Re: Help with Philips LCD with no picture or sound

How do I go about removing the black chips from the inverter board? Once removed, how do I replace them? Do I need special tools?

Re: Help with Philips LCD with no picture or sound

Thank you, PlainBill. You have been a great help. I have found the repair kits you mentioned. Where can I get the parts for the modification?

Re: Help with Philips LCD with no picture or sound

The part # IS an LG/Philips. It's LC420WU5. As far as repair it goes, do I need to replace the chip or the entire board? Regardless, where would one obtain either one of these? Is this going to be the reason for having no audio as well?

Re: Help with Philips LCD with no picture or sound

Sorry about that. I typed the model number in the search box and it had 0 results. However, searching through the same issues with other model #'s I think I have found the problem. The largest of the black chips on the master inverter board has a small hole in it.

I have a Philips 42pfl7432d-37 LCD tv that has recently lost picture and sound. The picture went first. Then, a few days later, suddenly I had no sound. There were no problems leading up to this. The unit will power up. The power light on the front is lit and I will hear a momentary clicking noise inside the unit. I plugged my other tv into the devices to see if one of them was the problem. It was not. It would be great if I could get some troubleshooting help. I have little experience with electronics other than building a computer.
