Re: Gateway FPD1976w / LE1936 Problem
I just tested it with a setting on the multimeter reading up to 200 ohms. The reading I got was 2.2 consistently, I tried it multiple times. I assume this shouldn't happen. Would that mean its blown?Comment

Re: Gateway FPD1976w / LE1936 Problem
What ohm reading do you get when you touch the two leads together?Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

Re: Gateway FPD1976w / LE1936 Problem
Touch your two probes together. If the reading is more than 1.0 ohms, look at replacing the battery. Or trying cleaning and reseating your probes (jack and tips).
You would be the 4th or 5th person in the last 10 days on this board that might have a bad battery in the multimeter.--- begin sig file ---

Re: Gateway FPD1976w / LE1936 Problem
Alright well I tested the probes together and got a reading of 2.5 Ohms. I replaced it with a brand new battery and tested the probes again and got a reading of 0.6 Ohms. I then tested the fuse again on the logic board and got a reading of 0.6 Ohms. I guess since there was no change in resistance that means the fuse is blown. Am I right?Comment

Re: Gateway FPD1976w / LE1936 Problem
Your fuse is a good.
The reason for having a fresh battery is to get accurate readings. Many of us here say that a good fuse measures less than 1.0 ohms. If we didn't know you had a weak/bad battery, we would incorrectly tell you that your fuse is bad (> 1.0 ohms).
Also, many voltage regulators on the logic card have a +/- 1% tolerance rating. If your multimeter is inaccurate due to a weak/bad battery, we would incorrectly assume that your voltage regulators are bad.Last edited by retiredcaps; 12-27-2010, 01:33 AM.--- begin sig file ---

Well if its not the fuse then what else could it possibly be?Comment

Re: Gateway FPD1976w / LE1936 Problem
In your logic board photo, you have 2 voltage regulators in the top left hand corner. The part number might look like AL1117-33 indicating a 3.3V DC output. AL1117-18 would indicate 1.8V DC output.
You can try measuring these 2 voltage regulators to see if they are good or bad.--- begin sig file ---

I'm sorry but I am not seeing anything labeled AL1117-XX on the board.Comment

Re: Gateway FPD1976w / LE1936 Problem
Normally, I would give people PCB board designations like see U1 or U4, but your pictures are so blurry and out of focus, I can only guess at the part number. I circled (in yellow) the 2 voltage regulators in your pic.Attached Files--- begin sig file ---

For both components I received a reading of 1.8 volts.Comment

Re: Gateway FPD1976w / LE1936 Problem
Actually, on the regulators themselves, one says AS1117L-18 and the other AS1117L-33. I suppose the one reading AS1117L-33 is bad because I received a voltage reading of 1.8 volts?Comment

Re: Gateway FPD1976w / LE1936 Problem
That is what I figured so I assume this one is bad?Comment

Re: Gateway FPD1976w / LE1936 Problem
Either the regulator is bad, or the load is excessive. CAREFULLY check the temperature of the regulator. If it is blistering hot the problem is probably excessive load. If cool, it definitely is bad.

Actually, I do not know which is input and which is output so the picture is of the voltages I receive (+1 resembles the positive probe is on the prong labeled 1, -2 resembles the negative probe is on the middle prong not labeled etc.)Attached FilesComment

Put your black probe on a ground screw. Put your red probe on pins 1, 2, and 3. Report all voltages.--- begin sig file ---

I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down

i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double... -

Good morning,
I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise.... -
Full name/ Model: Asus Zephyrus M16 / GU603ZW-M16.I93070T
CPU: Core i9-12900H
Onboard 8GB DDR5 4xMT60B1G16HC-48B:A
Problem: This laptop was brought to the shop with the board already meddled with. Last technician (maybe without the right tools) removed an electrolytic capacitor (PCE9203) sensing resistor (PRS9801) and probably flashed both BIOS (U2802) and VBIOS(U7802).
The laptop's behavior is: When connected, it tries to power up. CPU powers on, and (allegedly) the power sequence finishes and goes to S0 (PLT_RST = 3.3V). It consumes 600mA, ramps up to 1.100 A and...
