Re: Panasonic TX-P37X10E problem with analog signal
Sorry i didn't reply earlier.
I tried with some settings in service mode, opt1,2,3, but without success.
Also tried to find software for this tv, but on Panasonic site i found only for 42" and above.
Could i use that software?
Is it possible to use component from old board, that contain software and witch one could be?
Do you know where i can find software for this model?
There is a picture of board in attachment....Leave a comment:

Panasonic TX-P37X10E problem with analog signal
This tv belongs to my friend.
One day it was dead and he took it to official repair service.
They told him that a-board is dead and asked around 300 euros for repair.
That was too much and after that, thanks to this site i found on ebay that board for 30 euros.
He replaced board and tv is working now, but there is a small problem.
Since a-board is bout in UK it is set for I standard and in my country is B/G standard.
Everything else is working except analog signal.
It founds about 15 channels only and without signal.
Service manual is attached.... -
Re: Acer AL1916WA dead update
Can You please tell me did You replace with same FETs and there markings.
On one fet I have 5 V and on another one 14.7 V on big tab. Are those values normal?...Leave a comment:

Re: Acer AL1916WA dead
Big cap is new one. Noise was before I replaced it and I thought it will help.
I tried to locate where is noise coming from, but I wasn't successful.
If it is LF100, how important is to replace it with another one, with same characteristics, or I can use one from some different power supply?Leave a comment:

Re: Acer AL1916WA dead
I have Viewsonic VA1916W with same power board.
Some of caps were bulged and I replaced all of them including big one.
Now there is some humming noise with power cable plugged in and power off.
When I turn on monitor there is no noise any more. It is working normally.
When it goes to sleep mode there is noise again. It is not loud but it is there.
What could be the reason of that noise.Leave a comment:

Re: No power Benq G922HDAL
I was pushing all the buttons and something strange happened.
After pressing 'menu' button monitor powered up!?
There was a message 'no cable connected'. After connecting vga cable there was a message 'no signal'.
After that monitor goes to sleep mode. I can awake it with enter, auto and menu button.
On pin with variable voltage after powering up there is 1.2V and pin below on picture there is 2V.
In sleep mode is vice versa, only 1.2V is now 0.8V.
I want to mention that is still 9 ohm between 3.3V and gnd.

Re: No power Benq G922HDAL
I checked cable for continuity and connectors are clean and on right way on their place.
Also power button looks fine. I checked it with beep sound and there was beep when I pres the button.
All resistors has good values on button board.
On picture of logic board I wrote values of voltages.
On third pin there is variation of voltage from 0.4-0.8V.
I assume that is on/off pin. Are those variations normal?
It looks like that pin is connected to transistor below that pin.
On other two pins is stable 5V.

Re: No power Benq G922HDAL
Can I try it with Fluke?
It gives 2,4V in diode test.
When I tried to test power leds with Fluke they turned on and fluke was on beep.
I don't know what voltage is applied in that case.Leave a comment:

Re: No power Benq G922HDAL
You are right about red and black wires.
I don't have external 3V power to apply.
Something else to check?Leave a comment:

Re: No power Benq G922HDAL
I also measured 16,7 V on testing points near connector for backlight on that boardLeave a comment:

Re: No power Benq G922HDAL
Yes, it is picture 3.
I tested it before: 0,8 ohm.Leave a comment:

Re: No power Benq G922HDAL
I made it to find voltage regulator and replaced bad one on power board.
I replaced it with lm3940imp-3.3. Now there is 3.3 V out of power board.
When I connected all boards and monitor to pc it won't work.
I measured voltages on connectors for other two boards:
CN701
pin1=3.28V
pin2=3.28V
pin3=5V
pin4=5V
pin5=0
pin6=0
pin7=0
pin8=0
pin9=0
pin10=0
CN702
pin1=16.76V
pin2=16.76V
pin3=0
pin4=0
pin5=0
pin6=0

Re: Belinea 101715 (help for identifying zener diode)
I was searching for service manual for this monitor and in this post [url]https://www.badcaps.net/forum/showthread.php?t=21185[/url] I saw that Viewsonic VE710b monitor has the same power supply board.
Does anyone have service manual for this monitor?

Hello,
I have Belinea monitor and it has same power board as Your monitor.
I need service manual for it.
Can You please tell me what is Your exact model of Viewsonic monitor VE710b. -

Re: No power Benq G922HDAL
I removed voltage regulator on logic board and it's not shorted.
Between 3.3 V pins and I pad is 0.9 ohms and 3.3 V pins and G pad is 8.8 ohms.
Other boards are detached.
Is this normal results or I have shorted logic board and it's time to give up on this monitor?Leave a comment:
