Re: Acer AL1706AB no power

Thanks for the quick reply, I'll search around for a replacement logic board, but probably just shelf it until someone brings one in for the parts bin.

Re: Acer AL1706AB no power

Hi, thanks for the reply, I was thinking the source would be the ps board because my brown wire is 0v where in [url]https://www.badcaps.net/forum/showpost.php?p=86701&postcount=6[/url] RobertoIsRad's was 4.5v. I tested again last night (2am) and while testing I flipped the power button board away from the panel buttons to see it better. When I first plug in the ac, I get a very faint amber light for a few seconds, and while testing, I gathered readings for : u702- top- 4.28v, middle-3.24v, bottom-0.01v q701-left-0.71v, right-0.01v q702-left-3.27v,...

Hello, I have an al1706ab that had died the other day, no power, no lights, but the vpu on the logic board gets hot very fast. Using similar threads as a guide, I tried bypassing u406, no change. The big cap is showing 165v, cn302 connector is showing black= 0v, brown=0v, red=14.39v, orange=0v, yellow=4.94v, blue=0v and purple=0v (from top to bottom). I'm not sure where to check next, and thanks in advance for any help, its greatly appreciated....

Re: hp l1950 shuts off after 20 minutes

Hi, sorry for the long delay, holidays and work put this project on hold, but I got a few free minutes the other night to retest the hp. I'm in Canada, 110v mains. with an old Philips 17" panel connected, the lamps stayed lit, so I retested connecting the hp lamps on at a time, and discovered the bottom plug for one of the lamps (pink wires) is the culprit. If I run two plugs from the Philips and 2 from the hp (blue wires) it'll run for hours, albeit dimly. Is there any way to bypass the bad lamp and run the panel on just the other 2...

Re: hp l1950 shuts off after 20 minutes

As an update, I just tried the lcd panel plugged into another power board, the backlights stayed lit, and the ther board's panel in this hp, the same standby issue.

Hello, I have a few monitors here that have issues beyond bad caps, which through searching the forums I haven't been able to sort out, so, as a learning experience, I've decided to tackle them. The first is an HP L1950, which goes into standby after about 20 min, a few clicks on the power switch usually gets it to turn back on for a couple more minutes. No visibly bad caps, and I didn't notice any bad solder joints. f901 showed 1.3a, f903 showed 1.6a, but I'll retest those two fuses again, if needed....
