Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
Thanks I will try this and come back when i get the result. I sent away for uy connectors too. I used ethernet because i could send the power and video down the same line. The price of sat cable with power was quite dear and i already had cat5 here hence why i decided on that. I mean it does my job. Eventually I will be upgrading to ip cameras and an nvr but will try to get the interference stopped in the meantime.
Cheers again for the help

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
Hi thanks for the reply. Yes i must say there is certainly crosstalk between the different display images when viewing. At the minute i am uaing baluns at the cameras the cables run into the loft into a 4 ch balun. The only reason i did this was to send all 4 channels down the one ethernet cable. I have no baluns at the dvr but did try them to no avail. I also tried the ground loop blocker but nothing works.
You may be onto something with the cheap 4 ch balun. It was an ebay special (lol). I might do...Last edited by mrdiy88; 11-10-2018, 11:38 AM.Leave a comment:

Re: UE55D8000 Power Cycling On Off Issue
It was the leds. I sent them over to Mike but never heard back again so ended up selling the parts and dumping the tv at the recycling center.Leave a comment:

CCTV Vertical Coloured Lines Rolling Across Screen Interference
Hi guys. I have installed an AHD CCTV system (Hikvision) at my house. I have used solid copper cat5e cable coming from the 4 cameras into a 4 channel balun in the roofspace. Then I have ran a length of cat 5e cable from that down to the DVR. The DVR is connected to the TV via HDMI. The cameras transmit using TVI.
The cams are powered using a single 12v 5a psu and 4 way splitter in the loft.
When I have only one camera connected to the power supply the picture is perfect and very impressive. This is the same for each camera if only one is powered at any one time.... -

Re: UE55D8000 Power Cycling On Off Issue
Should I disregard other advice to bypass these? I was told this by the local repair guy but I know it probably not the correct thing to do. I noticed when I tested the points using a resister the lights start to light as expected when ac is applied.Leave a comment:

Re: UE55D8000 Power Cycling On Off Issue
Update, I have looked at the led strips and when the cable is removed from power supply to main board there is indeed voltage present at the led strips. Could it be that the 2 broken off leds are causing a break in the loop?Leave a comment:

Re: Starter Capacitor Kits in the UK
That's a great idea Vince, I think I will do the same, good way to do it. I agree too a chart would be brill. I have filled my cart on a few occasions now but wasn't 100% sure. But time is a good teacherLeave a comment:

Re: UE55D8000 Power Cycling On Off Issue
I have tested the power supply and it tests good so I am now looking for the LED strips for the set if I can get them. I have literally looked everywhere. If any of you can find these please let me know.
TV Model: Samsung UE55D8000YUXXU
Prod Code: LTJ550HQ04-J BL-UE55D8000YUXXU
I was able to hit up a search for the exact ones I needed here but they are out of stock. Whats a man to do? [url]https://www.tvparts.co.uk/ltj550hq04-j-bl-led-backlights-for-samsung-ue55d8000yuxxu[/url]

Re: UE55D8000 Power Cycling On Off Issue
These look the same but i would prefer the whole bar. I have attempted to solder on the broken one but it was total pain. If I find the edge lit led strips ill jump at them (at the right price ofcourse). There were no model numbers on the strips just a sticker as in the image...Leave a comment:

Re: UE55D8000 Power Cycling On Off Issue
Sounds good to me. Budm is working on some testing I believe but I know he is busy at the minute. If you guys see suitable led strips in the UK please let me know. I'd be eager to get a set.Leave a comment:

Re: UE55D8000 Power Cycling On Off Issue
Yes still the same. With mainboard disconnected the power supply is on but not even a flash from the leds. I can see votages at the top half of the supply so shes definately on. I always thought the leds were supposed to light.Leave a comment:
