This is usually caused by failing capacitors in the pin amp section. Testing caps with an ESR meter is a good way to find the failed caps. Or, you can do it by replacing the caps by guessing. Or, you can use a scope and follow up for the proper waveforms.

While you are working on the set, it would be best to verify the caps in the power supply and scan amplifiers.

If the fault is more complicated than just caps, you will probably require the service manual and have to spend the time to troublshoot the pin amp circuits.

It is attached to the trunk support panel, directly behind the trunk lid hinge. It may be easier to get to by taking out the rear seat back cushon.

Check its "Pin-cushion" section circuit for the fault. An IC is used there to control the pin cushion distortion. If this IC has got faulty, this type of fault can occur. This is actually a skilled work. If you are not ahndy, seek any technicians' support.

How do I keep my samsung ln46c550j1f in wide screen picture size? Every time I switch it to wide screen it turns back 16.9 screen size every hour or so.

Your TV is set to "Store Demo Mode", this means people can play with them in the shop and it always returns back to a normal picture every hour or so. Here's how to fix it :)
Press Source - select TV.
Press Menu - Select the Setup menu (its the picture of the cog on the left 4th picture down)
Select "Plug and Play"... the default pin is 0 0 0 0
Select your language
Make sure "HOME USE" has a yellow box around it.
Select your country.
Scan in your channels if you need to?
Fixed :)
By the way... I have the same tv ;)

No picture in upper half of screen, normal at bottom

Could be something as simple as a bad contact on one of the deflection yokes or other coils on the cathode ray tube - check the contacts on the circuit board where these coils are connected, resolder the pins or wires if the contact is bad, also check connector pins for any dirt or oxydation and clean if necessary.

Sony kp-51hw40 both of my pin cushons need to be replaced. am i able to replace them myself?

Try to find your model's service manual on the sony site here:

You can also google for the manual. The service manual, not to be confused with the owner/user guide, tells you how to replace parts and perform maintenance.

This link has the instructions on how to fix other similar problems. You have nothing to lose, so I recommend that you try it.

This works with the two other colors, blue and green also. Not all models of Sony Projection TVs have the red, green, and blue pots in the same order as the picture that is listed on this link, so you may want to google search for your model's service manual. The service manual can also help you be able to remove the cover for your particular model of TV. I was able to find the service manual for my model, and sure enough, the order of the pots are reversed on mine, so I would have been adjusting the wrong color. Read all of the comments on this link too, because you can find other helpful tips and may even find someone with the same model of TV as you.

I hope this helps you!
Fare well. :)

Whoopie cushon/balloon noise

Try disconnecting the air intake and see what happens (that won't harm the engine). I don't believe it will harm the engine w/ this noise, although it might be a little embarrassing. They have been using corn to make gasoline, I wonder if they started using beans?
Let me know the results and any new clues you may think of or the truck may develop. Have someone under the hood when u shut truck off to see it they can figure exactly where it's coming from. Beano in the gas tank? No, No, don't do that. countrycurt0

Top and Bottom curve on a Phillips rear projection hdtv monitor

I cannot tell you locations for parts in this model, but this fault is genericaly very much the same for all CRT sets.

There is a fault in the pin cushoning circuits. Usually this is from failing electrolytic caps in that area. The pin amp is also part of the vert and horiz deflection circuits. Sometimes the pin amp driver devices (IC's or transistors) can also be at fault.

With an ESR meter it is very easy to find the defective caps. They will have higher than normal ESR than the caps that are working properly.

If the barrel distortion is along the width of the display, this indicates that the pin fault is in the vertical pinn part of the pinn circuits.

32" TV Screen Problem

This is a pin cushoning fault. The failure is in the pin amp, and also most likely in the scan amplifier sections. The scan amps and pin amp in part of their functions work together to control the paralax of the picture scanning. They also control the dynamic focus.

To service this, you will need the training, service information, the testing tools, parts availability, and the necessary tools to follow up.

These types of faults can be complex to service, and can be a chalenge to even an experienced tech.

Tv screen has slight hourglass shape

A common fault are some of the electrolytic capacitors failing in the pin cushoning amp section, and probably in part of the scan amplifiers.

To service this will require the proper training and set-up to troubleshoot the set.

Take the set to a service center for an estimate. The cost can be at least an hour or two for the labour, and then the cost of the parts on top.
