Re: Bush LCD37TV016HD
yes get you now,does the blue/brown wire have to be plugged in to the pcb ? just use a paper clip to cross wire across plug ok.Comment

'IF' i dont get any reading doing this what will this confirm ?Comment

Re: Bush LCD37TV016HD
I have to go now - it will confirm that
1 the switch doesnt work or
2 the wiring at the switch is defective or
3 the wiring at the kettle connector is defective ( You have said that from the kettle
plug to the mains plug is ok)
OR your meter has an intermittant fault - are the leads on it sound?Please upload pictures using attachment function when ask for help on the repair

Re: Bush LCD37TV016HD
Don't plug the connector with the blue/brown leads on it to the PSU board, as you need to get access to the pins on the connector.
Putting your meter probes on the 2 pins on this connector should give a reading of almost zero Ohms when the rocker switch is in 1 position, and open circuit when the rocker switch is in the other position.
If you cannot find something to short out the pins on the mains plug, you could also try putting one probe on the Live pin of the mains plug, and the other probe on one of the pins on the connector that goes to the PSU. One of the pins (probably the one connected to the brown lead) should show zero Ohms when the rocker switch is in the ON position.
Then put one probe on the Neutral pin on the mains plug and the other on one of the pins on the connector that goes to the PSU board. Again, one of the pins (probably the one connected to the blue lead) should show zero Ohms.
It would be a little easier if you could show a picture of the actual path of the mains wiring inside the set from the kettle socket to the PSU board. The photos you posted earlier just showed pictures of the PCB's with the mains wiring underneath.________________________________________________

Re: Bush LCD37TV016HD
Pictures are getting better - can you show the other side of the switch in the last pic.
Is the rocker switch and the kettle socket together in the same unit?Please upload pictures using attachment function when ask for help on the repair

Re: Bush LCD37TV016HD
Ok - Think I have got it now
In the picture it looks like you can get to metal connectors at the base of each wire by pulling back the shrink a little.
Working only on the switch - no kettle lead and not plugged into the board. Meter on ohms can you get at the metal under 1 and 2 on the pic test with switch one way then the other. This should bottom out if the neg side of the switch is working.
EDIT should perhaps have said put one probe from the meter on 1 and the other on 2Attached FilesLast edited by selldoor; 03-15-2013, 06:29 AM.Please upload pictures using attachment function when ask for help on the repair

Re: Bush LCD37TV016HD
Ok,if the switch is in the on position it is fluctuating between 0.12 0.14 when it is off nothing.Comment

Re: Bush LCD37TV016HD
This really doesnt seem to be making much sense. It is almost the same test as in 106/107
Put the switch in what you believe is the ON position and do the ohms test from the
neg pin in the kettle socket to the first the blue position marked 1 then the blue position marked 2
I am still wndering about your meter Hold the probes together (in one hand cross them and hold between thumb and forefinger)) and it should go almost to 0.00 then gently tug the probes and see if it goes to 1 on the left side or OL or whatever it shows when
the probes are apart.Please upload pictures using attachment function when ask for help on the repair

Hi,
Trying to fix a bush TV. The Tcon is integrated onto the main board by the looks of it but before I buy a replacement does this look like a screen fault? The lines at the bottom are concerning me. I have check for shorts on the caps etc and can't see anything obvious. Nothing is overly hot and I've tried heating different boards and pressing down on the flex but no change in picture.
Any advice welcome. Thanks in advance.... -
Hello everyone. 😀
As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.
Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
There are no devices that have exploded or otherwise show signs... -
I have been having a fun time at work with two pieces of equipment that had shorted components or shorted component cables to machine frame
I would check what my multi meter was telling me about how many ohms I getting with the multi meter was telling versus the ESR was telling me about weather or not it really was a short to machine ground or not
One note at first we thought that it might be a bad I/O card or a malfunction PLC including me as well but I thought I would try and see if removing the I/O cables would make a difference or not and this time it did make a difference... -
Hi, I was recently given a Bush Smart TV by a friend and the main board seems to be hanging on by a thread.
Before we get to that, my first obstacle was figuring out the model number since the back sticker has gone for a walk. Upon taking off the back case, I noticed the following Vestel parts, 17MB95m mainboard, 17IPS71 (what I'd assume is power supply) and a VES420UNVL-3D-S02 display panel. After doing some research I think the TV I have is a Bush ELED42240FHDCNTD3D, based on the matching image here (https://www.manualslib.com/manual/11...td3d.html#manu... -
Hello,
I have a strange fault with a Lenovo ThinkPad E14 G2 (Board No. NM-D011 Rev. 1.0).
The first Problem, which I fixed already, was a dead TPS65944AD (USB Type-C) controller. After I fixed this fault, all functions working fine and the notebook run very well with the charger and battery.
On the next day, I tied to start the notebook with the battery, but nothing happened. I started with the charger and on windows, I saw, that the battery was empty. And this was nearly impossible, because the battery was charged. I disconnected the battery and found out, that the board...
