Sharp LC37X20E - No Digital reception.

Hi folks,

Have one where it scans but finds nothing. First replaced the lower board with the tuner - Same. Then replaced the upper board with the HDMI sockets - Same again.

Confused (But have the service manual) - Chris.

Supply OK and ripple free? Only  common denominator here?

Here's the user manual if any good? http://www.sharp-cee.com/cps/rde/xbcr/documents/documents/om/11_lcd-tv/LC32X20E-S-37X20E-S_OM_GB.pdf

Hi Dave,

Have the service manual and have had lots of fun trying update via USB - It won't update. Pressing/holding channel down and input while turning on get only a flashing Green led which will flash for ever.
Trying get into service mode gets no 'K' so suspect it's a panel fault as set works well using Scart input, though with HDMI inputs OSG states input wrong format on two of the three sockets and the other the picture jumps about a bit.
Suspect I have a duff top (HDMI sockets) panel via Ebay so trying for another, though they're hen's teeth at a decent price - The lower board with the tuner is real cheap, possibly for good reasons - Chris.

Davy:
Did you see page 8 of the user manual about supplying power to the antenna?

Supplying power to the antenna
You must supply power to the antenna in order to receive digitally/terrestrially broadcast stations after connecting the antenna cable to the antenna input terminal on the back of your TV.

1. Press MENU and the menu screen displays.
2. Press c/d to select “Setup”.
3. Press a/b to select “Antenna Setup-DIGITAL”, and then press OK.
4. Press a/b to select “Supply Voltage”, and then press OK.
5. Press c/d to select “On”, and then press OK.

Never had to do all that before!

Reminds me when I went to Sharp on their video recorders course when they first came out..... they had very naughty words on the PCB part numbers - if I tell ya' here I'll sure to get banned.

Hi Dave, Nice one,

Recall going to a Philips G500 course way back, Instructing chap liked a glass so we had a great time of an evening in Mitcham.

Have ever suspected that Philips stuff gets you that way.

Off the point, of course. My Antenna doesn't need a DC supply as it comes through a masthead amp, a distribution amp in the house loft and another distribution amp in the workshop.

Not a lover of amplifiers, but my house is the other side of a thick wood from 'Tacolneston' the local transmitter. Reception is sometimes a bit corrupt, but I know how corrupt it's liable to be and suggest folks do a re-scan to pick up any missing channels - Chris.
