20 Most Recent RCA L26W11 26 in. HD-Ready LCD Television Questions & Answers

Hello Bruno,
These LCD's were manufactured in or around 2006 or early 2007. Service parts are hard to find or not available.
I would suggest to invest in a new TV instead of fixing this one. If you intend to DIY, check the link to see if they might be able to help you find parts or know where to find them.
Let me know if you would need further assistance.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Check its main power supply regulator section circuit for defective component/s. Contact any service technician.

Most likely place to start checking is the power supply board or the inverter board if they are discrete boards.

Check fuses, they will be in the vicinity of where power enters the board(s) Then look for bulging capacitors- if you find any, replace with comparable values of same or slightly higher working voltage. And replace all in the vicnity of the failed caps. Use high ripple current types as the General purpose types you might buy at Radio Shack are just General Purpose and they do differ internally.

If those check out, or have been replaced and set still not functional, Look for resistors or diodes that are discolored (they may have failed). The power resistors are a good place to start as some double as fuses whether designed to or not.

If the set has a logged a few thousand hours and flickers, or shuts down after image begins to appear, the CCFL tubes are likely at the end of their life span as well.

If you can't find a replacement, you may be able to glue it back together with metal-filled epoxy (J. B. Weld).

It's a backlight or backlight inverter issue. (The backlight itself usually fades or makes the on-screen image change to pink/red.) For an out-of-warranty TV, open up the back of the TV and remove the shielding. Look for any scorch marks or bulging or damaged capacitors. (Sometimes other parts will fail on this part but these can be spotted easily. Capacitors look like cylinders on a tripod.)

If you borrow (or have a) high-end multimeter (able to measure high frequencies - 50 kHz) or an oscilloscope, hold the multimeter probes a fraction of an inch apart about an inch above the board and power up the TV. If you see a 1 or an actual value, you have a good inverter. If you see a reading near 0, the board is bad or the multimeter can't resolve the frequency.

In either case, you can buy a replacement inverter for $50-150 and just do a simple swap. Disconnect all of the wires (connections are similar to molex and ribbon cables in a computer) and remove board (a few screws usually). Connect the cables to the new inverter. (If you google backlight inverter replacement, you'll find videos and text descriptions.) Note the part number on the board, including the Rev number, and order the exact one (shopjimmy.com or lcdparts.net are good starting points). Universal inverters do exist but can result in reversed controls (up to lower the brightness). Replacing individual parts on the board is cheaper but more prone to not tracking down all of the bad parts.

If the inverter is good, then it's probably backlights themselves (several in most TVs). These are sandwiched on the perimeter of the TV (usually under some tape that holds the lamp, reflector and other parts together. You need to order by length and width and get ones for your TV size. Remove the tape, and separate the reflector (make a note of how things are put together) then you have to Dremel (or use another rotary tool) to remove the plastic to get the backlight out. (They are often molded into the frame.) Then put in the new backlight and reassemble everything. (http://www.lcdparts.net/howto/default.aspx for laptops) but for an overview: http://www.inventgeek.com/Projects/BacklightFix/overview.aspx

With a good spare backlight, you can test an inverter for condition (plug together and turn on the tv while the box is open). Similarly a good inverter can test the backlight. With a bad backlight, you'll usually see a very dim image if you look at the TV from an inch from the screen. Block the room light from overwhelming this image (sometimes a carefully positioned flashlight will help you see something). If the inverter or video board is bad, you will see nothing

I hope this helps.

It sounds like the LCD controller board went out, look inside to see if the cable may have come off the LCD controller board. You can look and see what it looks like here: http://www.shopjimmy.com/catalogsearch/result/?q=RCA+L26WD21+
Please post back what you find.

Check to see that the fuse is good. If so, test power supply. It is common for these to go out..
