SOURCE: 3 YEAR OLD SANYO DP 32746. SHUT ITSELF OFF, CAN NOT TURN BACK ON

If you leave the tv unplugged for 2 days (atleast) then plug it back in and try to turn it on and if it comes on its the power supply board. If it comes back on it will probably shut off between 30min to 4hrs and you would have to unplug it for 2 days again. All the power needs to drain out of the tv. If thats the case take the back pannel off and check the part number out on the internet. Not hard to do becarefull touching things the power supply does store a little bit or shock in it. Good Luck.

Testimonial: "while we did not unplug the set, we let it sit for 2 days and we were able to turn it on by the remote & manually....does that still sound like P/S"

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

I would at this point send it back. It has a year warranty. The problem is most likely the inverter but like I said, return it for a replacement.

Picture red can not fix


Step 1:

The problem you have is the grayscale tracking needs to be reset.
First, This looks like a philips tv. In order to set the grayscale tracking remove the back of the set. There should be rectangular shaped box that is marked screen and focus on it with 6 knobs coming out of it.

Step 2:

NOTE: DO NOT TOUCH ANYTHING INSIDE THE SET-YOU WITH BE SHOCKED! WITH THE TV TURNED ON, WITH THE REMOTE, TURN DOWN THE COLOR TO ZERO. ON THE CONTROLS I PREVIOUSLY MMENTIONED, THERE ARE RED,GREEN AND BLUE ADJUSTMENT POTS.

Step 3:

TRY TURNING DOWN THE RED UNTIL YOU SEE A NORMAL GRAY PICTURE. YOU MAY HAVE TO ADD MORE GREEN OR BLUE AS NEEDED. IF THIS DOESNT LOOK RIGHT ,TURN ALL 3 R.G ANDB ALL THE WAY DOWN, THEN ADJUST THEM UNTIL THE COLOR IS JUST APPEARING ON THE SCREEN, MAKE THE PICTURE AS GRAY AS POSSIBLE. iF THIS DOESNT WORK,YOU WILL NEED A SERVICE PERSON TO REPAIR YOUR TV.

Color in tv is very green you cant tell what suppose to be what i was watching cartoons with kids and the animal that suppose to be red was black i tried adjusting color temp and every thing even resetting...


If your using a tuner for your TV channels and you are using component video cables make sure that the red cable is not plugged into the audio socket. red blue and green cables should all be plugged into the "component" input on the tv not audio.

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

Red picture


I would just call westinghouse and lie saying that you are still under warranty. Everything I have read about their tech support screams poor communication, confusion, and lack of manpower, so it would probably work.

Picture is Gray, does not show any color


Are you using component cables (red/green/blue)? Check your connections to see that they are all seated properly. When using component cables, if only the green is plugged in, it will give you a black and white picture. You will get color once you plug in the red and blue.

What kind of sources are you using? what kind of cables are you using? Need these kinds of specifics to ehlp you out.
