Hi I have a samsung 26" LE26R87BD tv. I have been fault finding because it turns itself off and on after about 5 minutes of use. I have figured that it's a heat issue. I can place a fan behind with back off and it will stay on. Has anybody got any input on this model of tv.

Re: samsung LE26R87BD power cycling when hot.
Memory serves me right the small blue ceramic cap next to the PFC can cause all sorts of problems with this set. -

Infact scratch that it's the le26a model.
Think yours is a different PSB.

Hi all
There's two other threads about this monitor with seemingly the same problem. The problem was resolved in one case by replacing the entire PSU board and in the second one by replacing an unknown IC.

The first one has pictures of the pcbs and I noticed that there's one IC and assorted caps not populated on mine (but the PCB itself looks identical) so I thought that'd warrant a new thread.

Samsung UN55FH6030, perfect size for my office and does OTA well but isn't a smart TV. That's OK because I am a TV station engineer and only need it for OTA monitoring.
About a month ago it started power cycling itself once or twice a day and now it's nearly continuous once it's been on for a few minutes. Changing channels would really start it cycling and it would take several minutes to stabilize but now it's just doing it almost non-stop without changing channels.
Once I disconnected the antenna I found that I could change channels with no issues. My guess is... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi All,
First time posting here ... my name is Kevin but my friends call me Journey.
I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again.... -
Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.
