Re: toshiba c850 back light problem
Is schematic available?? M/B code?? If avlbl, then post the schematic here and do the basic homework like measuring voltage on lvds pins and report here. -

But you didnt reported any measurement??Comment

Re: toshiba c850 back light problem
Refer to page 34 of schematic and check voltage on pin 21/22/23/24/25 & Pin 1/2/3/4/5 and post here if you are not willing to measure all pins.Comment

Re: toshiba c850 back light problem
I doubt your measurements. Pin 1 &2 are connected together and can be 19V but pin4 cant be 19v. Are you aware how the pins are numbered on lvds connector-Its not serialwise. Pin1 on this side and pin2 on the opposite other side. Re check once again.Comment

This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors
I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using
I am comparing them to a brand new one that I installed
The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well
I going to let it run for several days before I remount back on the wall next to the... -

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hello Guys,
I received Toshiba Qosmio X755 that has a charging problem and I'm stuck trying to figure out the problem.
- When battery is unplugged i works without any problem.
- When I plug in the battery after plugging in the charger, it works correctly and the battery is charging.
- When I plug in the charger after inserting the battery, it stops working. ( voltage dropped and consumed 8A, reaching the maximum capacity of my bench power supply for 5 seconds, and stop working after )
Can you help me diagnose the problem? I have attached...
