Open Question

HDMI jack is loose/wobbly

I have a 3 1/2 year old 40" Samsung LCD w/ only 1 HDMI jack. It is now wobbly and partially seperated from the circuit board. How difficult is this to fix? And does it need professional attention or can I do it?

SOURCE: Loose HDMI Connection

Dont use the HDMI connection OR replace the main board. Its directly soldered to the main board. The back should come off IF you have removed ALL the screws and the little screws things that hold on the VGA connections etc. There are also some obscure screws holdin the back on.

SOURCE: My samsung tv turns on and off repeatedly at

Mine was doing that then it quit even turning on so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.

SOURCE: no picture on Samsung LCD 40" TV

Nobody could guess that! it depends on where you are in the world. For Instance I am in australia network.
Call outs generally run to $AUD90 and $90 and hour Min 1 hour.
You do not say whethyer the power light lights up so its again guesswork.
If the power light IS lit then there is power from the wall to the primary coil of the power transformer. I would then suspect either the secondary transformer has failed, or that a fuse after the secondary and pre picture/sound module has blown. The power supply ( cant by bits) costs around $200. The fuse 0.60
add to the callout fees and you get some idea of the cost can cost half the value if a $1000 TV The plasma screen hasnt gone so that's always a plus and its rare for the video board and sound module to fail simultaneously. So my bet is the poer supply side and fuse

Howdy,
It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thanks for using FIXYA, big IRISH.

SOURCE: 3 year old Samsung 40 inch LCD TV will not turn on

The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.

After you are sure you have hooked up the receiver to the TV properly and with the proper setting in the menu, if you are still having problems then you need to change the main board (the one with all the jacks on it). You will have to take the back from off the set. You will have to get the number from off the board itself and it should start with BN94-. Do a search on ebay with the part number or go to shop jimmy.com for price and availability. Also try to google search. The board is easy to change just unplug and unscrew from the panel.

Connecting my laptop to my sansui 42" lcd tv via the hdmi cable, i get clear picture but no sound


Does your laptop feed sound through the HDMI connection? You may have to use the HDMI 1 jack on the HDLCD3200. Change the HDMI setting in the audio menu on the tv to DVI and run a seperate audio cord from the laptop to tv. I hope this is helpful

Is there a clicking sound? Unplug the power cord for 20 seconds and see if this helps reset the circuitry. If the clicking continues, go to http://www.fixya.com/support/t722954-samsung_lns4051_dx_makes_clicking. If you can see defective caps on the power board and don't feel comfortable replacing, parts can be ordered at PartStore.com.

Dude, better check your cable and also your TV's power management settings. This might also happen due a issue with the HDMI output of the satellite box.
