Question about Samsung PCL545R 54" Rear Projection Television

1 Answer

Convergence out and turns itself off

I just got one of these sets and it will turn on, but "no signal connected.." is not level across screen and when in the menu you can tell that the RGB guns are not lined up, there is also some vertical bowing of certain colors. I think red is the furthest out of alignment, seems like someone might have messed with adjustments.
Also the set will turn itself off sometimes just whenever, other times it seems to turn off when you run the perfect picture adjustment. I am an ET but have never dealt with a rear projection TV before.
Any ideas what I should check first?

Thanks JB

Objects are doubled and colors are distorted


Projection sets have two very common problems.

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. 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 and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*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

Problem after replacing convergence board


Yes, you do need to set up the convergence in order to get the picture geometry correct. the antenna and maybe some other settings will need to be restored through the appropriate user interface screens. You will need your owners manual for a guide.

Convergence out and turns itself off


This is a convergence problem that should be relatively easy to resolve, I am assuming that the set is new to you rather than new. If new, it should be under warranty and if opened would void the warranty. If new to you and you can solder, you should be able to fix this. First, realize that there are potentially dangerous high voltages present inside the set even when unplugged. Locate the convergence ICs (large black ICs attached to a heatsink and marked STKxxx) and resolder the pins. That may resolve the problem. If not, then replace the ICs. Check the area for small valued resistors that may be defective as well.

Keep us posted.

LINES ACROSS TV


Good Day, YOU ALL;
Try this: 1. E2RESET DOES NOT RESET THE CONVERGENCE. THE CONVERGENCE CAN BE RESET BY PRESSING "MENU 12598970", IF THIS DOES NOT RESET THE CONVERGENCE TRY "MENU 125968970"

2. CHECK C2P08 100 UFD 16 V OFF PIN 3 OF IC2P03 (3.2 VOLT REGULATOR) ON THE SIGNAL PCB.

Also you may poor solder connections on the vertical output IC or on the CONVERGENCE IC's.

Hope this helped, good luck, big IRISH.
