Panasonic rear projection TV 47 in PT 47WX49

I started watching tv tonight and all of a sudden the tv just turned off. The red light went out and just turned itself off. I unplugged it and it came back on for a second then went out again. I have very little money and can't afford a new one. Please let me know if this can be fixed and if it is expensive. I am very mechanically inclined. Thank you. Keith

Re: Panasonic rear projection TV 47 in PT 47WX49

Camaroguy: This exact problem happened to us about 8 months ago. A board had to be replaced at a cost of $500. Yesterday, the convergence has gone on the set. You get a blue and yellow shadow on the picture. From what I have been reading, this has happened on a few TVs and it will cost another $500 or so. We refuse to pour more money down the drain so we just went out and bought a new plasma (RCA) for half what it cost us for the Panasonic 4 years ago. We have never had a problem with RCA in the past (two tvs for 20 years a piece).

I have a pt-47wxc43g panasonic projection tv and when i turn it on the red light blinks three times and it does not turn on.

Three times red light blinking indicates problem of convergence output chips are bad, tv has 2 chips that need to be replaced.
Let me know if you are handy with electronics stuff repair and can replace/ solder parts in circuit board to provide you technical info OR local tv repairman will do this job for you.

Our tv suddenly began showing what looks like a rainbow on the bottom third of the screen (last evening). Tonight, it is even more pronounced. What's going on?

You need to replace the convergence ICs they are both STK392-110 you can get replacement ICs at the following link and they provide free installation instructions.

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 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.
