by stingerWhen I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem?04-17-2024, 03:06 PM

Hi.
My Hp G6 laptop died while using it.
I opened it up and used a thermal camera on it to see if anything was getting hot. The RT9513 chip (EQ ED B1Y) which is supposedly a battery charger ic was getting hot. I ordered a new one and replaced it but its still red hot. Where should I look next?Today, 10:02 AM -

by madjid911hello I have an acer nitro 5 model N20C2 (motherboard FH51M LA-J871P rev 1B) which does not charge, it turns on perfectly but when I plug in the battery, we see the charging indicator and the charged battery logo but it turns off a few seconds later, and there is no way to turn it back on, you must then disconnect the battery and the charger. If I turn it on without the battery it works fine.
I changed BQ24781 but the result is the same, I put after BQ24800 the same, I then checked all the resistors and mosfets, everything is ok, I bought a new new battery but the result is the same...Today, 07:58 AM -

by aaronkatriniHi all,
Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.
Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...04-18-2024, 03:15 PM -
by edugimenoHi everyone!
I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
I respected the polarity, positive to cathode of protecting diode
So provided all...04-18-2024, 01:15 PM -

by mikkele86Hello.
got this Luxman R-5045 vintage amplifier which need a good repair and service.
finally got i started up and started to check voltages.
My issues is that the voltage measured is 3,5v to 4v higher than whats stated in the schematic.
Meaning voltages like +9v is like +13v
and +31v is measured to 34.6v which is really close to the capacitors rating +35v
I measured the voltage before the rectifier and im measuring 27v
did a online calculator and it showed i should actually get +36v after the recifier :/
So my question...Today, 07:18 AM -

I came across this thing and im not sure what it is exactly, I have never seen such thing before.
I know it gotta be some kind of diode with Drain, Source and Gate1 and gate2
It resides in AM/FM module and im measuring 200ohm across D and S.
