More information is required to properly troubleshoot this problem. How is your television connected when you are watching HD? Do you have HDMI for this, do you have a satellite or digital cable box? For analogue are you using regular coax antenna (cable TV), or are you going through a cable or satellite box?
This could be related to the aspect ration setting. perhaps you ahve changed your aspect ratio from 16:9 to 4:3 or some other setting. If you are connected via HDMI, then the digital signal may be "normalizing" your picture during HD, but reverting back to the other setting.

Check you video settings very carefully. HD televisions are very difficult to tweak properly.

SOURCE: 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.

SOURCE: how do I scan the channels on a Panasonic 1080i

The cable to the antenna and another cable from the TV needed to be hooked up and THEN follow the directions that came along with the converter box.
Channel 3/4 and scan., be sure the antenna is strong enough.

There was no need to touch the DVD/VCR box.

SOURCE: This set has green plaid screen on all analog

This is the digital board causing the problem, so replace that board or try this - the problem may be connections on the DNIE chip on the digital board, near the DVI connector at the back side of the board. Apply pressure to this chip. It is a BGA type (Ball Grid Array) that has pins underneath that contact points on the board. This is becoming common with high density ICs where external pin connections require larger size chips, tighter spacing, and geometries that are not efficient for the design of the chip. There are good reasons to use BGA, but they can be difficult to solder properly. Apparently, Samsung has had some issues with this chip. One solution is to try to re-flow the solder. I don't suggest this for anyone without the right equipment or trechnical expertise. It is very easy to heat the wrong parts or overheat the chip, board, or related parts. The board is encased in a metal housing with holes. Look for something that might fit between the chip and housing to put some pressure on the chip. A small bolt might fit between the chip and the metal housing above it. Fit it in, then push the edges of the housing down to where you can put the screws holding it all together back in. There will be significant tension on the bolt, with the larger hex head end standing on the chip and the tip of the screw fitting against the metal housing (bolt standing on its head on top of the chip). It will take a little pressure to get the screws back in, which is good, as it will use the housing like a large spring pushing down on the bolt, which will put a great deal of pressure on the chip. Simple solution if this is the problem.

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: http://www.retrevo.com/support/Hitachi-65F59-TVs-manual/id/371ci977/t/2/ . 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 antennaweb.org or tvfool.com 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.

RCA HD52W59 HDTV Plug in digital antenna into air antenna input then run channel scan =0 channels What should I do next??? Mike


Make sure you are connecting the digital antenna to the digital antenna input on the back of the set, then rescan. Most over the air Tv signals migrated to digital transmission and therefore the analog input is mostly for older analog devices. If you still do not get any channels, then you need to make sure the antenna you are using is rated for reception in your area. You can check for proper antenna size and channels available here,http://www.antennaweb.org/aw/welcome.aspx

No analog stations on my hdtv 37 inch, have no digal box just regular cable, regular cable works on normal tv


Try an antenna if you want to get analog over the air. I have a feeling that with the way the standards are changing, you will only be able to get digital channels. After February, the analog channels won't be around.

If you are using cable tv you need an HDTV box to get high def.
