Types of LCD/LED TV Screen Problem
#basic
#Main
1) No Display (Grey Screen: you can feel that their backlight is lit)
This type of screen problem, you need to see their backlight is lit or not. If the
backlight lit but no display, then use the volt meter to check their T-con board
VCC supplies input voltage. If the Vcc has 12V or a similar voltage, that’s
mean the problem is on T-CON board or Panel. If the T-con VCC input voltage
missing, you need to trace it back to mainboard.
We can use the LCD/LED Panel Tester to checking their T-con + Panel are
working or not. So to confirm the problem is on Mainboard or Panel. Also we
can use the other two testers too.
2) Display Upside Down & Painting Display Problem
Normally this type of problem is causing by their setting in between Mainboard
and their T-con board. So the solution is to login to TV service mode
(Mainboard) to change their Panel setting. Or you can modify their T-con like
inside the LCD/LED Screen Panel Repair ebook. If cannot modify, then change
the T-con board to solve this problem.
3) White Display
Normally this type of problem is the T-con or Panel damage. If you use the
LVDS convert to VGA Tester, the TV Mainboard can output a perfect display
on its LCD screen there.
4) Display Slow Motion
Normally this type of problem is the T-con or Panel damage. If you use the
LVDS convert to VGA Tester, the TV Mainboard can output a perfect display
on its LCD screen there.
5) Display Double Images/ Jittering or Jumping
Normally this type of problem is the T-con or Panel damage. If you use the
LVDS convert to VGA Tester, the TV Mainboard can output a perfect display
on its LCD screen there.
6) Whole Screen of Vertical Colors Lines (Static or Dynamic)
Most of the time, this type of screen problem is causing by their T-con. If
you’re not sure, you can call out their TV OSD Menu. It is also same problem
too. If their OSD Menu can show a perfect image on the screen, that’s mean the
problem is in the Mainboard there.
Or just use the LCD Panel Tester to testing it, you will know the result directly.
7) Screen Display Divided to Several Section or Display Content Opposites
This type of problem is causing be their T-con board EEPROM firmware
abnormal.
8) One or Several Horizontal/Vertical Bar or Lines on Screen
Normally this type of problem is causing by their TV Panel.
9) Abnormal Display (Not mention the above)
This type of screen symptom, you can try call out their OSD Menu to see it is
normal or not. If OSD Menu normal, that’s mean the problem is on the
Mainboard. If still same problem, then you needs to use the LCD Panel Tester
or another two testers to testing this TV.
