Re: Pavilion dv5 White Screen problem
Caps lock flashing is a video problem. I had one a while back and ended up replacing the motherboard. Spent way too much time trying to fix that one. You can always try and reflow the GPU and / or built on video ram. -

Re: Pavilion dv5 White Screen problem
It most likely is the GPU. I have had the same issue with a white screen on a DV5 with the AMD GPU and a reflow worked. I have also had no video with the caps lock flashing caused by a bad AMD processor. Be sure to test with a compatible CPU. Also make sure that you test the system on an external monitor with the LCD cable disconnected from the mainboard, to rule out a shorted cable.Comment

Re: Pavilion dv5 White Screen problem
DVx series shouldn't have GPU / South Bridge problems. Most common problems in these are Texas Instruments power management IC's. Believe me, I've tried GPU reflows that normally work on the older DVxxxx series all the time but have had zero luck on these new ones. That being said, the caps lock flashing is definitely an HP code for video malfunction. Like I said earlier - best not waste your time on this one.Comment

Re: Pavilion dv5 White Screen problem
If you figure the problem out is it really a waste of time from this thread I have gotten 2 things to look for or at on my Acer 5100 see if there are any similar Texas Instruments power management IC's that are bad and check to see if the video ram on board needs reflow dunno exact specifics...
I read somewhere that a bad connection on the back of your screen the cabling that actually connects to the to of the monitor on the back is plugged in crooked or not all the way can cause issues...
Keep at it let us know how your progress is coming this seems like a very common symptom amongst laptops not brand specific so if we iron this one out it would be a major feat!Please note: I am not responsible for any harm caused to you anything discussed is just discussion. Before you try anything discussed be sure that you have the appropriate knowledge and safety gear for the job. Like with anything education and safety are first! Do not try anything @ home without it.Comment

Hello,

I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -

As per subject, on power up display shows no image, but white
flickering screen. Strangely, it only happen after power was lost
when it was on. After power returns - white screen only, but if
disconnect power for 12-24 hrs, and connect then again monitor
works normally.
Any clues how to go about it would be greatly appreciated. -
I have an HP model : 14-cf0011nf and I want to change its display screen (it has an original 14" full HD TN 30 pins panel) which works without problem but I want to put another screen with an IPS panel, the problem is that I tried several screens but there is no display except with the original screen, I never had this problem before I changed hundreds without problems but this PC is not 'accepted than its original screen
otherwise on the motherboard it displays edp and I don't know, do the panels I tried only work with the LVDS protocol?
If anyone has any information on the subject... -
I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.
Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.
Then each time...
