
Re: Grundig 49 VLE 420 BN - no picture
The TV is still not working, I haven't dealt with it for a while.
I read that it is possible to cut some lines that go to the screen, that way you can "wake up" the transistors and get VGH and VGL again. Does anyone know exactly which lines need to be cut on this TV if this is correct?Leave a comment:

Re: TV Philips 43PUS8505/12 - horizontal line and picture jumping

thanks for the advice......Leave a comment:

Re: TV Philips 43PUS8505/12 - horizontal line and picture jumping
I replaced T-CON board and problem is remained.
Then I noticed that D007 is very hot when tv is working, so hot that you can`t keep touch it with the finger.
When I disconnect cable from T-CON board to the panel board on this side the rest of the picture is ok with no interaptions.
When I disconect cable on other side the problem is remaining.
So it look like D0007 on panel board on ane side is bad. I can`t find any shorted element with multimeter.
Is there any repair possible or...Leave a comment:

TV Philips 43PUS8505/12 - horizontal line and picture jumping
TV is Philips 43PUS8505/12, bought in 12/2020, so the two-year warranty has expired about 5 mounth ago...
Problem is that 15 minutes after TV is turned on, the horizontal lines appear and picture start jumping up and down.
I suspect that T-CON is faulty when wormed up...
I separated all the cables from the T-CON and cleaned them but there is no change.
Eco mode is disabled, software is up to date, I make factory reset and reinstal TV from TV menu...no change, problem is stil here.
Anibody have some thoughts?... -
Re: Grundig 49 VLE 420 BN - no picture
I finaly got tv with broken screen which have picture, first i put my old motherboard in that tv and it has pictures which means my motherboard is working.
After that, I put the motherboard from that TV into my TV and there is no picture, only a line at the bottom of the screen, as before, which means that the screen is not working, i.e. some element on the screen panel is not working....
I will try to look into it (I already did it earlier).
Are there any reference voltages that need to be checked and how to determine if...Leave a comment:

Re: Grundig 49 VLE 420 BN - no picture
I tried all panel files with no success.
Now I wonder is that other motherboard correct or is it faulty or just with incorect panel file because I don`t have feeling that update is running.
USB is just lightning not flushing for minute or two and than it turn off.
I tried to sign up for Aswo but did`t receive response so far.Leave a comment:

Re: Grundig 49 VLE 420 BN - no picture
I tried it with no result.
I push P+ and turn TV on power, backlight turn on, if I keep holding P+ down, screen turn off and then turn on again.
When I release P+ screen turn off, blue led keep blinking and nothing hapened for few minutes.
Then I turn off the power and turn it on again just blue led blinking all the time, the screen does not turn on....Leave a comment:
