Question about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV

1 Answer

No signal on main tuner

All of a sudden, there is no signal found using the main tuner. I did an autoscan, and no analog or digital channels are found. I can get a few channels on the PIP tuner if I split the screen. I had been using a cable card from Comcast, but removing it did not make any difference. I am now using the TV component inputs with an external cable box and it works fine as a monitor. Any ideas? Thanks!

Re: No signal on main tuner

Can you connect comcast to another tv that should tell you if it's the tv tuner or cable company.

My rca hd52w58 on autoscan will only find 4hannels MY Visio fines 38 suspect digital tuner any suggeationas?

Could be a tuner but a simple way to find out is DIRECT ENTER with the remote (numbers) a channel and hit enter---if it goes to missing channel you can manually in the menu with the remote ADD each missing channel one at a time--tedious but will rule the tuner out.

Almost every set made is able to add or delete channels one at a time.

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 or for the direction of local transmitters. 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.)

Cable in my area has switched to digital cable. I own a Hitachi HDTV about four years old. When I scan my channels it will only scan analog channels...the digital channels are an option but I don't...

Unfortunately, you need a set-top box. The Hitachi 65F59 has an ATSC (digital OTA) and NTSC (analog) tuner. It doesn't have a clear-QAM (unencrypted digital cable) tuner.

There are a few DVR set-top boxes with QAM tuners that you can buy separately. (You will need to make sure a given model is compatible with your service. FIOS uses a different option on the Cable Card than other providers.) Alternatively, you can get a cable box from your company.

Retrevo has the manual for this Hitachi TV here: . You will need to enter a code to access the PDF.

If you want OTA HD, you will need to determine the correct antenna for your area and the direction to the transmitters. (External antennas pick up more stations. In some areas amplification may be needed to get a good signal.) See or for searches on the appropriate antenna to get a signal and where to point the antenna. Antennaweb assumes an external antenna but is very conservative in the received channel list. You would need to set the TV signal input to Air and rescan for channels if you choose to go with the OTA signal.

I wish that I had better news for you.

Is the PT50LC13 a digital TV? I didn't buy a converter box thinking that the TV didn't need one, but over time and unable to see any channel even with one, I wonder if the TV is indeed digital or not. I...

This tv only has an analog tuner (NTSC). That is why it works with cable and dvds. You will need a converter box to view OTA signals. (In addition, digital signals have a firm cut-off of signal strength; if the tuner doesn't get enough signal the channel will not be available.) So check with or for details on the antenna direction for your area channels. antennaweb is very conservative in the channel listing it provides (even with the assumption of an external antenna). tvfool gives the color specifications of the antenna that should receive a given set of channels in your area.

The converter boxes are still available from select vendors but the government coupons program is not. Here's one that is listed as in stock: . This is one of the standard definition output boxes. High Definition digital to analog converters also exist but are more expensive.

A cheap alternative may be to use a PC TV tuner (either USB or internal card) attached to the antenna and then output to the TV. This TV has a VGA port. (If you want to use component video in on the TV, you will need to check if your video card will support the non-RGB signal or a converter box for that.)

I wish that I could be of more help.

No digital channels

This TV is not able to understand digital channels because its tuner is not able to find that band, it works only in analog channels. To be able to get HD channels is needed a decoder box that has digital tuner build in. for a tv to understand HD Channels with analog tuner is to us to try to speak at the same time different languages.

Cant program digital channels.

Nothing. Digital Tuners Broke. I wouldn't be suprised if your TV freezes up momentarily (or for a long time) when you switch over to the Digital Channels.

This TV has 1 tuner for analog channels and 1 tuner for digital channels. You can probably find the Digital Tuner on Ebay and replace it.

I have 50" PF9966 flat TV , not sure if is HD ready ? 2006 model how do i find out , nothing showing in guide

There are a few things to consider here. First, if you are using cable or satelite, the changeover has no effect on you anyway. If you are using an antenna, the changeover to a digital broadcast signal has already been in place for a while. The set should be able to auto-detect these signals. I believe that most of the models from 2005 on had digital signal tuners available. This is not the same as a "digital" tuner. A digital tuner only means that the stations are tuned digitally but are still analog signals. The changeover will be to change the analog signals to digital ones that require a smaller frequesny band for broadcast thus opening up more space for additional channels.

Hope this helps,
