My tv, when plugged in just keeps turning itself on and off in intervals of about 3 seconds. It doesn't give time for anything to come up on the screen at all.


Problem is in standby power supply or microprocessor area---not the do it yourself repair and likely not economical to repair due to age and brand of set.

Power problem


would require some troubleshooting, common problems would be convergence amp ic and high volt transformer transistors

NO POWER TO TV


This sounds like a bad convergence board.
You didn't mention the model but I bet its a samsung rear projection HDTV.
If the convergence board fails, you can diagnose by pulling the power leads to the 3 convergence circuits, then power on the tv, if it lights (picture will have very bad convergence) then that is most likely the cause.
You can usually buy a new convergence board for about $80-$100. Look on eBay by the make and model of the TV.
And its real easy to replace.

Panasonic rear projection TV 47 in PT 47WX49


i have the same model and this happened to my set 1 day after yours! i am sending it out for repair on monday so i can let u know what was done and what it cost. i found this: from repairfaq.org:Power-on tick-tick-tick or click-click-click but no other action A variety of power supply or startup problems can result in this or similar behavior. Possibilities include: Lack of startup horizontal drive - see the section: Startup problems - nothing happens, click, or tick-tick-tick sound. The main regulator is cycling on overvoltage due to lack of load. Excessive load or faulty power supply cycling on its overcurrent protection circuit. High voltage shutdown, or some other system detecting an out of regulation condition. However, in this case, there should be some indication that the deflection and HV is attempting to come up - momentary whine, static on the screen, etc. A dried up main filter capacitor or other filter capacitor in the low voltage power supply that is producing an out-of-regulation condition until it warms up. A bad filter capacitor on the output of a series regulator may result in excessive voltage and subsequent shutdown. A problem with the microcontroller, relay or its driver, or standby power supply. One possible test would be to vary the line voltage and observe the set's behavior. It may work fine at one extreme (usually low) or the other. This might give clues as to what is wrong.
