by TopcatI got paid to take this. It had the typical DPS STBY IC bad. Replace it and life was grand....or so I thought. I've never seen this one before; this TV will just magically turns itself on for no particular reason on earth. I did a hard reset on it (twice) clearing all data & settings out.....will still do this. Even removed the batteries from the remote....in the unlikely even there was a stuck key... Still doing it. I did not set up any of the 'smart' functions, I just fed it a source from a HTPC. It doesn't matter what input is selected.....still does it. No rhyme or reason as to frequency....Today, 05:00 PM

by BholuToday I got a 65" TV from Hass company. It was not showing any picture. I taped the 6 lines of the Tcon FFC cable on the faulty side of the shade and the picture came but the display on the side where I blocked the pins was not showing properly. I checked the volts on the VGH point and -3.5 volts was abnormal, there should be about 28 to 30 volts on this point! There were +30 volts on the VGH point on the Tcon. I put a jumper on the source PCB from the Tcon side and saw, the raster started appearing on the display. I also tried soldering the 6 blocked pins but the picture did not come properly....Today, 04:54 PM

by BholuHello friends, I have MTC 58' TV which has stand by position. I thought the software was corrupt. I have downloaded the software from the internet but the data is not matching. The format window is opening from the TV software but none of the buttons on the remote or TV are working. Why? Can I edit this software with a hex editor? Is there any guide to edit this? Or does anyone have access to this software? Thank you very much for your help.

Hi, everyone. First post of an actual repair. I'm a technician but a complete newbie with laptops.
So I got this Dell Inspiron to play with.
No charger, so I connected to my bench PSU.
The laptop also didn't include: hard disk (I added one of my own for testing, see below) and wireless PCB (but I doubt this could have anything to do with this particular failure).
------What it did (and didn't do)------
1) I turned it on and it powered on. Powered down in 2 seconds by itself.
2) Removed RAM, changed slot. Same...04-04-2024, 12:39 PM -
by JupTecHallo zusammen! Das oben beschriebene TV-Gerät zeigt, wenn es eingeschaltet ist, für ein paar (5?) Sekunden am rechten Bildschirm-Rand nur die Zahlen 47, 48 und 49 untereinander. Die 48 in der Mitte ist etwas größer. Dann schaltet sich das Gerät in der nächsten Sekunde aus und wieder ein ... Dieser Kreislauf ist endlos. Mit der Fernbedienung kann nur ein/aus bedient werden! Sonst nichts. Wenn eingeschaltet, kann ich durch Löcher in der Panel-Rückwand sehen, dass der gesamte Bildschirm aktiv ist (zartes blau), aber kein Inhalt - nur die 3 vorhin beschriebenen Zahlen. Ich habe an der...Yesterday, 12:34 PM

by SatdudeHi, I have a Yamaha RX-497 receiver, and one day I came home to a burnt smell and the breaker was tripped. Upon opening the receiver, I saw extreme damage to the main power board. C254 was exploded, R261 was burnt, D255 was shorted, Q254 is open circuit, D261 (bridge rectifier) is also open, traces to IC252 (TC4013BP) are vaporized right off the board. Not sure about any other damage, I'll have to desolder the flip flop to test it. Also the transformer T251 is getting hot when plugged in. What could have caused such extreme damage just sitting plugged in? Only repair that was done in the past...4 Photos

by TheOtherGuySo I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...Today, 07:27 AM

by KibergeHI guys!
I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊
the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.
This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...Today, 11:28 AM -

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?04-20-2024, 10:02 AM -
