Question about Sony VAIO VGN-SZ330P/B Notebook

1 Answer

I had to open the Vaio VGN SZ13 to repair a broken case screw, I also fixed the inverter but now that I have done it all and closed it up all works fine again except the sound?! I have no error message, the sound icon is showing all is ok but absolutely no sound now comes out of the speakers, only via headphones....I checked all I could find on the net but if someone knows something I don't it would be much appreciated.

You ARE using an ESD wrist strap, and have it's alligator clip attached to a good ground source, correct?

Otherwise you are going to Static shock your laptop, and can use it for a Doorstop.
(Or conversation piece,
"Hey what's that Stewart?" "Oh that was an attempt to repair an old VAIO I had." )

Average price is around $3 to $6. One example,

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
You can also set a large metal serving tray (Unpainted), on the TABLE you are working on, and connect to it.
Or a large metal knickknack (Unpainted)

Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
(You can use a clean egg carton if you need to)

SOME screws look VERY similar to other screws.
Advise DO NOT mix them up.
(Especially since there is no free Service Manual)

Let's look at some of the casing parts, to familiarize you,

Get the Sony part number off of the Touchpad, to look up a replacement.

How do i replace the backlight on my sony vgn-fj1s


It's much easier to just replace the screen than trying to replace the back light. Save yourself the trouble and buy a new screen on ebay.

I think I have broken my headphone jack on my sony vaio VGN-CS320J because headphones plugged into this jack do not work, unless held at a certain angle, otherwise sound continues to come from the laptop...


It might be the plug on the headphone that's bad - try it on another laptop. If it's the jack that's bad, then it will need to be taken apart and that's not easy to fix - recommend having a repair shop fix it.

Sony Vaio Display problem


Hi,

Since the Sony Vaio VGN-CR220E works except that the display is dark, then it would be safe to assume that it is only the LCD display part that is the issue. Often LCD display (of laptops) are working but only that you can not see the actual display. One way to verify is to shine a flashlight at an oblique angle to the screen, semblance or part of the desktop could be seen s what you have done. If the desktop could be seen (albeit very very dark background) then it could either be the CCF Lamps (cold cathode florescent) or the inverter that powers the lamps.

Often, the defective component would be the inverter. It is relatively easy to replace the inverted. It is sometimes more difficult and challenging cracking open the casing of the display panel of the laptop than replacing the inverter. Additionally, inverters are readily available online. It is also not surprising that inverters for other brands/models would also be used in your Sony Vaio VGN-CR220E .

Of course another possibility is that there is just a loose connection or a cold solder in the LCD panel display's circuit boards.

This would be a good place to start for inverter boards. This is a nice tutorial if you are considering a DIY.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

VGN-TX850P/B Display Problem


Hello Frank,

This is Romeet, id like to try and help you.Most Sony's have a small circuit at the front end of the LCD that effectively works like an Inverter Circuit.How good are you at opening these things up? any electronic repair centre near you? has to be a problem with the fusible resistor or inductor on the circuit i mentioned ( as mostly seen in my experience ).Please let me know.
