Dim get on just four second and before 2 transistor 5707 is broken and i replaced


Did the new transistors shorted out? You maut make sure to checkt the gray tuning caps in the inverter output sections, if they are bad, the inverter will run at the wrong frquency and burns uo the transistors. You also need to look real close at the solder joints in the inverter sections, especially around the inverter transformers.

I have a red and blue line to the left side of the screen is it got burned out bulbs


It sounds like your LCD panel TFT (Thin Film Transistors, each panel has millions of the transistor) driving circuits are failing, it will get worst with more lines appearing. New panel will be needed.

Dead pixel


Dead pixels cannot be fixed, each pixel is controlled by a transistor that is part of the LCD screen. If it is bad, the only option is to replace the LCD screen.

look at the 3 amp. fuse on the mainboard! By the way, you can buy very cheap USB light, wich are working with a small lighttube. Use the transistors of their generator!

Mother board Gigabyte transistor D0139 broken


This worry's me a little I have some ?'s that i need answered first before you started your cleaning did you ground your self and wait the 10 to 20 min time after you shut-off and unplug the computer before removing anything from the computer. If you did then before turning it back on did you make sure you replace everything in it right place. Sound to me like ram my have not been in all the way.

But it all comes down to one thing you need a new motherboard they really normaly don't make replacement parts for them and in the long run you don't know what else could be toasted.Most likely the bios chip went too.

Sounds like you have fried your output transistors. They can be replaced if u have the patience and know-how. Also check the resistors near the transistors. Some of them may need to b replaced too. I fu replace the transistors and the resisitors are still fried, u run the chance of burning up the new transistors again. I usually just replace both items since it's not that expensive and I'm doing the labor. What have you got 2 lose?
