Philips 47PFL4606 Powers on, works normal then powers off after a minute

[simwalsh]

Hi,
I am new to this forum and have searched for some answers with problems similar to mine.
Philips TV powers on as normal for about a minute or less then click and no power at all not even standby light. If i disconnect from mains and reconnect it will power on again but for a shorter time. Once i leave it disconnected from main for a longer time it will power on for a longer period the next time.

It sounds like a power supply issue?

I have the board out and want to run some tests. Not sure what i should be doing but i put a 1k resistor across SB and +5v...

Greetings and Salutations,

I have gotten an A1989 Macbook board number 820-00850-A which has two missing rails -> PP3V3_S5 and PP1V8_S5.
PBUS is at 12.6V every other voltage made by the PMIC is just fine.

Resistance to ground -> PP3V3_S5 ~ 220Ω
Resistance to ground -> PP1V8_S5 ~ 220Ω

PP1V8_S5 and PP3V3_S5 are not shorted together.

Voltages up to PP2V5_NAND_SSD0 seem to be fine.

Can anyone confirm if these resistances are normal for this board?
What could be causing this issue?
Is there a way to...

The device is quite old, M/V MBX-199 M820/M830
1P-0087J02-8011, the video chip flew (artifacts - no picture), removed the old one and installed a new one, but before installing the new one, the area under the video chip sank slightly and Pyataks were found, under a microscope, the contacts were not involved, it was decided to install. Now after switching on there is no initialization, all voltages are normal,
I couldn't find a diagram, maybe someone will have one. The MBX-199 motherboard was also installed on these models, but I couldn't find the schematics for these either PCG-2E1M...

Hello!

I have a TV that I can't get any further with.
It is a Samsung UE 55HU8590 with one connect box.
When I turn on the TV without the one connect box, the animation on the TV tells me to connect the ocb.
As soon as I connect it, the TV restarts (panel goes dark) and the TV tries to start continuously (relay on the SMPS clicks about every 3 seconds).
Since the TV works without ocb, I assume that it can't be the PSU?!
I have measured all contacts of the one connect cable against GND on the ocb board and there is no short circuit anywhere.
Is there...

[Sraros]

Hello,
I picked this PSU 17PW15-8 from a friend's TV with a burnt fuse, after some days of rain and lightning strikes. The TV was on standby when it happened.
With new fuses it burns them as well. I checked bridge rectifier, all the TO220 components, diodes and basic caps, replaced IC806 SMPS, and FETS driving the big transformer. I also isolated the secondary circuit by cutting the rails of the FETs to the primary coils. I don't know even know if that makes sense, but I did in hopes to isolate the problem.
Any ideas what to look for?...

Hello fellow Badcappers,
I have a problem with stubborn Surface Pro 7. I narowed it down to disappearing SLP_S4# (gone after around 200 ms).

Everything else works as it should (the whole power on sequence succesfully finishes, all the voltages are present) until this signal goes missing - with it missing the AND gate causes ALL_SYS_PWRGD to go back low and this makes VCCIN drop to 0 V as well. Interestingly the SLP_S4_DRV# signal from SAM is still present for a second, even after SLP_S4 is no longer there. I wonder what could either cause PCH to stop sending the signal or what...

Hello, I'm tinkering with this amplifier. The 'Current Drive' light doesn't come on, and the relay doesn't power on either.

I've identified a possible issue—I think—where Pins 3, 6, 12, 13, 15, and 16 have a positive voltage of 22V. However, Pin 18 shows 0 voltage, and Pin 17 registers -1V.

I'm considering replacing the SVI 3205 IC, but it costs 50 pounds. Therefore, I want to make sure it's actually dead before purchasing a replacement.

Any suggestions would be greatly appreciated.

I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
Since then, This AC/DC adaptor have been out of order.
But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
And Is there any possibility that it will suddenly explode as well as to be out...

I have a HP Probook 640 G4 laptop which does not detect the DC charger and therefore will not charge the battery. I checked the dc adapter on another working probook 640 and it functions adequately.
I checked the voltages coming in on the motherboard connector from the DC adapter to the bad unit and measured one voltage to be 19vdc and the other the center pin to be about 0.8vdc. I tested the battery and it was found to be OK.
I am not sure what the center pin voltage should be. I suspect the problem to be a component on the dc input line on the motherboard but I do not have any schematics...

hi everyone,

i've got this ancient board here, repairing it as an exercise really. it seems to be brain dead.

upon triggering start via SMC_ONOFF the fan starts to spin, USB powers up, CPU gets hot but there is no further activity.
nothing on the video output, no USB activity (using pendrive with an LED).

I've read the bios, it looked ok, valid checksums, model/.mb match etc.
I cleared VSS and wrote the bios back. NO change.

any suggestion as to what might be the cause of this?...

Dear friends from Badcaps
I have been searching for a long time to repair sucessfully a battery charger taking in 230V AC and outputting normally 14V DC. Its power mosfet has been shorted ( Infineon 06N80C3), probably because the bulk storage rectifier capacitor had swollen and had no capacitance anymore and a very high resistance.. The mosfet short has naturaly blown its 0.15 ohms resistor then its driver, the UC3845 IC which was shorted between pins 5 (ground) and 7 (vcc) plus 8 (Vref). Another small resistor surrounding was also dead. So, I have replaced the bulk storage capacitor, the...

[SzymonB]

Hello, I am asking for help. After connecting the power supply, the TV will first blink once and then after a few seconds it will blink 4 times. All voltages on the motherboard are OK, but when there is a cyclical one blink the voltages 3.3V, 0.9V, 1.5V, 12V on the L80 coil also reset. So this x1 blink is like Reset_SYS and then it's x4 blink. Where to look for the problem? There is no Service Manual, I rule out the problem of bios on IC401 because I have already done it. I found descriptions of SOS on the Internet and 4 x blink is Power SOS P Board Help. Regards

I have been asked to check out a faulty Bose Wave system belonging to a relative. The faulty unit produces loud intermittent pops and crackles. Sometimes there is speaker audio output (FM/AM, CD etc.), most of the time there isn't. This behaviour degraded over time fairly quickly, to the current situation where no sound is put out at all. Gently messing and wiggling wires, connectors or heatsink has no effect in force-replicating the problem. I have little experience in audio repair when it comes to (main)board electronic component faults. Bose repair WAS about 140$ (most...
