Where is the inverter on a 39" Westinghouse LCD TV located? I have removed the back cover but not sure which component is the inverter.

This is model DW39F1Y1. I see the mainboard but not much else after removing back panel.

It is the little long board mounted on the side of the monitor. you can identify it by tracing the thick pink and white wires from the LCD panel to a little board that looks like it has some tiny coils on it.. you will see some little wires on one side and those pink and white wires on the other. It amplifies the voltage to drive the fluorescent lamps. Usually the lamps are what go bad instead of the board though,, go the other direction and look at the lamp tubes to see if they are black on the end.

Are you talking about the back-light inverter? If so, some models of LCD TVS; the back-light inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel.

SOURCE: removing base from tv

I researched this problem on the net and found the solution. Someone on one of the posts said the base can be removed by taking out four screws - all from the back of the TV. One screw is the one closest to the power plug, the next screw is beside it, the remaining two screws are the corresponding screws on the opposite side of the base panel (still on the back of the TV). Once these screws are removed the base comes off including the mounting bolt and the rectangular shaped plastic panel. There are no electronics or any components inside the base panel, only the bolt and plastic base which are held on by the four aforementioned screws. It was very easy to remove!

SOURCE: No picture on a Westinghouse lcd tv model ltv-20v4

I had this problem with these tv`s. The problem actually lies with the power supply inside the unit. Some of the units i`ve seen have 2 blown capacitors on the power supply (C7 and C6) replacing these works. On others, the capacitors as well as a few transistors (Q8 - Q1) are blown. But on all the sets i have seen with this problem, changing the above components restores full functionality to the system.

SOURCE: I need help with disassembly of Vizio GV42L LCD TV

remove all the screws and start at the bottom and push in the tabs, and work around the edges, being careful not to pry too hard, the cover has clips all around the tv. after the bottom is free and one of the corners the cover will kind of pop off if you use the palm of your hand and lightly tap as you apply sum upward pressure.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

If it takes my LCD Westinghouse TV 20 min. to warm up then the picture is fine, do I need to replace the backlight inverter?


Did you fix the tv Patty? I have the same tv and when i turn it on, it screeches really bad, but after about 20 minutes or so, all is well. I don't think its a main board issue, but i already ordered and replaced the backlight inverter - that didn't solve the problem. I read somewhere that the power supply is what the problem is, but i just don't want to start buying all of these components as my trial and error. I bought a new tv to replace this one but it is no where near my Westinghouse. I love this tv more than my 55" LED Samsung in the family room!

My Westinghouse TV has sound but no picture.


Hello Vernacamp, if you are technical you can open the unit, you will most likely need to replace one of the transformers or a capacitor on the power/inverter board. If you are not that technical you can open the back cover and you will need to replace the whole board, if you provide me the TW# located on the back of the TV I can give you the part # you will need to replace along with some websites where you can find the part. Please rate my answer if it was helpful.

Hello, it looks like your inverter boards are going out. If you are atleast a bit technical you can open the units back cover, and get the part numbers for the inverter board, these are the (one or two (master or slave) boards) you can get the part numbers and check out different prices at www.shopjimmy.com, or email Westinghouse parts department for price and availability at parts@wde.com.
