Re: power problems

Something wrong with the power switch? Does it stop if you press any buttons on the TV (including the power button)?

Prior to disassembly, unplug the power plug from the AC outlet without fail. (Turn the power "off".) Short the SB connector [1] pin and [2] pin of the DIGITAL INPUT MODULE PWB. (At the time of assembling) Before the rear cover is inserted into the cabinet,release the short-circuit between the SB connector [1]pin and [2]pin of the DIGITAL INPUT MODULE PWB. After releasing the short-circuit between the SB connectors, do not turn the power on until the rear cover is inserted into the cabinet. Negligence in carrying out the above steps may cause the inactivation of the TV.

Tv turns on and off

My JVC 35 " AV 35750 toggled on/off non-stop too.

Fix for me: Unplug TV. Trace cables from on/off switch to main circuit board. I unplugged the cable at that point to eliminate the the on/off button and remote control sensor. Applied power to the TV and my TV stopped cycling on/off so I figured the problem was probably not on the main circuit board but with the push button/ remote control sensor board. I again removed power from the TV and plugged the cable back in to the main circuit board. I then applied power back to my TV to verify my symptom, but when I did this, the TV worked fine again.

Many times resetting circuit board connectors will clear electrical problems.

TV won't turn on

The set is in protective shutdown because a problem was detected. The 5 blink code indicates that the problem circuit. In this case it is the blanking circuit. Were there any indications of problems prior to the storm? If not, I'll need to lok up this one for the specifics. Do you intend to repair this yourself?

Let me know and I'll provide the details.

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.

Constant clicking every half-second as soon as you plug it in.

I have the same problem-still 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.
