someone in the thread mentioned disconnecting the dvd drive did you try this?

Re: Magnavox 32MF369B/F7 volume stuck
No. Private is private - only you can view, no matter who has the link.
If you want it publicly viewable but not searchable, you want to set it as "Unlisted".
I have seen those tactile buttons go shorted and other wacky things, and they don't show as shorted consistently when tested with a meter.
I would certainly try the set with the buttons disconnected. Just desolder the cable.Last edited by Agent24; 01-08-2017, 05:46 PM."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Magnavox 32MF369B/F7 volume stuck
thanks. only thing im worried about is when i disconnect it i won't be able to put it back for whatever reasonComment

Re: Magnavox 32MF369B/F7 volume stuck
Do you know how to solder OK?
If not, you will have to learn anyway, if you need to replace any of the buttons, if they're bad."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Magnavox 32MF369B/F7 volume stuck
yes I can solder. I am referring to the solder strands a new part comes with that you snip off once it's solderedComment

Re: Magnavox 32MF369B/F7 volume stuck
OK, but I'm not sure I understand what that has to do with desoldering the wire?"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Magnavox 32MF369B/F7 volume stuck
what I mean is if i desolder the button board at the plug connection, and that just so happens to not be the culprit, I would have to somehow solder it back and that's my worry; the plug being able to be reinserted through the board.Comment

Re: Magnavox 32MF369B/F7 volume stuck
Oh, well there should be no big problem there, if you desolder it cleanly.
Do you have desolder braid or a desolder pump at least? That will allow you to remove it with clean pads and no solder blocking the holes. Also the wires will be free of too much solder and easily re-insertable through the holes afterwards.
It won't matter that the wires\leads are not very long, they don't need to be, they only need to be long enough to go through the holes and solder onto on the other side."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Magnavox 32MF369B/F7 volume stuck
oh, no I do not. looks like i need to invest in one of those. which one would you recommend for meComment

Re: Magnavox 32MF369B/F7 volume stuck
If you're just doing the occasional repair etc then a cheap one like this would do:
https://www.amazon.com/RadioShack-4-.../dp/B00ZXADYLO
(I have one much the same, I like the all-metal construction. I have heard of the cheap plastic ones breaking easily)
There's also http://www.edsyn.com/product/DS017.html which is very popular.
Solder braid is also handy. It's good for cleaning up the pads afterwards in case any solder was left.
https://www.amazon.com/Aven-17542-De.../dp/B017ODKIPC should work well.
2-3mm width is good for most uses. If you get a different one, make sure it has flux in it, otherwise you'd need to buy a flux pen too.Last edited by Agent24; 01-11-2017, 07:46 PM."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Magnavox 32MF369B/F7 volume stuck
ok I'll get one of these soon. you think I need both?Comment

Re: Magnavox 32MF369B/F7 volume stuck
For this particular scenario, you could desolder those wires with either tool.
Just make sure you reflow the joints to be desoldered with fresh solder before you start, it will make the job so much easier.
The desolder pump is great for removing the bulk of the solder and getting the leads\wires free. The braid is great for cleaning up any excess solder afterwards.
In general, I would recommend someone working on electronics to have both, as they complement each other.
For example, if you have to replace surface-mount components, you NEED braid to clean up the pads and make sure they are flat, before soldering in the new component."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Magnavox 32MF369B/F7 volume stuck
sorry for the late replies on this, but i just got my tools in and I've been focusing elsewhere. I'm ready to hit this again. I was just thinking and looking at the button board, if I desolder this board, how am I going to turn it on? 6 buttons on the board, I think 1 is power as I don't see a power button anywhere else.Comment

Re: Magnavox 32MF369B/F7 volume stuck
i think the easiest thing for you to do is lift 1 leg of r114. you will have to confirm, but it looks like it feeds from the volume up button. this way you will only have to lift 1 pin and still have access to the power button.WHY CAN'T PHILIPS USE PHILLIPS HEAD SCREWS?Comment
-
Re: Magnavox 32MF369B/F7 volume stuck
ok now does it matter which leg of r114?
also you're saying the power comes in and goes through volume up, and then to power?
how do you propose I test this to confirmComment
-
Re: Magnavox 32MF369B/F7 volume stuck
upload a good clear pic of the left side of the board (i think. the area around the volume up button.) and we will confirm that it is the right resistor.WHY CAN'T PHILIPS USE PHILLIPS HEAD SCREWS?Comment

Received a faulty HP elitebook from my friend that does not boot up properly. The internal display is broken, so the only way to view the display output is via hdmi. However, when booted up the screen get stuck with 'Entering setup menu...' when esc is pressed upon booting. HP logo isn't displayed on bootup, only black screen, but an underscore cursor appear on top left corner of the screen. Has anyone any idea what could be the culprit here? I have flashed both the EC and BIOS flash but to no avail. The serial number is 5CG9377GCT, and below is the original flash content:

Hello all, I've been looking into this portable air conditioner's remote control and can't find what could be causing the problem - or possibly this remote is just terribly designed.
The remote only works at exactly 3V - if I drop it any lower, using my bench power supply, to say, 2.9V then the remote will not flash the display and turn off. I don't have any AAA batteries that are exactly 1.5V each so I'm not sure if this remote is designed this way - to only use the freshest possible batteries, or if there's a failed component in the mix.
I can't find any schematics... -
This is a 2012 LG TV so aware full functionality of the smart functions/apps will be limited however currently unable to get the LG Smart Store.
Youtube, Netflix and LG Smart store icons briefly appear in the apps list but then automatically disappear after doing 'Initialisation of Premium' via the standard menu, I'm guessing this is due to the Country/Area group its set to is wrong for the UK.
Unable to change the country group, Area option can be changed which alters the country group but none make any difference. So believe its the country group that needs changing.... -
Hello esteem members,
I have a JVC Television that fails to turn ON sometimes. The stand-by red light is always on. When the TV turns on the the JVC logo displays then the TV attempts to scan for local channels...it then freezes. If I unplug it, then it refuses to turn on - stand by light on. The power supply input voltages are present - 12V, with the backlight 0.32V when the TV refuses to turn on. Backlight voltage is 2.98V when TV does turns ON. All regulator chip has 3.3V on pin 8. Processor voltage - 1.02V, Ram - 1.5V. I am thinking about reflowing the on-board RAM. When the TV was...
