My Sanyo HT28745 28" HDTV clicks but doesn't turn on
When the power button on the front of the unit gets pressed, it makes a couple clicking noises but won't turn on. No sound comes out and nothing appears on the screen. Any advice on how this problem can be fixed as well as cost?

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.

TV shutting off automatically means its a problem with the Lamp. Contact Pioneer or any local tech shop or Best buy and get the same replaced. Turning off after specific time : Go to the timer option and disable the Automatically Switch off option. This will resolve the issue. Please let me know if it worked.

tv wont turn on when i hit power it makes the clicking noise like it is going to turn on, but never does and the red timer light next to the power button just flashes. help! trinitron kv29f1u only clicks and blinks
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. Self-diagnosis error 2-3 indicating deflection failure. Check for shorted or leaky Q5A37 part # 260P818050 located on PCB-Main. If found defective replace only the transistor instead of the Main PCB.
If you forget your password you can reset it. Make sure the TV is off. Simultaneously press and hold VOL< on the TV?s front panel and CLEAR on the remote for approximately 5 seconds. Enter a new password next time you access the PARENTAL CONTROL menu.
Front Panel Lock
1. From the PARENTAL CONTROL menu, press the up or down arrow to highlight Lock Fr. Panel.
2. Press the right or left arrow to turn on (box has check mark) or off (box doesn?t have check mark) front panel lock.
Of course if you don't have a remote that can bring up the menu I don't know how this can be done.
I have the same problem-still troubleshooting...so far still not find the cause. DM1 power supply output voltages are operates correctly. Signal output of microprocessor up and down (no good) that turn on Q14105 and latch optical isolator U14102 to power the unit but both of ohmed out ok. it hard to troubleshoot the main board with power on.
