Question about Panasonic PT-47WX42 47" Rear Projection Television

1 Answer

Bad Component Good day all: I've had my 47" TV for about four years and just recently the tv would power up for a few seconds then shut off. The power indicator light on the front panel would then blink three times. After leaving the tv unplugged for two days I got up the nerve to pop the back off and take a peak inside. Nothing really stood out as the culprit so I plugged the set back in and had my wife hit the power button, what I noticed was a capacitor glowing like a christmas tree light then the set shut off. This capacitor is the first of many in a row next to the convergence amplifier, it's grey in color with one band and is in the shape of a resistor. Most notable was the incredible amount of dust that collected on the pc board, I vacuumed it all out and labeled the wire harnesses and removed the whole chasis from the set. My question to the tech guys//// has anyone heard of this before? Could it just be a simple cap that burned out and I could bring the chasis to a repair shop and get a new one? Or is there a deeper more sinister reason why just this cap would let go? Any help would be appreciated, hopefully this is low cost fix and maybe help others with a similar problem. Cheers: Lee

Re: Bad Component

Hello Lee. I have seen that many, many times. There are 2 large black convergence IC's, STK392-110 and one of them has shorted out. The extra current it is drawing is cooking the resistor next to it and the computer senses the extra current and shuts the set down. The part you see glowing is a 2.2 ohm 1 watt (or 2 watt)resistor, the same as the 5 other resistors next to it colored red, red, gold. You need to replace the convergence IC that the burning resistor is connected to and replace that resistor, and your set will then work normally again. If you have no experience replacing convergence IC's then have a qualified tech handle it for you.

Is your girlfriend's television higher resolution? If so, the ps3 may be configured to output a signal that is too high for your mitsubishi. With the ps3 off, insert either the component or the rgb to the back. The turn on the main ps3 power switch so that the red led turns on. then hold down the 'power on' button. it will beep initially, then beep after about 3 seconds. This simply resets the output to the connected cable in a normal resolution.

SD Tech I replaced both convergence chips with two news one. Now with TV on table when I turn it on the projection lights do not come on and the TV shuts down in a few seconds. jaybirdwv

there is still a component problem in the t.v. send it back to the tech. if the convergence chips have failed again, the power supply circuit should be checked.

When i power up the tv, it immediately shuts off

How old is the tv? Sounds like the bulb. Is there any kind of lamp light indicator blinking or on? Averager life of a bulb is a few years, but could very well be shortened. Also check any surge protectors you might have. Maybe you recently had a surge and it needs to be reset. Last but not least try recycling the power on the tv. Unplug for 10 seconds then plug back in. happens a lot with cable boxes, recievers, and tv's from time to time.

Projection TV keeps shutting down

Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.
