Problem solved. inside this computer there are a set of dip switches a block of 4 top middle of circuit board, 1 up 3down, what i did was to switch all switches to the the up posistion, and not having a clue what would happen.

Ureka the computer came on, if you switch of and switch on again comp becomes operative at once, depending how long you leave it off the longer it takes to come on.

Example if it is switched off say overnight it will take about 2.5 mins to come on, it seem that the comp is doing some sought of self checking. I could play around with those dip switches but as it is now working and i understand what is happening (I think) i will leave well alone.

My Technika LCD32-229 is just over 12 months old and has suddenly decided not to respond to the remote or on/off control on the TV. If I turn of the power at the mains for 30 seconds or so, it will then...


HERE'S THE ANSWER TO YOUR PROBLEM:

The possible reason why your TV doesn't respond to your remote is probably the battery of your remote. Maybe it has been used up to it's fullest capacity, so try checking it up. In case, it has been used up, try to buy a new one.

The possible reason why your TV doesn't stay on is still your remote control. Maybe you have accidentally set it to "sleep mode." When it is set into sleep mode, it turns on just for a shorter time. It cannot stay on longer.

So, here's what you've got to do. Check your remote. When the remote works already, press the sleep button remote again. I hope it works for you.

Thanks.

TX-47F430S seems to be the common problem of going back into standby. Powers up shows the logs and then goes back to low power. The light never goes blue. The fiber optical laser turns on and stays on but...


This is known as SLEEP MODE / STANDY MODE problem.

Simple solutions:
1. Get a power surge protector / strip.
2. Plug your TV power cord to the power surge.
3.Then turn-on your TV using the remote control2_bing.gif. Just in case it won't go all the way to normal state.
4. Turn-off the switch of your power surge like 5 times with an interval of 3-5 seconds.
5. Then repeat step 3 and 4.
6. These steps are done to over-ride the sleep mode.
