You all know you picked the Westinghouse brand cuz it was cheap.
Avoid cheap brands like Vizio, Magnavox, Philips, and Sylvania etc... If you don't buy eventually they will go away.Next time get a plan fro the TV. If you had a service plan on the TV you would already have a new one. Plans always cost less than repair and shipping. Don't be cheap. BUY THE SERVICE PLAN.

The simplest problem would be the failure of the backlight.

In case you don't already know it, there is one, and they may or may not last forever.
Also, there is an extra power supply to produce the high voltage the lamp needs to fire that may have failed.

Sometimes, you can look at the screen from an angle to see if there is any sign of movement.
If you can see program material causing a change in the faint image, then you can be pretty sure it is one of the two problems mentioned.

This problem is with fair certainty the power supply.
Modern power supplies are designed to shut down if the current drawn exceeds the design level which indicates that something the supply services or the supply itself has died.

If you are adventurous, you might pull the plug on the set, allow the set to sit overnight, gain access to the innards, and with good light, inspect any boards inside. If you see one that has few ICs but many more larger discrete parts, this will be the power supply.
You are looking for components called electrolytic capacitors that are almost always cylindrical and mostly installed upright at 90 degrees to the board with leads passing through to the solder side.
This same type of component in smaller dimensions is still used in a horizontal package with leads bent down and passing though holes to the solder side.
The latter are becoming more rare since they don't lend themselves well to robot assembly.
Many (not all) will show signs of pregnancy when they fail, bulging unnaturally when compared with others. Now and then, there may be traces of a crystalline deposit around the end where the seal failed from internal pressure.      
 
These will have values listed on them in uFd & VDC and sometimes, a plus/minus number lying about the precision.
Some also have a date code (rarer) that will look like four digits:
 
2403 = 24th week of 2003
 
Most electronics suppliers have a stock of the various values but if they have a date code at all, try to get only those made before 2002 or after 2006.

 
The larger caps will probably be OK since the failure is likely related to functions other than brute-force filtering. A pretty good 'rule of thumb' is to replace any caps you see bulging that are 100 uFd or less.
 
If you choose to replace these yourself, you will need a quality soldering iron with a small, preferably iron-plated tip, rosin core solder and a sponge which when wetted is used to frequently wipe oxidized solder from the tip this should be kept bright and clean and fresh tinning will keep it that way.
 
You should also buy some solder 'wick' with the iron; this is used to place on the solder you wish to remove and then heated with the iron. Properly used. the wick will absorb nearly all of the solder from the lands from which you wish to remove a component.

I have had this problem since about superbowl time. If I powered the set off, waited 15-20 seconds, and then powered on, it would work again for a while. Repeating this drill a number of times would lead to stable operation. We resorted to a course of turning on some XM music from DirecTV when we weren't watching. I tried a technician knowledgeable on this set, and it would have cost $500-800 to repair the set. We learned from different forums that the likely culprit was either the power supply board or the LCD controller. We also picked up the rumor that Westinghouse had quit making replacement part. It would seem that the management of this organization has a death wish. TO THE CHASE: shopjimmy.com is now selling parts from canibalized sets. They have a non-DOA warranty and a good return policy. A power supply from "Jimmy" solved my problem. I have one important hint: To remove the back, take out the obvious screws and the base. Then remove the ~5/8" rods that protrude from the bottom. There is a screw up inside each rod.

LVM-37w1 after 5 minutes of viewing, picture and sound go off. Blue power light turns orange. attempts to turn on TV are unsuccessful. Blue light immediately turns orange.


I saw this fix posted on another blog by a fellow named Patrick. I tried it today and it it worked. It fixed my Westinghouse lvm-37w1. Basically disassemble the back of the TV (removing all the screws on the edges and middle). Remove screws holding bottom speaker and stand. There are 2 chrome rods extending down. There are small screws inside holding them on. You can turn the rods and unscrew the screws but need a small screw driver to put them back on. Remove the black cover on the back. remove the plates on the lower middle section. You will expose a printed circuit card. unplug wires and unscrew 4 screws holding it in. Remove it, turn it upside down and inspect the solder joints near the lower middle (especially under the gray relay on the other side). I found 4 solder joints that were cracked. Resolder the larger solder joints that are cracked or look bad (small solder joints are too delicate). Put it back to gether and it should work now. Mine works great. No more black screen with no sound.12_2_2011_5_11_21_am.jpg

I have no picture but I have audio


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.

No audio, picture okay


Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

It is worth fixing but you have to replace the power supply. It is a fairly common problem with the Westinghouse units.

WON'T POWER UP


I had the LCD repaired. It turns out that the power supply went out. It cost me a few hundred bucks but it was worth the repair rather than buying a new one for 3x as much.
