Question about RCA L37WD12 37 in. LCD HDTV

1 Answer

I am having a problem with RCA L37WD12 37 Inch HDTV LCD TV...when I plug it in the red light comes on but when I either push the on button or remote the red light blinks, and turns off and nothing else happens. Some times the it stays lit for 3 seconds and then turns off. I have looked inside and replaced a couple of capaciters, but still the same results. Thanks.. Tim Mcneil tmacii2000@yahoo.com

It is the capacitors on the power supply...They blew on ours...took it in a they replaced 7 for less than 100.00. Common problem with this tv because it gets hot. Hope that helps.

You may have dying power supply module, that will be the first place to check.

SOURCE: RCA L26WD12 26IN, LCD TV will not turn on, the red

It can be due to unstable DC power from the power supply due to bad caps, or bad main board (I had to replace my main board, and later on the inverter boards). You may want to think about putting money into this TV.

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

I have no remote for an rca l32wd22 hdtv lcd tv and cannot find the inputs to change to HDMI?


Unfortunately, the L32WD22 doesn't have an Input button on the front panel of the TV. You need a remote control that matches the Input code for the remote. Here's one link to a remote that should work: http://remotes.com/store/rca/l32wd22.html . Other universal remotes may work if you find the correct code if the remote has an Input or Source button.

I hope this helps.

Can't hook vcr to tv


on the back of your VCR there will be a yellow colored port - most likely labeled "OUT" as well as possibly a white/red pair of ports.
The yellow is for a VIDEO hookup, the white and red are for AUDIO hookups.
These ports use what is called an RCA type connection.
Radio Shack, or just about any department store should be able to sell you an inexpensive set of RCA cables.

now on the back of the TV (possibly on the side) you will also have the yellow, white and red ports.

Hook one end of the RCA cable to the colored ports on the VCR, the other end of the cable to the colored ports on the TV.

last thing - the TV most likely has multiple inputs. there is probably a input button on the TVs remote, you need to press that button to cycle through the inputs until you get to the one the VCR is hooked up to.
its easiest to put a tape in the VCR and press play - when you get to the right input, you will see your tape...

good luck

Can't get my dish network remote to work with my new 32 inch RCA LCD TV tried the codes in manuel for dish remote


I contacted RCA and they said that the tv won't work with most universal remotes because the IR signal used is "new technology." They said that newer universal remotes may work with it.

Personally, I think it's great to push new technologies, but not so smart to push it onto devices that are being sold at Walmart. I went to Walmart for a deal, and I don't want to spend $150 on a remote that will work with that "deal" I bought.

Philips universal remote codes


For the majority of phillips/magnavox universal remotes: Hold code search button down till red light satys on. Press the tv button and the red light should blink and stay lit. With the tv on, push the power button repeatedly until the tv turns off.(dont push the power button again after the tv turns off or it will go to the next code). Push the mute button to save the setting.
