Technosonic stb2009 working fine until last night when the picture froze and the sound went off. Changed channels only to find that all channels are blank, did a reinstall only to be told to check my aerial connection as no channels selected did this and reinstalled but get the same message, any ideas or do I have to get another box?

That is the part that contains the tuner.

sounds like someone rolled over on the remote. if you have cable or a dish, the tv channel must be left on a specific station at all times. no matter what channel is on the cable, the television itself must be on the correct channel number in order to receive he signal from the cable company. try hitting the last channel recall button on the tv, not the cable. otherwise try channel 3 or 4 or sometimes 60 on the tv. good luck

Have you checked the SCART leads?
Usually seems to be the cause of this kind of thing.

ask the remote code search engine, they will get it:

press mute button on tv remote

Like your computer a tv has the same type of circuits, & sometimes they get glitches, maybe, but i feel you might be starting to have a problem in the 'DMD" board in your tv. Maybe not; unplug tv for 10 min to 24 hrs. I am a mit factory auth tech. good luck,.

ysus pcb that supplies voltage to the panel is faulty

• adjust brightness setting when playing tv.
• adjust screen control located on flyback transformer.
• hope this will help.

sounds like it may be a software upgrade
