The tuner and or the IF sections in the TV are going defective, or there is a power supply distribution fault that is effecting the TV's front end. One or both modules, or a board may need to be changed.

Take the set to the Philips authorized service to verfiy and fault and have an estimate.

Tv works fine,cut it off and it will not come back on . Red light blinks 6 times, then repeats itself.


this is an indication of a overcurrent/ overvoltage error....meaning short in a voltage supply. I have seen this problem in the shop with this set. IN MY CASE it was shorted convergence chips. but it could also be any of the low voltage supplies 5,10 15,-15 lines

Usually this happens to my set when I am in HD cable channel mode after being on a non-digital ANALOG channel.

I basically reset the TV by changing to a DIGITAL cable channel -- stay on that channel for ten-twenty seconds -- then I switch back DIRECTLY to a HD channel (key in channel number directly on remote).

TV works fine -- seems to be a glitch when the TV changes modes from Analog to HD

Can't change TV to CATV mode


You must unplug the cable connecting the television and the cable box. Then turn the television off and then back on. Do not turn the cable box off or disconnect the cable in wire from the cable box especially if you use Cable Vision. It will take up to 20 minutes before the box comes back on. Now turn the television back on. When you access the Channel System menu, you have the access to the submenu choices. Change the Antenna option to CATV and the Current Channel to 3. Reconnect the cable box to the TV.

Also those that are having problems with the TV turning off periodically, make sure the sleep mode option does not have a number in it. For example, if the number is 10, it will turn off every 10 minutes.

No sound on analog channels


Grab your sharp remote and press MENU, arrow over to SETUP, arrow down to RESET and press enter and follow that prompt to reset the unit. Once that is complete turn the tv off and unplug ONLY the tv for one minute then plug it back in. Then turn the tv on and see if you have channels, if you do, your audio should work on you analog stations, if you have no channels and all you see is a snowy picture do the following press MENU, arrow over to SETUP...arrow down to CH SETUP and press ENTER...you will then be at a screen that says AIR/CABLE, press ENTER, select CABLE or CABLE(STD) if that option is available to you. after then, arrow down to CH SEARCH, press ENTER, then you should be highlighted on ANALOG AND DIGITAL SEARCH...press ENTER and wait for 15-30 minutes ( or until you get a picture back) and make sure you DO NOT press any buttons or turn the tv off and you should be good. good luck 2 u

I need help now


Have you tried turning your cable box off, given it 3 minutes then turn it back on. We have Time Warner Cable and their remote has the tv and cable buttons at the top right of it and sometimes that helps. Good luck

Channel set


Apparently your TV is set to the "standard TV" position. Before you auto program your set, set it to the cable mode and then do the autoprogramming. In the standard TV setting, you just get off the air channels 2-13 vhf and 14-83 uhf.where as in the cable mode you get vhf channels 2-13 plus your cable channels. Stargazer
