    We are having the same problem. It started out with the screen coming on dim and flickering and is now to the point where it refuses to come on even if I turn it on & off several times (with a 10-30 sec. pause) and then after being left alone for and hour or so suddenly comes on like nothing ever happened. Must be gremlins!!!!!!!!!!

Hello
I am a technician-informatic. I have repaired about 80 Lcd Samsung monitors with theese problems. I offer the repair manual.
Manual has been done with the experience of the repairing Samsung Lcd monitors. Manual was made by me and shows how to open monitor, how
to solve dark screen problem, how to check and replace capacitors, how to solve the problem non-optimal mode (without reprogramming MCU or
changing the main board) photo are included. 100% functional. The repair process is very simple 30-40min. (does not need a lot of
experience in electronics and expensive instruments) and is not expensive. With this manual you can solve problems by yourself and save
money.

"Not Optimum Mode 1280x1024 60Hz"
- The monitor turns on but turns off by itself, the LED blinks green.
- If you detach from the PC points to "control cable" the picture runs continuously in the vertical direction or presents while line , and
as soon as it is reconnected, the monitor goes off.
- The monitor does not turns on and dont dispaly anything, the LED blinks green-lit, if you detach from pc points to "control cable".
- The monitor turns on, works well some time, but after a window apiers "Not optimum mode. Mode recommended 1280X1024 60Hz"
- The monitor turns on, works well only with low resolution 800x600, when try to change a window that reads "Not optimum mode. Mode
recommended 1280X1024 60Hz"

the manual you can find on ebay (my ebay name is asnerejas123):

The fault is the backlight, Samsung has designed it as when one of the baklights are faulty the unit shuts down.

Replaced bulb but tv comes only comes on for about 10 to 15 seconds then shuts down and red light flashes


It sounds like you have a bad ballast board, or possibly the power supply going to the ballast bulb. I'm afraid that if you do not have the repair experience on solid state TV sets, you will need to contact and authorized Mitsubishi repair center. Good Luck

My Onkyo 808 shuts down when i raise the volume, and when I try to set it up using the micophone.


Amps shut down in most cases because the receiver is detecting and impedance (below 4 ohms) that might damage the amplifier. Do a quick check of the speaker connection and look for wires that might be shorted to the frame or have crossed each other. This is the most common cause of the unit shutting down. Check your speakers impedance if you have a meter. If you don't then unplug power from the unit and then un-hook all speaker wires from the receiver. Next connect just one speaker (Front Left) and power the unit back on and take the volume up. If it shuts down then try the Front right all by itself, bring the volume up again. If the unit seems ok then add one speaker at a time and test. Continue until you find the bad speaker/cable. Your amp should be able to drive speakers down to 4 ohms. The NR808 has power monitoring (sometimes called crowbar) that looks for to much current and then shuts down. I suspect you may have a short in a cable or in a speaker. The 808 is a great amp and hopefully your problem is external. If your amp continues to shut down even with just one speaker connected then one or more of your channel amps (internal) is likley bad causing the unit to shut down. Good Luck.

There are instructions to replace the lamp in the user's manual. The light comes up but if the lamp has now already several hours of use the resistance of the lamp increases and shut down the power supply of the lamp. Second, the lamp power supply could be bad too, but lets be optimistic and just replace the lamp first.

Reciever Shutting Down


I replaced R916 with a 10 ohm wire wound resister and that fixed the problem on the unit I have. That resister is in serise with R 915 so they should be close in value. Both were marked 8 ohms but tested about 11 ohms on R915 and the bad one tested very high (over 1 meg) so I replaced it. When I first put it back together it didn't work but I noticed that the ground screw at EP901 was not retighted so be sure that all ground screws are tight and all conections are redone before testing with the power cord.

Good Luck,

Thomas
