Don't have any laying around.

Question: when i do get the resistor do i solder it to those pins or just put it with where the wiring goes?Comment

Re: Polaroid FLM-3234B - nothing comes on. Standby Power is Present.
Just try and squeeze it in where the wires are, otherwise you'll be soldering and resoldering it several times which can be a pain.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

So, adding that resistor does nothing.Comment

Got around to looking at the power supply again and i found this and i can't find a schematic of the Board.

Oh dear. Yes, that component looks like it has had a bad day. Z6 would suggest a zener diode. Approximately where is the component on the board?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

What resistance do the resistors 102 measure? They may be bad too. I think they should measure 1000 ohms.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

0.98 on 102 and 9.99 on 103Comment

Re: Polaroid FLM-3234B - nothing comes on. Standby Power is Present.
Okay, those look fine. Close enough for 5%.
That big thick trace coming from the zener area looks like the ground for the primary side.
This zener may only be the start. Something else could have been damaged. Was the TV killed by a surge, lightning, etc?
If I were to guess, it looks like it is part of a MOSFET gate circuit, so maybe 12 - 18V... but I wouldn't be certain. That is the problem without a schematic to go by.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

looks like when it burnt out one side of the green layer came up. so the board is more less screwed id imagine.Comment

Re: Polaroid FLM-3234B - nothing comes on. Standby Power is Present.
i just have a question about the same power supply being discussed on this thread.
i have a polaroid TC18607A power supply from polaroid TV FLM-3232. it started having the video come in and out. then no more video. i suspected the power supply so i started removing loads. i removed the 2 tuner boards and leaving just the main board powered by the power supply since i don't use the tuner coz i use directv box on the hdmi input.
it worked for hours until i turned it off for the night. morning comes and i was excited to see the TV working again but to my disappointment, it turns the back-light ON and no more video even the POLAROID logo. it has audio but no more video.
i opened it again and checked the power supply voltages. my readings:...the 5V gives 4.6v - the 12v gives 11.3v -the 24v gives 23.6v. this is with and without anything plugged onto the connectors CON5 and CON4.
i dont see any bulging caps and everything looks normal except for my voltage readings. i used a 2nd meter and it always was giving less than the voltage it supposed to give on the pins.
any inputs i appreciate. thank you.Comment

Hey All,
I have a Sony 65x900f that I purchased cheap because of a no-power issue.
I assumed that because there is no standby light visible, it would be an easy fix - however upon opening up of the unit I can confirm that the 3v3 standby voltage is making it's way from the power supply to the main board. I'm a little confused as to why there is no standby light.
I am firstly wondering if anyone has this model of TV, or has worked on one and can give me some insight. I have tried to find a service manual for this model, to no avail - and would really appreciate... -
This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.
Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today.... -
Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated. -
Hi all.
I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.
Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.

Hello forum. I've recently been given a Yamaha TSX 120 DAB radio and ipod dock. Its working well however when put on standby its using 6.3 watts. The manual states less than 1 watt on standby. I measured this with a plug in monitor which seems accurate with other items. In use it uses around 7.5 watts. Firstly has anyone who owns a similar radio also got a plug in monitor to check if this is normal with this unit? In the first half a second the monitor shows 0.3 watts which I suspect is what it should use but something is switching it to be almost fully powered. I've searched the manual for eco...03-01-2024, 07:25 AM
