The TV is on protect mode because an internal fault had been detected.

The first thing to do is leaving the unit unplugged from main for about one hour, this will drain power completely and can fix minor problems.

The standby light changing color is not a fault code, but it may suggest that the fault concerns the LCD CONTROLLER that is the main control board inside the TV.
Before replacing the mainboard the POWER SUPPLY
must be tested reading Voltage out on all outputs.
I think that the inverter on this unit is integrated in the PSU, the inverter section must also be tested.
All points where you may get a contact or a short must be tested.
Also solder joint and components on all board must be tested.
A shorted button switch on a faulty KEY CONTROLLER BOARD can cause protect mode.
The test and repair must be done by a an expert repairer.

Parts can be ordered online here: LVM-37W1.

Here are the possible cause(s) of the problem, it could even be the panel itself. this is the screen you look at. if so it cannot be fixed. it also could be the power supply or a buffer module. a cost of repair on these is around $650. you really should have a repairman look at it to be sure. Or I would suggest you to contact the manufacturer if the flat paner TV is still under the warranty period.

Hope this helps and have a great day!

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

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.
