Hello to all. I have a problem with Andersson Tv. Inside it there are Vestel boards Vestel 17MB35-4 060109 and Vestel 17PW26-4 PSU. It turns off but again turns on. All caps looks ok.
Thanks in advance.
Thanks in advance.

Re: Andersson (Vestel) won't turn off
Unplug the button board and see if it still presents problems.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Andersson (Vestel) won't turn off
I unpluged touch button board, it wont power on. Status led goes off and then on. With all connected when I plug cable in power soccet, tv automaticaly powers on.Comment

Re: Andersson (Vestel) won't turn off
Ah. I forgot that Vestel TVs do that, which is annoying! Can you try plugging board in, turning TV on, turning off, then quickly unplugging it?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Andersson (Vestel) won't turn off
I tried that. It just turns on and it is like I pressed volume+. Just tried one thing. Warmed PSU with hairdrier at the area of big cap and small transformator. TV then goes off by itself.Comment

Re: Andersson (Vestel) won't turn off
I think it is more likely to be a main board or button stuck (touch panel) issue myself. One thing you can check is the STBY pin on the PSU. It should be high (>=2V) in standby, low (~0V) when running. If it's going high when it should be off, it could be a PSU issue. Is it marked on your PSU?Please do not PM me with questions!

Re: Andersson (Vestel) won't turn off
It is like this.... Sometimes I get 0V when off, then it stays off. Then it powers up. Strange!!! Can it be tny266??? Cause I warmed that area and tv turns itself off...Comment

Re: Andersson (Vestel) won't turn off
Hmm, I suspect you may have a cold solder joint. The TNY266 is the standby power supply. If that fails TV will switch off. But it could be failing due to cold solder, which means other parts could have cold solder too. I would suggest you try resoldering anything that looks suspect.Please do not PM me with questions!

Re: Andersson (Vestel) won't turn off
Can you tell me from where does it gets standby voltage on pin??? I resoldered touch panel and didn't removed flux, so it powers on and off, and it holds volume-. Cleaned everything with alcohol and it is working normaly. But when it is in its place powers on and off... I suspect it has gremlins.

Re: Andersson (Vestel) won't turn off
Main board generates the signal when it receives a signal from remote control or touch panel.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited... -
Hello,
I need advice in troubleshooting Telefunken TV (it is actually Vestel). There is red Standby light but TV cannot be turned on either by remote control (which is good and tested on another TV) or by actual on/off switch at the back of the TV.
Power board is Vestel 17IPS71 and I'm not sure about the mainboard, it seems like 17MB82S
Both boards are shown in the attached photos.
What is normally first that is checked in this case. I have removed power board, make sure it has no dangerous voltage on the big caps and check many components (transistors and diodes)... -
To all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But... -

Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the...
