Try this:
Access menu service by press on your command, with your TV OFF:

INFO + MENU + MUTE + POWER ON

Then you should get access to Service Menu.

The last item says: RESET

This will do a reset to the TV.

Make no harm.

WARNING: If when on service menu you feel tempted to "screw" on anything FIRST take note on ALL you change! You can compromise the TV ...

SOURCE: Samsung LN-R408D - No Picture

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.

just spoke to Samsung support and it turns out that the freeview tuner had froze and needed resetting. To do this put TV on standby and then push in series these buttons on the remote: 'info, menu, mute, power' the TV will then turn itself on and display a menu. Press the 'down arrow' untill you've highlighted option 12 - 'reset' and then press the 'right arrow' to enter the option. TV will turn off and when you turn back on it will start in 'plug & play' mode as if new. Set the time and country options and then it will perform a complete scan. I've just retuned mine and all back to normal. Hoorah!!!! :-)

My samsung smart tv hdmi ports do not work anymore


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Sony kdl-46xbr8, reset all settings, software update, nothing helped, all hdmi ports doing the same, the GUI does not have this issue so I know it's not the LCD screen, it happens only on hdmi


I had this happen and know what you are talking about. The tech guy talked me over the phone on how to fix it. He said the problem was a hang up issue, like the hdmi ports actually hang up the line like a phone call. He had me turn off the auto detect settings that talk to the other components and share info with each other. Then he had me reset the TV. It was a while ago so I may have reset the TV first then turned off the auto detect settings. Play around with it and I bet you will get it figured out.

INPUTS NOT WORKING


If the HDMI inputs are not working, contact Samsung for the country you are residing. They can talk you through a factory reset, this will reset all the main baords and setting which may fix the issue.

HDMI inputs stopped working


I had the same problem with the HDMI connected to my HD cable box DVR. We called the cable company and he changed the box and the problem remained. He said there was something wrong with my TV.  The component (5-wire) jacks on input 5 work fine.  A few months later i got the 'green tint" problem and the tech came out to replace the whole optical box.  I asked about the HDMI problem and he said that the Sony protocol for HDMI is the problem. It will "talk" to some hardware and not others. He has not found a fix, except to use the other A/V inputs and abandon the HDMI (#7) input.
