Question about Panasonic Televison & Video

Open Question

Panasonic CinemaVision PT51HX40B -- Shuts down within a few seconds of power up. If you repeatedly try to power on, smoke rises from a bank of 1/4 W resistors on the main board beneath the left most CRT. Is there a most likely cause for this particular model that would expedite the service process? It sounds like the high voltage is present momentarily (normal static sounds) and low voltage is evidenced by glowing of the CRT filaments just before shutdown.

Most projections have a removable speaker cover on the front under the screen. Then there is an access panel that you remove the CRT sockets are the circuit boards attached to the CRTs

SOURCE: no raster, no sound on 53UWX10B

double check the wire connections, as the filaments not being lit makes me thing a wire isnt connected properly, or one may have been loosend while doing the convergence repairs.

3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures.

Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

I have a Panasonic cinemavision HD TV rear projection. It turns on and then shuts off as soon as the picture comes up. Can this be fixed?


Almost anything can be fixed.

When it shuts off does the power light on the front blink in a sequence like 3 or 5 blinks then pause and repeat?

Bad color then no power on 51'' panasonic cinemavision


Check the power light for blink code--usually if this model shuts down the power light will blink in a sequence--3 blinks a pause and 3 blinks is short protection--usually means a convergence circuit problem.

TV powers up initially, but shuts down within seconds.


These TV's are somewhat sensitive to internal heat. It appears your sensor has triggered an overheat. This doesnt mean you still have the heat issue, it just saying it needs to be replaced or reset, either way it is not something you can do in your home. Taking it to your local authorized shop will ensure proper repairs, about $90 worth.

Panasonic Cinemavision 53" Projection 2002


TV's have a circuit in them that monitors the high-voltage and shuts the set down if it senses something amiss. On a projection type set, figure on just replacing the entire board that has the flyback transformer on it.
