does anyone have a service manual for this guy? 32MF231D/37 found a parts list from elektrotanya but need to see the schematic for the power supply. no load its fine right at 24V. under load of the inverters its pulsing all over and flashing the screen then shuts off. can hear a buzzing from the transformer on the power supply. replaced the power supply already but it was an ebay item. doing the same thing

Re: 32MF231D/37 pulsing 24V under load, backlight flashing
There are four SMD MOSFETs (8-pin) on each inverter board. Can you read the P/N to get the pinout to check the Source and Drain pins for shorts?Never stop learning

Re: 32MF231D/37 pulsing 24V under load, backlight flashing
i repaired my own tv...(a magnavox).. that had that buzzing sound. i thought it was the transformer for the longest time till i tried a can of air. turn it upside down and spray the part you think it is. i found out it was a zener diode that was the problem. replaced it and the tv turned right on and worked. it was right under my transformerComment

450V capacitor can go bad causing this issue, if all else tests good.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search.Comment

by stav242I was asked to look at a Sony KD-55X8509C as it was not powering on, no lights.
On inspection, there was no physical issues.
I seated all cables and repowered the TV, then the LED light flashed Green / Amber.
- this seems to indicate repairing required, done by Firmware update.
so downloaded the latest Firmware from Sony website and wrote to 4Gb USB drive.
Inserted the drive and repowered the TV.
LED changed to white flashing/pulsing ... and it sat there for over an hour.
i was unsure what was happening so repowered the TV and now it just... -
by speggio91Hello everyone!
I have this board that got slightly water damanged and it is stuck at S5 state. It pulses once every 5 seconds.
When connected the magsafe 2 to the bench psu, the current goes from 0.02A to 0.10A when is pulsing.
When using the genuine magsafe 2 charger, the light turn on and it became green and then amber. The fan is not spinning.
When I tried the SMC bypass mode, the fan spins a quarter every 5 seconds and the pulsing is still present every time the fan spin.
The pulses are present in the CPU Vcore rails on L7320 and L7310.... -
by STKR123As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -
by AJ847.63eHi Folks,
Just wanted to clear up a misunderstanding of mine (or what I expect is one). Isn't the 12V rail from the 24 pin, EPS and PCIE separated? IE if I put a power resistor on the ATX 12V pin that is not going to load, thus tell me if the EPS or PCIE rails are fine?
I was recently watching ArIs from Hardware Busters video on how to properly test ATX PSUs without using 5 figure Croma substations.
The PCB adapter he used breaks out the 12, 5 and 3.3V pins from the 24 pin and gives you banana plugs to connect to. That is a bit useless is it not? Aren't... -
