Question about RCA F36450 36" TV

1 Answer

Horizontal size The horizontal size on the screen needs to be adjusted, How do I accompliosh this. I have the Howard Sams photofact service manual # 4825 and it has some miscellaneous adjustments one is called the horizonal size so I entered into the servive menu and adjusted that particular setting and it did not affect the picture at all. Does the horizontal size have something to do with the Gemstar 4 module? could it be defective?

Which service manual setting controls horizontal size?

You're discussing about the factory mode adjustments. The horizontal width adjustments will not be there. You have to adjust it by replacing certain capacitors at the horizontal output stage.

Flyback no. 25gt539

Try Suburban Electronics as they sell generic replacements for these older RCA and GE sets---If you need the part number look for a Howard W. Sams Photofact for this set, has schematics and a complete parts list included.

RCA 20F514TD has lost horizontal hold. How can I adjust this? I have found no button or menu option discussed in the manual or by searching.

Horizontal rolling is the fault to your TV I assumes. It is a circuit fault. It can't be adjusted by customer controls. Contact any experienced service technician.

I have a jvc modle av-27920 that will not come on

This model should be covered by the Howard Sams Photofacts---you can buy one for it online with the model number--many large library's have them in archive as well.

3 burnt means a problem in that area which is why you want the schematic as well.

Samsung txe2546, how to adjust horizontal size. I went on the service mode but there is no adjustement for horizontal size. How can I adjust it, because the image is larger than the screen... Thank you...

Hello Laurent
This is pretty easy it's like when you adjust the imgae on your pc monitor, go to the menu then go to settings, select video or image, look for the option and just change it there.
