    Same problem. LED on front indicates red when plugged in, green when powered on. But no channels display and no output to TV.

    Anyone know a solution?

Troubleshooting switching power supplies just sucks, but there are ways of finding the fautly componets. In my case, a visual inspection found 2 bad capitors, the tops bulging open and oosing goo. If you look at the tops of any other caps they should be flat. You can also note faulty caps by discoloration of the circiut board itself. I had one other faulty cap on my supply that, by visual inspection had been running hot. After replacing the defective caps (Nichicon 105c) I went with an ohm meter, and checked the smaller transistors for faults. Q1 a very common transistor was bad (2N3906) with a base emitter short. In conclusion, it's the cheap caps that are at fault, sometimes taking the silicon with them as they short out. The unit is now working.
As an added note, I understand that there is a Radio Shack branded version of the HD3150 as well.

LG 17LX1R flashing red LED - TV won't power up


Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

I have a RCA D52W20 rear projection HDTV. This TV was purchased in2005. I cancelled my cable and I just hooked up a digital antenna but the TV isn't finding any channels. What do I need to do? I was...


HDTV indicates the number of lines that are shown by the TV. (HD means that at least 720 lines can be displayed in a given picture.) To receive OTA signals, you need an ATSC tuner (digital) of sufficient power (with a clear path to the transmitter) these days. The RCA D52W20 was released in 2002 and only has an NTSC (analog tuner). You will need a digital-to-analog converter to receive OTA TV (unless any low power analog stations remain in your area).

Please note that the basic digital-to-analog converters that were available with the government coupon back in 2009 were SD (480i lines of pixels used) units. HD d-t-a converters exist but are more expensive.

I hope this helps.

(the phrase "digital antenna" is meaningless; check with tvfool.com or antennaweb.org for the direction of local transmitters. TVfool.com will give more information on the type of antenna (indoor, outdoor, amplifier) that you will need to receive channels in your area. Antennaweb assumes an external antenna but is very conservative in the stations that it will indicate that you can receive. Antennas are given a color rating based on how far away the transmitter can be to get a watchable signal. Since digital signals are either enough for the tuner to interpret or you get a "no signal" message, you often need a stronger signal than was needed to receive a watchable analog channel.)

So you are telling me I need a digital converter for this TV to g


Who was not watching the months of public service announcements? You need a Digital-to-Analog (ATSC-to-NTSC) converter box to receive over-the-air (OTA) signals in most parts of the country. You do not need one for most cable and satellite box outputs--they are NTSC or HDMI. Some low-power, typically religious, stations are still analog. Note OTA may be high definition (HD) or standard resolution (SD) but will be digital.
To get HD on your HD set you must have OTA (HD TV tuner, not converter), cable (QAM TV receiver), satellite (HDMI or 5-wire RCA),or Blu-Ray with HDMI or RCA.

I don't know how a program it, since you change digital.


So far as I know the HLN series does not have an ATSC tuner, thus no over the air (OTA) reception. You can probably still get a $40 coupon for an OTA ATSC to NTSC converter. Note that will NOT get you high definition (HD). With Dish you can get HD receivers that do get OTA ATSC both HD and SD. With Direct, no OTA AFAIK. With cable you would need a QAM tuner, not in your TV AFAIK to get clear channels as required for locals. Otherwise cable needs a Set Top Box for digital and scrambled channels although the standard definition (SD) non-scrambled channels work with your NTSC tuner. Too bad there seem to be no ATSC to 5-cable RCA or HDMI HD converters except Dish. -Ken

Today was the HD switch..I get nothing on my HDTV?


This wound be due to a bad tuner and nothing else. Speacially with those pop's in the audioCheck and see if your still under warrentee if not give www.teexp.com a try they will work with the manufacture so you can get some of the cost down in the repair. Now OTA signals is diffrent then cable/sat so please check and make sure when your scanning for OTA that its see on antenna if it is and your still hearing pop's the tuner is gone.

Your TV is an "HD-Ready" television. What this means is that your TV is ready to accept HD input from an outside source, but doesn't have the ability to produce the content itself. It is a monitor and does not have a digital tuner. Without a digital tuner (or for cable a QAM tuner) you will not receive OTA broadcast HD.

You need to purchase a High Definition capable set-top converter box. The converter box will have HD component out and may have HDMI out, either will feed your HD Ready TV.

No OTA channels


This television has an extremely weak tuner. It is very sensitive to both ghosting (multipath) and weak signal conditions, which cause it's digital decoder to "error out". Coupled with this is the decoder's long set-up time (time to actually begin a decoded video stream after signal is selected)and you find that every time the decoder loses sync it takes several seconds to reestablish normal decoding. The net result is the possiblity that the tuner will be continually restarting and never display anything. An extremely directional antenna may help. Otherwise, find a good external tuner box and use that.

Problems with subtly changing colors


What connection are you using, HDMI or component?

Also, on what source is the problem happening, through sat or through off air antenna?

If you're on HDMI I'd try component. Then, playback the affected video and see if it's reproduced w/ component.

If it's on ota only, you may have a loose tuner cable inside. It's easy to fix, you need a torx t-10 screwdriver. Unplug the unit, take the 5 torx screws off of the back cover, and on the right side you'll see 2 cables running from tuners in the front to a splitter that connects to the tuner for ota on the back right. Just make sure the connections are tight with your hands only, don't over tighten them. Also, make sure you don't touch the power supply when you have the unit open!
