Elitebook 8560p - no display + external monitor image when booting

[DanApostol]

EliteBook 8560p, Product number: LG736EA#ABB, out of warranty.

I had 2-3 times in the past year when the behaviour was the same but it dissapeard after couple of minutes/hours.

In this morning again:

- when booting everything works well (i can hear Windows starting sound) but no image is displayed on laptop display or even on HDMI TV ('No signal' is displayed on TV, it worked well previously).

I tried some suggestions like taking out the battery + pressing power button for 30 seconds for hard reset => no luck.

I can wait to see if it will work in the evening, but until then I need some advices:

- could it be from a failed inverter?

- other possibilities besides inverter?

- what's the part number for the display inverter ? link? I cannot find it on http://partsurfer.hp.com....LG736EA but maybe my eyes were foggy 🙂

- I have some assambling/desassambling experience, I assume I can DIY the inverter replacement, right? 🙂

Any ideas are welcomed 🙂

Thanks in regards.

Hello D.

- No video in Internal and external display

- Unit boot

It Doesn't look to be an issue with the display

It Doesn't look to be an issue with the RAM failure

It Doesn't look to be an issue with the inverter

- UMA Video card?

Possible CPU (with GPU) or system board failure

- Video card Discrete?

- Possible Video card or system board failure

Hello and thanks for your reply.

I'm on a Ati Radeon 6470M, can I investigate myself and find that video card or system board is broken or should I get my laptop to a service center?

Thanks again.

Hello

computing is not a exact science 🙂

You have experience of course! But it's suppose that Service Center have more resources (parts to crosscheck).

The best solution in my opinion is the best solution.

Of course will be better ask for a quote.
