Having problems with your Toshiba Satellite LP154W01 Notebook ?

CCFL OK but no display

\015 So, the screen no longer appears to work. I tried a new inverter, made no difference and it was suggesed on here that it would be the ccfl lamp. With nothing to loose, started stripping it down to change it. Out of curiosity I disconnected the video lead from the lcd leaving the inverter all connected up and powered it on. Lo and behold we had light, plenty of light, but if you connect the video lead back to the display it goes black, but the lamp is still lit. The external display still works fine...graphics card or lcd panel?\015

Answers :

As answered LCD panel. If the graphics GPU was bad you wouldn't get graphics on an external display.

[GPU. Graphics Processing Unit. It's an IC chip, which can be installed on a graphics adapter card, or soldered directly to the motherboard. If this is a Toshiba Satellite Pro P10 or P15 Series laptop, you have Integrated Graphics. A GPU soldered to the motherboard, and no graphics (Adapter) card.

By the way. The Inverter MUST match the LCD screen. Also vice-versa. If you purchase an LCD screen, make sure it is THE one you need.
