Change power supply,but screen turn on for 1 second then off


You have to enter its service menu option, and make all suggested adjustmens there, after power board replacement. Download its service manual. Not user manual. It will have all service adjustments.

Bought it in 2008, now it comes on for 90 seconds then goes out. Probably a bad inverter or power supply board. Are parts available for this monitor?


Hello,

Is it the screen that goes blank or the power of the monitor? is the power led button on?

If the power led button is on, and it is the screen that goes off, this indicates that the picture board of your monitor is malfunctioning and will need to be replaced.

But if it is that everything goes off, it means the inverter is bad and will need to be replaced.

For the parts, yes, Being HP is even advantage, because virtually,most service centers do have the parts

Just walk to any hp service or any service center within your vicinity to get them.

Take care

Six years excellent service then the screen went black except during start-up the start-up screen flashed om and off, and remained black through the Windows start. The screen did flash on for a second on...


You may have failed backlight inverter circuits, caps failure in the power supply, or bad lamps. Here is the service manual: http://www.eserviceinfo.com/downloadsm/22184/SONY_SDM-HS73.html
You will need to open it up and take some voltage measurement in the power supply first to make that you do have correct DC voltage feeding the inverter PCBA.

CCA Values For Samsung TV


With the TV off, you need to push

Mute-1-8-2-Power very fast. just wait and it will show up.

If the tv is on press Power-mute-1-8-2-Power and it will show up as well. Good luck, I am still trying to fix the CCA values myself. When you get in the Service Menu, just use the arrows to get around and to get back use the menu key.....

Flat screen doesn't want to come on


The power supply might be defective on your TV and will need to be replace.
I service these power supplies, since there are not many replacement service parts.
Let me know if you need more assistance.

Screen problem


Hi there!
This is where service technicians make finer adjustments and not open to the consumer for adjustments. You need to know what all the settings mean before adjusting(you should not have to). I think the set needs to be reset or the EEProm may have failed because of power surge, in which case you will have to refer to service technician. Every TV uses different software to function. Good Luck, JUS004

My Sanyo HT28745 28" HDTV clicks but doesn't turn on


I have had a similar problem with my tv, it has something to do with the power supply.Try unplugging your tv from the AC outlet. While unplugged from the power supply hold down the - volume control and then plug the tv back in while holding down the - volume control. It should bring up the service screen. If the screen turns on and is blank then it may need to be brought in for repairs.

If the screen does turn on, either blank or with the service menu, turn off the tv and unplug it from the power supply again. With it still unplugged hold down the power button on the tv and then replug in the tv. continue to hold down the power button until the tv displays a video signal on screen.
