I AM LOOKING FOR THE SURFACE MOUNTED FUSE ON THE CONTROL BOARD

The problem is no back lights.If the back lights is not working the back lights inverter is the cause of that, there's a blown surface mounted fuses or leak capacitor.So its better to check the back lights inverter board and find the blown surface mounted fuse cause of shorted transistor or transformer.Hope it will help you.Thanks..

Hello,
it possible that the problem is the the TCON board, you can try websites Shopjimmy.com,Ebay.com to buy a refurbish board for the replacement.

Also note that
The T-CON (Timing Control or LCD controller) board (on the LCD panel assembly). It transfer the universal image signal of TTL and LVDS signal to specific TFT (Thin Film Transistor) LCD.
This is the interface board that talks to the Logic board and the LCD panel to produce pictures on the screen. White/gray glowing screen when it fails or not getting the voltage from the logic board (the 5 or 12vdc is supplied by switched transistor on the logic board). Notes: T-CON board is mounted under the metal cover shield.
Common failures:
Scrambled pictures, Lines, multiple pictures, color smears/blotches, rolling pictures after warm up.
Blown surface mounted fuse.
No pictures, very dark screen almost like there is no backlights.
Hope this helpout..

A very common problem w/ this set is a fuse that will open, that is located on the main board(the board w/ the tuner on it). This is a very small surface mounted fuse, it's white in color, and located at the upper right hand corner of the board, if looking at it from the back of the set. The location number is F3 and the fuse is 1.5 amp. I have seen many of these. I would definately start there.

check the power board for faulty caps or surface mounted fuse, check numbers on board eg f103 f is fuse, c123 c is for cap

The overhead display is powered by the same circuit for the overhead console, so if the vanity mirrors still work, chances are the fuse is fine.

Just in case, push the button a few times, to make sure the display is not turned off.
The overhead displays have a chance of the surface mounted resistors becoming unsoldered over time.
You can get one at a junk yard, or if you are good with a soldering iron, you can reattach the surface mounted resistors. Pull the overhead console down, and remove the display ( T10 screws holding the display to the console ). There are 2 plastic tabs holding the display together, release these.
On the back of the circuit board, you are looking for a resistor that looks like this :

The problem can be in the LCD CONTROLLER (T-CON) board. Check to see if you have voltage feeding the board or it may have blown surface mounted fuse on the board.

Try unhooking the LVDS cable from the controller board and see if it does the same thing. If so you need to replace the LCD panel.

There's only one main power fuse, and it's located behind the control board assembly. Once you remove the board, you should see the fuse mounted in it's own clip. They're sometimes mounted on the white plastic bracket housing the door switches.

THis is been an issue with these sets. Rca has issued a bullteen on these sets.. There is a problem with the digital board. you cant get them... but the fix is to replace a small(very very small ) suface mounted fuse on the board... most qualifed tech can do this repair. so if you can solder surface mounted componets ussally takes twezzers and a big lighted magnifer.. and if you can get the special surface mounted fuse(seems to be a shortage of them) Replacement fuse #275819. u might can fix this. repair is possible
