PLEASE WAIT message on screen


The only time I have seen this is when the set is in the "auto program" mode. Once completed, this should not show up again unless the set has been unplugged for a long period of time. Does this show up each time you turn on the set?

My Bush DTR is displaying 'FAIL' on the display, and is stuck on standby. I've tried unplugging for a couple of hours and plugging it back in, but it just show 'PLS WAIT' for a few seconds, before showing...


Hi,
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care in solving the problem.......

Tv turns on screen displays Please Wait then goes black


There's a problem with the power board communicating properly with the interface board aka 'main board'. There's seems to be a logic problem here _Data-Bus interference. This could be because of DC voltage shut down or an under-voltage condition on the power supply board. Also the serial data too and from the Timing control board could also cause a similar problem. You can send the power board and interface board too me and I'll repair the problem for you. Or if you have some test equipment I can show you what to test.

Get back too me when you can.


Please rate this answer :-)

My LC-26sh12u takes 10 minutes to


I had a similar problem where it displays "PLEASE WAIT" for several seconds alternating with blocky colors for several seconds and continuing anywhere from 5 to 30 minutes.

I inferred from a couple of sources that the TV is booting up when it says "please wait" by reading data from flash memory. I was able to fix my problem by resetting the data in memory to factory default values using this procedure from the service manual (wait until the TV is working before trying this):

Turn on the POWER.
Set the VOLUME to minimum.
Press both VOL. DOWN button on the set and Channel button (1) on the remote control for more than 2 seconds.
After the finishing of the initializing of shipping, the unit will turn off automatically

PLASMA DISPLAY STARTING UP. PLEASE WAIT


Un plug the power to the Plasma Screen and also to the Media Receiver for ten minutes. Disconnect the off the air antennas both A and B. After ten minutes plug in the plasma screen then the media receiver and turn on wi the remote control. You should now be back in operation. I was.
Also It may not be a bad digital tuner. The TV Guide feature is active even when the zip code is set to all 0s so if you have an over the air antenna attached the TV will look for the TV Guide info and if it can not find it because of a weak signal or the chanel it is tuned to does not carry that information the TV thinks that tuner does not work which triggers the 12 flashes. Also on power up the gray box with the waring message "Plasma Display Starting Up, Please Wait" appears and the screen is blank.
