Backlight panel or backlight inverter? If the backlight is not coming on the first thing you should replace is the backlight inverter. Panel will cost you as much as a new set if not more. It costs a whopping 1247$

The bottom third of the tv is darker than the rest. It is like a light bar burned out. The tv is 3 years old and has had this problem for 6 months now. Can this be fixed?

Hello There,

It looks more like one of the LCD matrix controller connectors got loose or the chip went out for good. I'd open the case to verify for back light on the bottom portion behind the screen; If you see back light, then check for a loose connector in that area, if no loose connectors are apparent, then the matrix controller is bad. You are in for a new TV set.

What kind of capacitors work best for a power switch on a Samsung LNT-4042 lcd tv? Thank You!

What do mean by the capactiors for the power switch. Electrolytics Caps for the switching power supply should be rated at 105c and low ESR which is a must for switching mode power supply. Digikey sells PANASONIC FM or FC series.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Please see my basic troubleshooting guide here:

Please post back what you find.

The problem is most likely in the image processor area, or the backplane circuitry on the screen itself.
The service rep would be equipped to properly service your set. You should call LG to find out who in your area is able to service your set.
If the set is out of warranty it could be fairly expensive to service.

NEED MANUAL FOR SAMSUNG MODEL LNT 1953H LCD 19'' of the product and related issues:

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

..more specifications from that site + related comments:

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

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).

Email me back for more info:

LN 4661F -won't turn on -clicks -red dot flash

The capacitors in the samsung 4661 are inferior, this happens to all the ones in this line.

If you are feeling handy and don't want to replace your circuit board, here's what you can do.
Remove the 30 screws on the back of the tv. and the plastic shell will lift off.
There are two boxes, a large almost square one to the left (thats the power board, with the bulging capacitors) and a slightly smaller one to the right. (thats the cpu and circuit board)
You only care about the power board for now.

Remove the 6 or 7 screws from the metal casing on the left.
To unplug the connectors, either press your fingers at the sides of the connectors and gently lift them off, or pinch them from the small tab in front, and lift them gently off.
Remove the metal casing.
Unscrew the 5 or 6 screws holding down the power board and lift off the power board and take it to any monitor repair shop and ask them to replace your capacitors on this board, with more powerful ones. (usually 16v instead of the low 10v that come with it)
Just tell them its the samsung LNT-4661F and they will know the problem as most people who own this TV have called them.
Or they can google samsung 4661 capacitor kit, to see what capacitors they want to install.

Hope that helps someone, as I had to do it.
But it saved for $400.

Under menu, option make sure that you haven't selected audion only and that input select is on the first or second options,(not the third one). If you can't even see the menu, then your connections are probably bad. Hope this helps, Mark
