I have the same problem and am attempting to replace the display board myself. Unfortunately I can't seem to get the back cover off. How do you removed the back cover from this TV?

Thanks all for the information and link to the main board.

i was having the exact problem listed in the first post with dots appearing and multiplying in that pattern and growing until the whole screen was a mess.

I followed the link and purchased the main board with the correct part number. The board was 197 and backordered. one month later, the mainboard appeared at my doorstep. But ran into a problem with the back panel removal.

I removed all of the screws on the back panel and was stuck for a while. With the LCD screen down, I slipped a flathead screwdriver (carefully between the black back panel and the silver frame in the lower corner just above the speaker section. Carefully edging the screwdriver down, you will see the edge of the back panel and the snap tab holding it onto the frame. Angle the flat head underneath the black panel <POP> the back panel literally begins to pop off. Remove screws, ground wires (3) etc... described above... ltv_27w2 back in action!!! Thanks all who contributed.!!!

I have a westinghouse LTV -27w2 27in HDTV-ready LCD TV,It will not come on,TV came on once had blue screen,then went off,it will not come back on,has a black screen now,blue light came on then turned...

That could be either the Power supply or the main board. I would think the main board is most likely because of the Blue screen you mentioned.

Hi i have the westinghouse ltv-27w2 it has lines on the screen what internal parts control the picture?

T-CON board, check the connections between the T-CON and the Main LOGIC board first (very rarely to be the logic board but not 100% for sure). Make sure to get the number as printed on the board since there are more than one version. http://www.shopjimmy.com/catalogsearch/result/?q=Westinghouse+LTV-27W2+

No picture

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

I am having problems with my Westinghouse LTV-32w3 HD TV. If flickers and rolls kind of like the old tube tv used to roll and you would have to adjust it in the back by turning the nob. I have a 37 inch...

The LCD controller is bad, after about on for 30 minutes, see sample here: http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/
Notee: my pix show the board with the cover removed. You can run the TV with the back open and have s small fan blowing in the back to keep it cool.
You need new LCD controller (there are more than one version, you need to match with the LCD panel): http://www.shopjimmy.com/catalogsearch/result/index/?q=ltv-32w3hd&stock=all

Westinghouse tv has only half of picture on screen

screen driver has failed on the screen, also known as the t-con board this controls the lcd screen, looks to me as its failed and just needs replacing depending on your location price is from £5 upwards in UK just make sure you replace the board with the same board as the original. t-con board is located on the back of the screen under the metal shield with the wires coming out going to the main av board 4 screws and 2- 4 clips on the board connecting the ribbons to the screen itself.
