Re: 2011 Sansui HDLCD4050B 40" LCD CEK649A Power Supply Troubleshooting
Finally got the tuner figured out. I could have saved a lot of time if I had the remote. I turned the TV off so many times trying to scroll. Not a bad picture though watching this guy makes me want to break it again. Thanks again for all the help! Onto the next one.

That standby power supply is running 24/7 even the TV is turned off so it is exposed to spikes and surges, part itself can also just breakdown.Never stop learning

Hello from France,
mon2 kindly advised me to post a thread to ask the question(s) I'm concerned about. I'm new to the forum and I'm looking for practical courses for troubleshooting pc motherboards especially laptops in Europe, if possible in France. I have been a computer network system administrator and a corrector of administration modules for automated programs under Unix. But I really miss the practical "ops" side of troubleshooting. So I would like to start from the beginning: 1.8V, 3.3V, 5V and 19V tests for example, etc...
Do you think this is feasible for me? I... -
hello friends, I have a DELL LATITUDE 5420---MODEL P137G, ST 20TFKN3 LA-K491P REV:2.0 (A01) and its quite a challenge. It powers on with the battery disconnected, lasts on for about 15 secs, and then shuts off. It does the same with battery only (no adapter). With battery and adapter it sometimes starts after hitting the button several times. It displays nothing in every case. Since only the Boardview is available, I guided myself with schematics similar to this laptop (I'll add them down).Some measurements:
1- After receiving power SIO_SLP_S0# goes high and never changes.

The issue with this video card is the HDMI port. Specifically on pin 19 (Diode checks on all other pins are normal). When i do a diode check on it from the pin on the board itself, I have nothing. There is also no short on the pin. Resistance reads about 200k. Normally on any HDMI pin 19 I would expect some voltage drop anywhere from .5v to 1.2v but here, I have nothing. The card is operational and can be used via the displayPort ports, but not through the HDMI. Attached you will find the pdf schematics for the card on page 22. I have verified that all of the resistors on this line before the...07-25-2024, 09:49 AM

Hello all,
As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere... -
I’m looking for some advice troubleshooting an old Chiefmax 650w power supply in a PC, if it’s advisable to dig into it.
Worst case I can replace the PSU, I’m just interested in learning the troubleshooting process. However, it’s out of my area of expertise and I could use some direction.
During PC operation I heard a loud pop noise, like a cap gun and the tower lost power.
Initially there is no power output 3.3v, 5v, or 12v when jumping the power on pin to ground. Also, no fan power.
Opening the PSU the only things visible initially...
