Hello - I have a Sony PCG-252L - All in one, and the display is bad. There's a video toggle switch on the top, near the power button, and when I hit that it turns on for about a second and then turns off. I know the video is onboard, and I'm assuming I'm out of luck - just wondering if there's anything I can do to resuscitate it.
Any ideas? thanks!

I've got a friend with the exact same issue on the same model & have been looking into this for him.

There are basically two options:

(1)  Contact Sony at www.sonyrepairservices.com and set up a repair visit.    You drop the unit at the most convenient Sony store and can pick it up there when done (or you can ship it).    It costs $150 to "evaluate" the unit; and most repairs are under $300.     So basically it will cost you ~ $300 to get it repaired.

(2)  You can disassemble the unit yourself; remove the inverter; and then buy a replacement.    It's ALMOST certain that's the issue -- LCD display issues are virtually always either the backlight or the inverter; and since the display is lighting up just fine when you toggle it, it's not the backlight.    A new inverter will likely cost ~ $50-80.    Disassembly of the rear cover involves first pulling off the cover panel (it's not fastened -- just "pops" off);  and then removing about 2 dozen screws (Be SURE you keep track of these and where they go).

My friend hasn't decided which approach to take, so I haven't taken the unit apart and don't know the exact model # or cost for the inverter.    I've contacted several LCD display repair outfits, but haven't found any that have a good cross reference for the correct part number -- so you'll need the old unit removed to know exactly what to buy.

The PCG-252L is a very nice unit, so I'd definitely get it repaired.   Worst case is $300 ... essentially like buying an expensive replacement monitor.

Great info. I did pop the case off to have a look. Maybe I'll search for a manual to see where the inverter sits - not exactly sure what I'm hunting for. But if I can find it, I'll take it out to get a part number. Maybe that will help persuade your friend as well!

I believe it sits horizontally across the top of the motherboard -- but I have NOT taken the case apart for my friend, so that's just based on looking through the slots with a flashlight.

But if you do get the part #, I'd definitely appreciate it.

The PCG-252L is a very nice unit -- definitely worth even the $300 to repair (although if it was mine I'd certainly do it myself).    My friend is out of town this week, so I won't know for another few days which way he's going to approach this.

As for a manual -- I searched a good bit, but didn't have any luck finding a service manual.    There are several videos available that show how to disassemble it [basically just common sense -- remove all the screws :-) ]

I couldn't find a manual either. Tomorrow I'll see if I can take a decent picture to upload and maybe we can figure it out. thanks!

I found the inverter. The part number is D2038-B001-M2-0 on the circuit board (Brand is NEC/TOKIN) and part number 1-443-889-11 printed on a sticker that sits on a plastic covering of the module.

I just found one for sale on Ebay (UK) for $60, with the same part numbers. The ad states: This inverter is for the dual lamp screen. This inverter is NEW! and is the new more reliable design.

I haven't sourced any here in the states. Maybe this is my only option. $60 seems like a reasonable gamble, I'd think. I've seen other posts from people with the same model with a "white screen" issue. Looks like that is more of a mobo problem...?

I presume this is the link you're referring to:  http://www.ebay.com/itm/NEW-SONY-INVERTER-D2038-B001-M2-0-1-443-889-11-/120744039227

It lists the VGC-LS21N as one of the supported models -- I've found that same model # as a cross-reference for the PCG-252L on several sites, so I presume it's the same unit (I did find a driver for it using that cross-reference when we installed Windows 7 on it, and it worked fine).

I'd agree that $68 (with shipping)  is a very reasonable gamble -- and it's almost certain it will fix the problem.

A "white screen" issue is definitely different -- most likely a problem with the video adapter or memory.

Did the system require any further disassembly to remove the inverter ... or is it readily accessible after you take off the back panel?

Yes, that's the same Ebay link I found.

The module is just glued down on the two ends. I pried one end slowly and it popped off. Pretty easy.

I think I'll go ahead and order that piece and see what happens!

I just got the replacement inverter and installed it. Video is on! I've been running it now for about two hours.

Excellent.    My friend decided to replace it as well, so we have one on the way.   Hopefully with equally good results :-)

I'm sure it will be -- it was a virtually identical problem.

Hello People,
I have this same computer model, Sony Vaio  PCG-252L, all in one computer with the same problem. I will give my customer a quote for the repair. I'll quote him a price of $50 for the inverter board and $69 for labor. Plus his computer running Vista home premium was running very slow. will need virus cleaning, defragging as well.
Seems like this is 99% the problem rather than the lamps being bad too.
How does that quote sound to you guys? I saw some Sony inverters that were pulled from a working laptop/computer going for $16 USD. They had a 30 day return policy.
What do you think about getting a used inverter to make a repair on any lcd monitor/TV?
Thanks for the help.

Jimmy
