Question about RCA L37WD12 37 in. LCD HDTV

1 Answer

RCA L37WD12 screen goes blank & power light goes off

TV all of a sudden turns itself off yet the power is still on. Power light goes from red to green when turned on, and then without notice the screen just goes black and the power light goes out (no green or red). Pushing tv power button off will then switch the tv to off and the power button returns to red.Problem was infrequent when it started a few months ago but now it happens all the time and is very frustrating. Initially you could simply turn the power off and then on and tv would come back on after one or two attempts. Now the tv will take 10-15 attempts to come back on--however, it now goes back off in less than a minute. The TV is not quite 2 years old.Any idea what might be causing the problem?

SOURCE: Need a power supply for RCA L37wd12

This power supply might not be manufactured anymore or the only place to find it is by calling RCA but that is a pricey board. You can also check this website and ask them if they have one. It appears like they do not have stock but you can call them just in case they have not updated the site.
I can also help you in repairing the defective power supply if you still have it. Write to jah2mil@hotmail.com if you need further assistance.

SOURCE: Power light stays red and nothing comes on on my

I just had my Vizio which blew up and the power light stayed on and you could not turn it off on the tv you had to unplug it and then when you plug it back in same thing all over again, no picture at all , My TV made a loud pop before this happened, paid 1700 for TV and repairs were 900, bought new TV instead, never buy a Visio, there customer service totally sucks, you get a warranty and they try to screw you with an old piece of junk refurbished TV, they tried anyway, after 2 months they finally gave me my money back and I bought a totally awesome, SAMSUMG, THE WAY TO GO!! It sounds like the same deal and if it is a Visio just do a google search and see how many people it has happened to that own a visio..steve

SOURCE: Power Light is On, TV is blank.

reallyme07, sounds like a "thermally intermittant solder joint" on one of the circuit boards (switch-mode-power-supply / inverter-supply) that are a key component used to light up the "cold-cathode-fluorescent-tubes" that supply "WHITE LIGHT" to illuminate the LCD panel. you didn't state what you would like to do or how to get it repaired?? Do you have warranty on set? how old is it? The same technology is used in small screen LCD computer monitors. you may want to visit YOUTUBE and search for and view the longer video clips of LCD monitor disassembly and repair videos FYI. The same kind of problems exist for them as do your lcdhdtv. In any case, a tech type person will need to fix it by an IN-HOME VISIT or CARRY-IN to the shop. I'm louie12fix on fixya or lmistyrel@aol.com Please rate this response if possible. Bye for now.

When turning on tv. screen will display Bravia image & then go blank. red light flashes SIX times


Power off the television. Wait a few minutes, then power it back on. If this does not correct the issue leave the power on, point your remote control towards the Sony television and hold the down arrow button. While holding the down arrow button press the "Power" button. Release the down arrow button and the Sony TVicon1.png will reset itself to factory settings. Once the television performs a scan on itself your problem should be gone.
Good Luck Ed Pinero
