Hi,

I have a Toshiba A105-s101 I tried to reformat and reinstall with the recovery disc. The recovery disc software said it was complete and then the system restarted. Since it restarted I have not been able to get an image to come up on the screen at all. No boot screens or anything. I can not figure out what the problem is so far. Any help you can give would be greatly appreciated.

Summary of what’s already been shown in this thread: reports a blank screen after running the recovery disc with no BIOS text and no external-monitor output. suggested hardware isolation and ’s panel‑swap test (M35 panel on the A105 shows an image, A105 panel on the M35 also shows an image) is especially useful — it strongly argues the two LCD panels and their inverters are probably fine.

What that swap implies and where to look next: if both panels can be driven when connected to another machine, the fault most likely sits in the A105’s video delivery path (LVDS cable/connector, the GPU/display logic on the motherboard, or an early firmware/POST failure) rather than the LCD itself. A mis‑positioned picture on a swapped panel points to timing/pinout/twist differences between panels or a marginal LVDS signal rather than a healthy, fully compatible video output.

Practical diagnostic checklist (work only when power is removed; take anti‑static precautions):

  1. Power/POST indicators — note fan spin, HDD LED, caps lock/num lock LEDs. If the machine shows hard‑disk activity or fans spinning there is some boot activity; no activity increases the chance of a power‑rail or EC/BIOS failure.
  2. POST/beep test — if possible, remove memory to provoke POST beeps. Hearing expected beeps means the CPU/BIOS are at least starting and the video subsystem is the suspect; silence suggests a deeper board or firmware problem.
  3. Inspect and reseat the LVDS cable and hinge area — look for bent pins, torn foil, or crushed cable where it runs through the hinge. Reseat the connector on both the panel and mainboard.
  4. Visual board inspection — look for bulging or leaking capacitors, heat damage, or blown components around the power and GPU areas. Smell for burnt areas.
  5. If diagnostics point to the board/GPU: compare cost of a replacement A105 mainboard vs. professional reflow/reball service. Reflow is a temporary fix and not recommended for a long‑term solution.

If data matters, remove the hard drive before sending for service. The swap results from already narrow the field a lot — focus on the LVDS connector, power rails, and motherboard video logic next.

If you have an external monitor you might try hooking it up to see if you get an external display. Also you said nothing so I wonder if you get any BIOS screens or anything at all at at startup.

At startup I don't get any bios screens or anything either. I have tried to hook up a crt monitor and I get nothing. Running out of ideas ... lol. Thank you for your reply!

i have same problem (A105-s2719) , i tried to change lcd panel but nothing wrong with lcd panel . the problem was mainboard hmmm maybe lcd controler ...to be continued...

OK, at this point we can probably rule out the LCD as the primary cause of failure and the Inverter - the device that powers the high voltage lamp. The problem for both of you though is that the graphics card is integrated onto the motherboard in each of these models so you are essentially looking at a motherboard replacement.

Before assuming that try to remove all other components HD, Memory, Wireless Card, CD drive. All of these can be accessed from the bottom panel by undoing screws and pulling panels to get at then or just removing the retaining screw for the optical drive and pulling it out.

thanks for your quote:) ,actually the inverter is on but i cant see nothing (image) at all, im wondering with this case so i got another lcd on my toshiba M35 n i tried with this one... wow
the image appeared but the position was wrong :?:
then i tried to put a105 lcd on my M35 and the image appeared ! :idea:
