Re: baird 42 no picture
Do you have the following voltages:-
Con4
Pins 3, 4 = 5V
Pin 5 = Power _On
Pin6 = 5Vstb
Pins 12 & 13 = 12V
Con3 & Con 5 = 24VWilling to help but I'm no expert.Comment

Re: baird 42 no picture
Sorry bud,Im a amateur,So these have to be tested again with unit on or standbyComment

Re: baird 42 no picture
Test with unit on standby and give the voltages on those pins and then out of standby giving the pin voltages again.Willing to help but I'm no expert.Comment

Re: baird 42 no picture
con4 only has 4 pins or am i reading it wrongComment

Re: baird 42 no picture
Can you post a well focused photo of the edge connectors and any printed labels alongside them.

Re: baird 42 no picture
So alongside each connector pin there's a legend.
Can you measure the voltage on each wire and compare it to what is written alongside
Example
Legend Name = Reading
GND = 0V
+5V = xxxxV
5VSBY = xxxxV
12V = xxxxV
24V = xxxxxV
etcLast edited by dick_barton; 02-16-2017, 09:18 AM.Willing to help but I'm no expert.Comment

Re: baird 42 no picture
yes can do,before i start do i set dc to 200 ? as reading higher than 20v on multi,ground the black and read from the red,placed inside connector with connecting block still connected,if you understnad what im talking about,
does the tv set have to be switch on or standby ?Comment

Re: baird 42 no picture
You can set your meter to 200V dc if you want to. Place the black meter lead on metal panel and the red lead to connector pins.
Again do the check in standby and then out of standby.Last edited by dick_barton; 02-16-2017, 09:29 AM.Willing to help but I'm no expert.Comment

Re: baird 42 no picture
me neither,so its dropped voltage,how do i know what powers this pinComment

Re: baird 42 no picture
Is there a cable at that location and are you are saying it reads 1.9V and not 5V which is written alongside? Where does the cable go? The power supply provides power to other circuit boards so it's an normally an output not an input.Last edited by dick_barton; 02-16-2017, 10:12 AM.Willing to help but I'm no expert.Comment

Re: baird 42 no picture
selected 20v on multi,the 5v are reading 5v the 'stb is 2.01,Comment

Re: baird 42 no picture
So it now looks as though you have all the voltages and power to the backlights and Tcon board.
I don't know what else to suggest. It may be an EEPROM problem which are available from:-

But perhaps better to wait to see what others on the forum suggest.

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)... -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started βfading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly βnew' Tcon board this time, and... -
Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,...
