Question about RCA L37WD12 37 in. LCD HDTV

Blinking screen and clicking noise

I have a RCA tv and dvd player combo. When i went to turn on the TV last night it began to blink a couple of times with a clicking noise following it. It happens every couple of minutes. I tried to unhook the cable cords and unplug the tv thinking it might be the cause but it continues to do it. The tv is only a year old and I have no idea why it is doing this. If anyone can help me while trying to not go towards the inevitable of buying a new tv it would be much appreciated. Thank you.

The TV is on protect mode. The clicking sound is the protection switch that keep turning the TV off to prevent further damage, this happens when a fault had been detected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

How do I make tv cut on and stop black screen


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

I bought at Toshiba HD TV/DVD combo 26" in January and last night the picture went totally white and makes a loud, fast ticking noise. Is it toast?


White screen means that the T-CON is nothing getting the 12vdc from the logic main board or the fuse on the T-CON board has blown. But first place to check will always be the power supply module first. Not sure about the clicking sound, DVD section?

I turned on the tv last night and it worked for a few minuets then it went out. I unplugged the tv and then back in and I do not even get the red light on the Tv to show up?


It sounds like a power surge might of ruin one of your boards. How old is your TV, what brand, model. Always use a surge protector as the electric company will not take any responsibility. Try turning off the unit again and unplugging it. Leave it unplugged for at least 3-6 hours, this will give it enough time to discharge. Plug it back it. Turn it on, what do you see or hear. Do you hear a high pitch noise if only for a second or two. Do you see a pin light at the center of the screen for a second or two. Your tube could have went bad. It cost to much to repair TV's these days. If it is not under warranty. Consider looking on craigslist, there are some great deals on there. Hope this helps, let me know if I can help you further.
