Re: Sony KDL 40WL135 showing Double image
Thanks for the PDF file. Read through it. I will open the set tomarrow and we'll see if there's anything else wrong with it.
I 'll up date everyone after I figure out more.
From what I read that looks like it will be the problem.

Sony KDL 40WL135 showing Double image
Hey Everybody,
Was given a Sony KDL 40 WL135 to see if I could repair. What I see first is when I power it up a double image on the Screen. Some what distorted.
Would this have anything to do with the T-con or maybe the Convergance
Convergance being the X and Y Haven't opened it up yet thought I 'd do that this weekend. I'll include some photos. Anybody have this simular problem? That I can read up on. Thanks!... -
Re: Westinghouse SK-32H240S - blue light, wont turn on
Thought I'd add to this post. I have this model and here's what I've been told.
On the main power supply circuit board you should see 3 inverter transformers, (look like little gray bars.) These are nortious for going bad. My unit would turn on and then there would be no picture and no sound. My set now has a cracked screen due to shipping with UPS which looks like a spider web accrossed it. But again I'm told this is usually the case with this t.V.Last edited by Dblueman; 02-03-2013, 07:12 PM.Leave a comment:

Re: NEC Px42VM3A lost all display
the 4 white resistors that show G5W 4.7 ohm Micro 1DT are reading only 3.6
these are up by the 1500uf 200V capLeave a comment:

I am greatful for the help. I know it is difficult when you don't have the PSU in front of you.Leave a comment:

Re: NEC Px42VM3A lost all display
nothing with that marking on the top. All I see is something simular that has 4R7 (there are 2 of these) and 1 that says 2R2Leave a comment:

Re: NEC Px42VM3A lost all display
RC1 the diode with 2 pins taken out of circuit board reads as follows
+ on left - on right reads 1
+ on right - on left reads 616
RC2 the diode with 3 pins taken out of the circuit board reads as follows
+ on left pin 1 - on pin 2 reads 171
+ on left pin 2 - on pin 3 reads 1
+ on pin 3 - on pin 2 reads 164
+ on pin 2 - on pin 1 reads 1Leave a comment:

Re: NEC Px42VM3A lost all display
if you mean on RC1 which has 2 pins putting + lead on left and - on right and then switching them putting + on right and -on left it reads as follows
677 switching them it reads 547
as for RC2 which has 3 pins putting + lead on left and - on right it reads as follows
606 (+ on pin 1 and - on pin2) (+ on pin 2 and - on pin3) reads 1
(+ on pin3 and - on pin2) reads 606 ( + on pin2 and - on pin1) reads 1Leave a comment:

Re: NEC Px42VM3A lost all display
what do you mean by both ways?Leave a comment:

Re: NEC Px42VM3A lost all display
RC2 which has 3 pins reads 608 and RC1 which reads 678Leave a comment:

Re: NEC Px42VM3A lost all display
If I am correct the diodes are as follows 1 is behind the 4 white lets call them blocksnext to the heat sink and the other one is by a lone hwite box to the right of the 1500 uf 200V cap. Each of these reads 755 and 770Leave a comment:

Re: NEC Px42VM3A lost all display
can you show me which ones and do I need to remove them from the circuit boardLeave a comment:

Re: NEC Px42VM3A lost all display
there's a label next to the PSU (Power Supply Unit) on the left. But not on the PSU itself but on the let call it the sheet which the PSU is attached too. This has 4 gold screws which hold it in. on that label is the following
42NH-PDP-4
S/N 02214262
Input AC 100-240v 50Hz/60Hz 5.4A
Output +170V 1.6A,+60V 1.6A, +5V, 4.0A,+5V,0.8A, + 3.3V 1.8A
