No Picture on hd channel

[pompey01]

Hi Can anyone help, i have just had virgin media installed and i have a sharp lc32-p55e television which is hd ready. I have connected the the cables correctly ie scart from v+ box and hdmi cable from V+ box to my tv, when switched to hd channel and i switch my tv to ext 5 which is the hdmi channel all i get is audio no piture. The V+ box is set to hdmi wide and 720p output. i believe my tv is capable o9f recieving 1080 as when the v+ box is switched to that my tv says that when initially switched to the channel it comes up with 1080p 50hz but no picture only audio. Help

Your Sharp TV is not HD Ready its panel is 540x 920. It will not support 720p or 1080i inputs. This is why you get sound only. Change the output of the V+ to 576i on the HDMI it should then work and whilst I think you will see the HD chanels they will not be displayed in HD.

Hi THanks for the info but i bought this tv as it said it was hd ready. Apart from that i dont seem to be able to reduce the hdmi on my v+ box below 720p. I have to say i feel a bit ****** off as the tv cost £700 about 18mths ago. My ps 3 plays through the tv ok.

According to this site your tv is HD ready Sharp LC32P55E Lcd Tv

Disconnect the scart and try with just the HDMI connected,box to tv,then switch tv to HDMI input,if you have more than one input make sure you select the right one ....does it work now ?

As an aside didn't the Virgin engineer check to see if the HDMI input was working when he installed the box ?

According to this site (Sharp UK) its not.

Also search the LCD Televisions Forum on here for Sharp P55 and read the threads there. It is reportedly very good for SD though!

Edit:- To get your TV to work at 576i over the HDMI set the V+ box to widescreen scart RGB , connect via HDMI and remove the scart cable...

Sharp LC32P55E/ 32" Widescreen LCD TV

Manufacturer's Description:

Targeting the large swathe of the UK public who are looking to buy a flat panel television for the first time, the LC-32P55E 32" LCD Television is one of the world's first LCD TV specifically designed for the standard UK broadcast PAL signal.
Customers simply wanting a flat panel TV with great picture quality from the existing PAL signal should look further than the LC-32P55E 32" LCD Television. Until now the only choice has been between the awkward compromises of a VGA (640 x 480) resolution set which strips out some of the signal's lines, or a WXGA (1366 x 768) screen which uses processing circuitry to interpolate the extra lines required.

Neither is fully satisfactory, but no flat panel manufacturer has ever solved the problem by manufacturing a screen which reproduces a PAL signal perfectly until now. Sharp's series of Aquos LCD TVs is the only flat panel television range designed solely for the European market, with its 960 x 540 resolution reproducing a PAL broadcast exactly, line for line*.

This gives picture quality at least as good as CRT, with a natural, ultra-low noise image outperforming many LCD and plasma televisions costing significantly more. Whether it's fed a standard analogue terrestrial, Freeview, digital satellite or cable broadcast signal or a DVD source, the results are consistently outstanding.

In addition to its suitability for the PAL signal, the LC-32P55E is future-proofed for upcoming HDTV broadcasts, featuring an HDMI input with HDCP. High definition performance is impressive, with a straightforward half or three-quarter downscale conversion from 1080i or 720p signals to 540 lines. It also has two SCART, Component, S-Video and Video inputs for connection to a wide variety of sources.

The LCD panel also incorporates Sharp's unique Advanced Super View (ASV) technology to enhance picture quality still further, with brightness at 450cd/m2 and a contrast ratio of 800:1. A response time of 12ms ensures there's no smearing when watching fast-moving images such as sport, whilst the viewing angle is 170°, both horizontally and vertically, so everyone has a great view, wherever they may be sitting. In addition, Advanced Optical Picture Control (OPC) automatically adjusts the brightness of the picture to take account of the ambient light in the room.

With Features such as Quick Shoot Technology which improves the response rate to 12msecs and OPC (Optical Picture Control) this new Aquos model really is the New Generation of Flat Panel Displays.

The LC-32P55E is stunningly designed with a brushed silver finish above and below the screen and a contrasting black frame to either side. They make a stylish, space-saving replacement for a CRT, and can also be wall-hung using standard VESA specification bracketry.

* PAL has 625 lines in total. 576 lines carry the picture (the others holding information such as Teletext), but due to 'overscan', where non-essential picture information is broadcast at the edge of the screen to compensate for varying screen specifications, 540 horizontal lines has been chosen as the ideal display resolution.

It basically downconverts the signal to fit the panel. TVs that do this are no longer allowed to be classed as HD because of EU consumer legislation and clearer definitions of what exactly HD TV is.

The TV should still be able to show either 1080i or 720p though, but not at its original resolution???

Amazon Review:

This TV looks great running a normal low def signal such as broadcast tv and dvd, however due to the resolution it is far from HD ready.
At a push you can say it is hd compatible as you can display HD sources on it however the signal has to be downscaled to 'fit' the TV's 540 lines, making the fact that the signal is a high resolution near pointless.

In essence, if you aren't fussed about HD this is a great buy else go for the higher resolution titanium range.

But as I read it the TV does not do the downscaling -something else has to do it. As I say there is a lot of discussion of these Sharp models dating back to 2006 in the LCD TV forum on here and the impression I get from reading some of those threads is that it does not accept 1080i or 720p input. Also the manual makes no mention of these input capabilities.

Irrespective it would be intersting to confirm that the OP's TV will accept 576i over HDMI, if it doesn't then perhaps there is something wrong with either the V+HDMI output, the cable, or the HDMI socket on his TV. It would be interesting if he could borrow another device that outputs at 720p over HDMI e.g. XBOX PSP3 upscaling DVD etc.

Hi have read all your comments and thanks for that just for info though my ps3 does play ok through the hdmi connection. Is this not a case of misleading as i understood this tv was capable of showing hd and it is obviously not.

[pompey01]

Have just tried changing the virgin box to widescreen output rgb and still only get audio no picture.

Hi what output setting does your PS3 use over HDMI? Is it 720p?

What does your TV say on its HDMI input when you switched to Widescreen RGB?

If it says 576i and there is sound but no picture then either the cable or V+ box is faulty.

I agree that you appear to have been somewhat mis-led over the specification of this LCD.

[pompey01]

Hi when i turn to ext 5 my hdmi channel the tv indicates that it is recieving an 576i signal. Still only audio no picture. My ps transmits a signal output of 576i which the tv indicates when my ps 3 is playing through ext 5 and i have no problems with that. So it looks that maybe there is something wrong with virgin although i have changed the hdmi cable to the one i use with my ps3 and that is just the same only audio and virgin have been on site and changed my box and still the same problem occurs. i dont know which way to turn at the moment.

Hello again

Firstly if VM have changed the box why did they not set it up for you and test the HDMI output?

Have you tried the PS3 at a higher resolution than 576i to see how your TV responds?

Sudden thought .... Which V+ box have you got? Scientific Atlanta or Samsung?

[pompey01]

Hi havent tried the ps 3 at a higher resolution yet but will do as for the V+ box it is a SAmsung. Seems to me the installers just want to get in and get out as quickly as poosible, also believe most of them dont know what their doing.

The info regarding setting HDMI to 576i relates to the Scientific Atlanta box. The Samsung is a relatively new introduction and not many of us on here have it yet. It may behave difefrently in some respects to the old SA box.

Will be interested to hear however how the PS3 at higher res works.

Have you tried connecting the PS3 to the HDMI input that you want to use for the V+, it might be the TV input that is faulty.
