The problem occurs with backlight on display DVB-TV and the AV, HDMI ...

Yes, you can force the TV to display HDMI by accessing the input selection menu. Here's how to do it:

1. Press the "Input" or "Source" button on your Sharp remote control. This should bring up the input selection menu on the screen.
2. Use the arrow buttons on the remote to select "HDMI" as the input source.
3. Press "OK" or "Enter" to confirm the selection.
4. The TV should now display the HDMI input signal from your device.

If this doesn't work, you may need to check the HDMI cable and make sure it's connected properly. If the cable is damaged or faulty, it can cause issues with the HDMI signal.
Regarding the eeprom problem, it's not recommended to modify the TV's firmware or eeprom unless you're a qualified technician. If you suspect that the TV's firmware is causing the issue, you should contact Sharp customer support or a professional repair service for assistance.

Hi
On my set I just hit the input button 'TV'. By pressing the 'TV' button again causes the TV to toggle between Analogue and digital.
On my Panosonic I have buttons on the remote labelled input, with a sub selection of either AV or TV.

Your resolution on your ps3 may be too high for the tv to display. Hook up your PS3 to you TV with the HDMI cable. Now, when you turn on your PS3, hold the power button on the PS3 for 5 seconds. It will reset the PS3 video options and recognize the HDMI connection. It will then search for the correct resolution settings on the TV. Press (X) to confirm. And that's it. You should be set. If not, then the TV is acting rather strange.

First check your aerial.
If other devices such as PVRs or other TVs can receive a signal then the Sense 51-19 should be OK also

Turn on the TV.
Press the "TV/.AV" button until the letters "DVB" (Digital Video Broadcast) appear on top right of screen.
Wait until patterned blue screen is displayed and the message "No Signal" is shown.
Press "SYS MENU" 3 times
"General Menu" should be displayed with Language option in highlight.
Press the "CH+" button once to move the highlight to the "Reset" option.

Press the "TV/TXT-DVB MENU" (this has the letters "SET" engraved on the button itself.

The TV will mute and a sub-menu will be displayed in the top left of screen.

Use the "CH+" or "CH-" to scroll to the desired option.

Cheers

What is probably happening, is your PS3 is set for the wrong type of output. If you are using an HDMI cord, try switching to the AV cables that came with your PS3, and set your TV at the appropriate input to correspond with the AV hookups, and see if the picture works then.
If you are using the AV cables, it may have been set to HDMI accidentally. You need to use an HDMI cord, and hook the PS3 up to an HDMI compatible TV or monitor, and select the HDMI input. Once you get the picture working, go to Settings>Display Settings and set the display you wish to use.

Sorry your TV is NOT compatibile with DVB-C,DVB-S, DVB-T, or with any other digital technology.
have a nice day

The PlayStation 3 (PS3) is a high-definition gaming console that supports both standard AV connections and high-resolution connections (such as HDMI). Most of the older Philips TVs come with a standard AV input. Newer, flat-panel Philips TVs include standard AV inputs and high-resolution inputs. To get the best video quality out of your PS3, using an HDMI connection is recommended if the option is available. The PS3 does not include an HDMI cable, only a standard AV cable

Standard AV

1 Turn off the PS3.

2 Connect the flat end of the PS3 AV cable into the "AV Multi Out" port on the back of the PS3.

3 Connect the "red," "white" and "yellow" prongs on the opposite end of the PS3 AV cable into the corresponding "red," "white" and "yellow" AV inputs on the TV (usually located on the side or in the back).

4 Press the "Source" button on the Philips TV remote.

5 Select the "AV" video display mode.

6 Turn on the PS3. The PS3 logo will appear on the screen.

HDMI Connection

A quick google search of that model number turns up that tv doesn't have an HDMI port. Your next option would just use component cables instead. At 26 inches you will never notice the difference.

The unit was being manufactured in the early to mid 2000's but I believe is not out of production. It is NOT an HDV. Here are the specs for the TV.
