  1. Hi. I have a Westinghouse SK-32H590D LCD TV. I was wondering how to fine out what the PSU output voltages are suppose to be.Thanks,Bill

  2. Hi Bill! Search our site using your part number. It should be 4900253180, or a number similar to that. Take a look at the second image on the listing to see details of the bottom side of the board.

    Check out the pin outs for the main board connector screen printed on the board. The other connector is split into 2 parts. Gnd and 24V's for the inverter i believe. If this doesn't help you, give us a call and ask for Rich in the Repair Dept for tech support!

  3. I have a Westinghouse 32 inch tv f/s there is only a little blue light nothing else no sound no screen nothing just a small humming noise from the upper left hand corner where the capacitors are mounted ???? !TV! like I said does not turn on ?? even pushing the on/off button nothing?

  4. It's a SK-32H240S. The board mounted to the left connects the same way 6 little screws and unplugs the same way same amount of plug ins 6 on the left 1 on top 1 at the bottom ?

  5. @haileyzworld1 – I would suspect there is a problem with the back light inverter. There are a number of possible board configurations used in this model. Go to the Shop Jimmy website and search SK-32H240S. Match the inverter or power/inverter board used in the set to be able to order the correct board.

  7. @Glen Fawcett – It could also be the Power Supply that is causing this. It can be tough to determine without having more details. Thanks and please let us know if you need any other help! (877) 881-6492

  9. Hi, I have a westinghouse ew73s5kw, a couple of weeks ago the directv tech came to hook upa new room genie, after he did the video went out on the set. No matter which input I use there is a stripe of green lines that run vertically across the t.v. audio still works on the set. target/westinghouse are being pain in the butts about fixing the set even though it should be under warranty. Anyway, I watched the lips board replacement video, is the problem or could it be something else?

  10. @Rory Carroll – This problem would most likely be caused by the t-con board or a bad panel. The panel can be very difficult and expensive to replace, typically we recommend replacing the TV if you have to replace the panel. You could try replacing the t-con board on the TV, as that may fix the problem. The part number for your t-con is Westinghouse HV365WXC200. I will send you a youtube message with further instructions on how to purchase your replacement t-con. Thanks!

  11. Have a 32" SK-32H240S.  Just replaced the power supply board and when the main board connector is plugged in I get the hum from the center transformer on the board, when unplugging the main board the hum goes away.  This is the same issue I had prior to changing the power supply.  Still have no voltage on the main board connector going to the main board with it unplugged.  Any thoughts?

  12. I have a 42'' westinghouse model num is tx-42f430s.
    It powers up with backlight and sound. No Video,no menu access.

    Bad inverter boards?????    

  13. I have a Westinghouse VR4025 and the power stopped coming on after power outage. The light under the TV stays on, but the TV doesn't actually turn on; no video, no sound, even though electricity is still reaching the light under the TV. I've replaced the power supply, and nothing has changed. If the problem is the inverter, wouldn't there be more happening?

  14. I have a westinghouse tv sk-32h510s that doesn't power on at all! No clicks no sound seems completely powerless. What board to change? Main or pwr/inverter. Since was given I don't want to put a lot of money in it. Worth a try for one board

  15. I have a Westinghouse 32h240s which is behaving strangely. When I hit the power button, the screen lights up for about 3 seconds, then goes dark again. Once it goes black, pressing none of the buttons makes it light up again. When I press the source button, then power off and back on, it shows the source changes before going black again. Could this be the ribbon cables shorting out to the backlight?  

  16. I have a LTV-32W3 HD, how do you remove the plastic cover that goes over the inverter board? Dumb question, but I don't want to just rip it off.

  17. I have a westinghouse model #tx-42f970z will not turn on, I changed the power supply board but it still will not turn on can you please help me

  18. I have a element flat screen model # elcfw328 sn # 12200227540056547 I've replaced the power supply / backlight board and I still have only sound can see menu with flashlight

  19. Hey I hope someone can help me.
    I have a 55 inch 4K Westinghouse WD55UX4530…The TV powers on and even displays the Westinghouse brand when turning on. After that, there is no display on the TV but sound. I can see moving images in the back. I took off the back panel everything looks good but I'm pretty sure something is wrong. Would I need an invertor board or would I need to replace my backlights.

    I really appreciate any thoughts on this
