Question about Sony KP-48S75 48" Rear Projection Television

1 Answer

Sony model KP-41T65 no power, smoking

I have a 1998 projection that worked fine until now. The screen had color bands momentarily and went off completely. Looking inside, it is smoking at C514 - a small round component. It does this as soon as the set is plugged in - without having to turn on the power. Having experience with electronics, can someone give instructions on what this is and what parts/steps are neeed for me to repair it? I don't want to haul it to a repair shop to have them charge hundreds for a 10 year old set. Thanks

    Same problem that ashbeth has. Looks like some type of small round possibly blue diode has burnt inside the set

    Having the same problem as ashbeth. It looks like a small round possibly blue diode has burnt on the power cord side of the circuit board about half way towards the front of the TV.

Hello All,

The component you are talking about is not a diode, it is a capacitor, and if it is burning it has shorted, which means that it needs to be replaced. You will need a schematic and a multimeter. Now since you all thought that this component was anything but a capacitor, I would not suggest that you attempt repairs on your own, because this section is dangerous, and can kill you if you are not careful. I would suggest that all of you get a qualified TV technician to examine your sets and affect repairs on it.

I hope this helps,
Thank you,

Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.

You can get more information and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

kindly advise please.

TV smokes when you turn it on and no picture

Check to see where the smoke is comming from, the far left side of the unit, it is probably the flyback/horizontal output transformer. The big gray/black thing on the board with the two red wires out of the top of it.Replace the horizontal output transistor (D2348) with a new one to increase reliability. It is the large three leged transistor to the left of the transformer. Use Sony parts if possible.
