Hello.
I received a bios locked 7410 with 25Q256JVEQ ,i dump the bios, unlocked it and flash it back, since then the laptop has no life signs at all except amber led on for as long the power button is pressed, nothing else.
Fact #1 i was unaware that 25Q256JVEQ is 3.3v and i used a 5v CH341A to program it, not sure if the chip got damaged but since then i can read it and write it normally, doesn't seem dead.
Fact #2 i modded the CH341A to 3.3v, same results with programming though, nothing changed.
Fact #3 i tried hard reset with cmos/main battery disconnected and power... -
I have a XR-77A80K here. When plug in & press power, white lindicator light flashes on & off. about 30 seconds later, indicator light flashes 8x red. Checked Sony, Power reset = unplug & plug in. Factory reset involves turning it on, then pressing remote buttons when a picture shows. Well, neither of these "resets" are for a dead set like this. Anyone know what 8 blinks indicates, from the schematic? Thanks! -
Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.
Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner... -
Hello, got a nice 70'' Samsung here that has this symptom, it's (it was) dead with flashing red light, backlight going on and off, looping trying to start up.
So i digged here and youtube, and found the tape method. Got the tv to fire up, however i'm trying to understand what's wrong with it.
At the bottom of the tv, on the panel's PCB there are 3 sections, each of them has 4 connecting tabs to the panel.
So with convering a few pins the tv works, and i messed the flex cable doing so, waiting for a new one to come in to continue troubleshooting. ... -
Hello,
I got this TV (Westinghouse DWM40F1G1) that did not came on one day, blinked for a split second and turned off. I looked at it closer with flashlight and figured that the TV actually works, its just the backlight that does not.
There is one PCB board - all of the components are on it: TP.MS3393.P85
I took my oscilloscope and looked what is coming to the MOSFET that is switching current to LEDs - I could see that the PWM signal comes in but it cuts off almost instantly. I thought its the driver chip OB3350CP and so I replaced it.
After that the...
