I just bought a used PS3 for 50 bucks that for the most part refuses to display any video. When I do get it to display the video it's mostly garbled and then the system freezes. I'll have to turn it upside down to temporary fix it. I'm tempted to attempt a heatgun reflow, or try baking the motherboard in the oven at 390 C. Anyone have any success stories or any tips they'd like to share on this repair?

Re: PS3 Gpu problem
I would not recommend you bake the board in an oven. Too many things that can go wrong. At the very least, there's components on both sides of the board, so some of them may fall out. Plastic on the connectors may melt as well.
Besides, there's plenty of cheap heat guns that will do the job. I got mine pretty cheap from Micro Center (it's this one).
You will also need flux, preferably the no-clean type since you will be putting in under the CPU and GPU before the reflow.
Remove any thermal compound from the CPU and GPU before the reflow and put new one afterwards.
By the way, can you post a picture of the blue-ray ribbon connector on the main board? I just did a PS3 reflow last month, but was unsuccessful. I suspect the "tech" who reflowed it before me screwed up something, including the blue-ray connector (which looked damaged), but I'd like to confirm this. Thanks.Last edited by momaka; 11-20-2010, 12:30 AM. -
Re: PS3 Gpu problem
390C is too much. I always went with 210C over 7 minutes when i was using the oven. And no i never had any stuff fall out tho i did melt some plastic parts on an Asrock motherboard - that was because the oven's thermostat broke without me knowing it. Since then i've used my multimeter's temperature probe to monitor things.
Anyway before you try any reflow method please remove everything you can from the board, and see if the board is flat. If it's bowed forget about it. I had a Gigabyte AMD board that completely failed when i tried to reflow it because they used a plastic CPU backplate and over time the board bowed hard enough to damage the soldering. When i cranked the heat up on my hot air gun, i heard cracking noises. That was the chipset unsoldering itself completely because the board was so bowed.
Also if you want a reflow to last apply liquid flux prior to reflow and make sure the heatsink goes on real tight afterwards.A working TV? How boring!Originally posted by PeteS in CAComment

Re: PS3 Gpu problem
So in the case of something like an nVidia 8800GTS, I should have attempted to get some flux under the chip first, right? If it fails again, i'll do that.Originally posted by Th3_uN1Qu3Comment

Re: PS3 Gpu problem
Here are some pictures. The first picture is of the bluray cable and the next is the aftermath of the heatgun. I bought some liquid solder flux from microcenter... but it looks messy as hell... I'm hoping I got the right type. I blasted the gpu at around 220 and 240 C for 10 minutes. I noticed the board was kinda warping so I used some bolts and washers to try to keep it in palace. This is the 3rd time I've done this. The other two unsuccessful attempts I blasted it for around 5 minutes. If this doesn't work I'm probably going to sell it for parts.Attached FilesComment

Re: PS3 Gpu problem
Wow, yours too? I reflowed mine twice, but nothing changed for me as well (was still getting YLOD).
Are you at least still getting the same problem or is your PS3 totally dead now? Or do you have the Yellow Light of Death (YLOD)?
I'm not sure if 210C will be enough since the PS3 uses lead-free solder as far as I know.Originally posted by Th3_uN1Qu3
I think Micro Center only had one type. Got mine from there as well. It was the $10, 100ml one from MG Chemicals. Came in a black bottle. If you have the same one, it should be right.
Doubt the warping was caused from the heat because I reflowed mine twice, with the second time at over 400C. No warping or damage to the board whatsoever. Did you pre-heat your board? If not, peraps this could have cause the issue.Comment

Re: PS3 Gpu problem
ylod can also be caused by the psu (not many caps in them, but not the best either)
or a bad drive.Comment

Re: PS3 Gpu problem
I'm getting ready to reflow one someone gave me to see if I could fix. Thank you all for the tips. I'll be back to let you know how it worked!Comment

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hi guys, I have a Dyson v15 that didn’t work. The battery blink 10 times. If i disconnect the cable of the dust detector board, the Dyson turn on but after some seconds stop because didn’t feel the flow of the air because I disconnected the bird sensor, if I connect the Dyson is death. I notice the big mosfet I think with 3 pins. If I check the mosfet I have a short circuit from the center pin ne the left pins…so I think that s the problem or I wrong? The problem I can’t understand what type of mosfet is….someone can help it s hard to find. New board... -
Hi there!
I have a Sony Bravia KDL-40Z4500 which shows a colored vertical stripes pattern when turning on, with a central black shadow that slowly dissipates within the first 10 seconds.
Photo of the situation after the black shadow dissipates:
After this behavior the red LED will blink 9 times, then pause for a bit, and blink again 9 times, in a loop.
I checked the manual (available here) and this corresponds to "HFR error", quoting from the manual:
> This indicates HFR Communication error. [ HFR Communication... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
Assuming...
