Hi, I tried to connect my laptop (xp) with my Samsung UE32F5000AKXXU via s-video scart cable and when I shared the screen my tv went dark purple. Since than I can hear only sound but no picture. My remote is working but I can't see what I am doing. Can I reset it somehow? Is that will help? I tried to turn it back with the pc but it doesn't work.

SOURCE: samsung tv turning off by itself

I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.

SOURCE: Stopped receiving sky on second tv - does my samsung need a reset

I install a lot of magic eyes etc.

You have checked that the magic eye lights up when it is connected directly into the sky box. So your eye is working correctly.

the next step I would take is with your sky remote in your main room. press SERVICES, 4, 0,1, SELECT go to RF settings and check the rf channel and make sure the power is on. Take a mental note of the channel number.

Now go into the room where the link is feeding. Turn on the TV and go to channel number 6 press your MENU button and then go down to setup. go across to manual install and then down to the channel number type in what you retrieved from you box ie rf channel and then type it in and STORE.

If you go into your main room and just put the normal tv guide on ie blue screen. then check that your getting the sky into the other room. IF you are then great it just needed tuning in. IF not I would remake the coax connectors. as there may be a bit of copper braid touching the centre core. once this is done your sky should be on all you need to do now is put the eye back on. Once you have done this the red light should appear on your magic eye. if not go to your main box and follow the first instructions I gave you and turn the power off on the RF and then save and then go back in and turn it back on and save.

Hope this sorts out your problem

My Mom's LNR408D also had sound but no picture. I was able to fix it by soldering in a jumper wire across a blown (1.5A ???) SMD picofuse on the "T-Con" board.
Consider attempting this ONLY if you: 0) Know enough to avoid the potentially fatal High Voltage parts of the power supply board!!!
1) Are a fearless hackazoid 2) know what you're doing with a soldering iron and teensie SMD parts 3) are gonna throw the busted thing out anyway so you have nothing to lose and won't be sad if you screw something up.
4) Know enough to avoid the potentially FATAL High Voltage parts of the power supply board!!!!!


This board is at the top center under a close fitting RF shield. The suspect part was labeled "CP" on the board and marked with "P" on the part. It is visible above the right-center of the connector from the main board. An ohmmeter showed it as open, so I bypassed it with a jumper wire from connector VIN to the hot side of C13. One image shows the suspect part and the jumper in place.


The other shows the TCON board placement top-center (under its RF shield). With care, it seems possible to test the fuse and put the jumper in place without removing the shield. (Obviously don't touch anything else with the VOM leads!)

Thanks to ZORBUS and Steve's TV and Electronics for the idea.
