SOURCE: Samsung LCD Flat Screen TV LN-S2651D - Volume Problem

I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.

I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.

This tv has issues with 4 capacitors. These caps can be replaced for about $10. They are located at the top right corner of the power supply. They will read 10v,1000uF. I had the same problem, then I replaced them wit 16v,1000uF capacitors. And presto tv!

The main board may cause this problem. If it wass happened when you play DVD, so the main board needs replacing.

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.

Samsung LNT-4665F won't power up properly


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

NEED MANUAL FOR SAMSUNG MODEL LNT 1953H LCD 19''


..review of the product and related issues:

http://www.amazon.com/review/R2LL7LEO1ABLU8

Crutchfield's take on that model and it 'ease of use issues':

http://www.crutchfield.com/S-rsaLPNJLHDO/p_305LNT1953/Samsung-LN-T1953H.html

..more specifications from that site + related comments:

http://www.crutchfield.com/p_305LNT1953/Samsung-LN-T1953H.html?tp=161&tab=detailed_info

...manual download page for 19" LCD series:

http://www.samsung.com/us/support/detail/supportPrdDetail.do?menu=SP01&prd_mdl_name=LN19B360C5D

Rule of thumb is check a similar product in case you can't find exactly what you want. Discussions on those other sites indicate they only have "user guides" for the LNT 1953H LCD 19" ..and nothing in the way
of serious service manuals (i.e. for the consumer).

4665 samsung has sound but no picture


Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent.
