Question about Philips Magnavox 51MP392H Rear Projection Television

1 Answer

Magnavox 55'' Projection - Sides come in and out

When I first turn it on for about 20 minutes the sides cycle in and out, about 1 per second, about 6 inches in. Oddly, it especially happens with white or light images, but a dark image will stop it. After about 20 minutes of use, it stops. I'm guessing it is some sort of power supply regulator, or convergence issue.

Sounds like Convergence issue.... I have some pictures of the bowing picture TV on the link below...

I'll post you my general message which is for a similar Philips Magnavox 51 inch TV, you'll need to check the manual verify the correct IC convergence chips and resistors, the manual link is below as well... usally the IC's are STK392-120's or 150's and the resistors are 6.8 ohm 12 of then...

anyway read the general post below it will get you headed in the right direction.

51MP392H/17

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted
pictures on, check out page 3

Not Ready for Smog test


it is not how many miles but the type of driving.

here is a OBD2 drive cycle test.

Generic OBD II "Drive Cycle" Most OBD II ("On-Board Diagnostics II") diagnostic monitors will run at some time during normal operation of the vehicle.
However, to satisy all of the different Trip enable criteria and run all of the OBD II diagnostic monitors, the vehicle must be driven under a variety of conditions. The following drive cycle will (theoretically) allow all monitors to run on (??) vehicle. (Note: Drive cycle specifics vary by vehicle!)
  1. Ensure that the fuel tank is between 1/4 and 3/4 full.
  2. Start cold (below 86°F /30°C) and warm up until engine coolant temperature is at least 160° F (typically requires at least one minute; up to 3 minutes).
  3. Accelerate to 40-55 MPH at 25% throttle and maintain speed for five minutes.
  4. Decelerate without using the brake (coast down) to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.
  5. Restart and accelerate to 40-55 MPH at 25% throttle and maintain speed for two minutes.
  6. Decelerate with using the brake [or the clutch!] by coasting down to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.

You have to re-set the obd via using Nissan's approved drive-cycle which is;

1. Start the engine when the engine coolant

temperature gauge needle points to C. Allow

the engine to idle until the gauge needle

points between the C and H (normal operating

temperature).

2. Accelerate the vehicle to 55 MPH (88

km/h), then quickly release the accelerator

pedal completely and keep it released for at

least 6 seconds.

3. Quickly depress the accelerator pedal for a

moment, then drive the vehicle at a speed

of 53 to 60 MPH (86 to 96 km/h) for at least

5 minutes.

4. Stop the vehicle.

5. Accelerate the vehicle to 35 MPH (55 km/h)

and maintain the speed for 20 seconds.

6. Repeat steps 4 through 5 at least 3 times.

7. Accelerate the vehicle to 55 MPH (88 km/h)

and maintain the speed for at least 3 minutes.

8. Stop the vehicle and turn the engine off.

9. Repeat steps 1 through 8 at least one more

time.

If step 1 through 7 is interrupted, repeat the

preceding step. Any safe driving mode is acceptable

between steps. Do not stop the engine

until step 7 is completed. If you cannot or

do not want to perform the driving pattern, a
NISSAN dealer can conduct it for you.

Turning off by itself


This TV probably needs the convergence amp IC's replaced. When they go bad the TV will not turn on.Call a good TV Tech and tell him you want the IC's upgraded to STK 392-150 instead of the original STK 392-120 and check all resistors in the circuit for proper value. They could be burned or open.
