    Re: 42PFL3704D/F7 No picture

    Since no one chimed in to help me out i ordered a new T-Con. Replaced it and now the TV makes a high pitched buzzing noise as soon as i plug in the power cord.

                        Pretty sure they wouldn't tell you to get lost. They are not some fly by night company. They are one of the larger parts distributors for a reason. They offer 6 month warranties on their boards and stand behind their product. Everybody has a bad board slip through the cracks every now and then, its part of the business. Just give them a call and they should take care of the problem.

                            Remember most of these boards are removed from TVs which have been dropped or physically abused and the LCD panel broken. There's no real way to tell if the boards are okay. 98% of the time they are but once in a while you'll get a TV with a broken LCD which also had an issue out of the factory, or one which developed over time and then was damaged. And it's not really economical to test them, given there are hundreds of T-con boards and so few matching combinations of panel and main board.

                                    Swapped TCon with replacement and i get the same issue. This thing is a PITA. I'm about ready to throw it in the dumpster.

                                            Put it on craigslist for best offer and see what you get for it. Its got to be a bad panel now but you dont have to list it that way on craigslist.

                                                I didn't notice that there was also a different brightness bar in the darker area.

                                                Although the panel could be bad, some T-cons and main boards can be calibrated to deal with different levels. Try entering the service mode.

                                                Some people will buy a TV even with that problem as it's fine for gaming/OTA TV, just doesn't look as good but I once lived with a CRT which had a large horizontal grey bar appear on the screen next to anything bright (probably a bad HV supply), didn't matter that much.

                                                    I agree. It would be a waste to throw it in the trash. Me personally, I'd get more money by selling the Tconn board, inverter board, and power supply on ebay since I know these work. I wonder if it does this under different inputs or different resolutions on a computer?

                                                                    It does this on all inputs and resolutions when connected via HDMI to computer.
                                                                    Usually with Philips you have to enter a series of numbers on the remote. Those $@%#@!%%#@!! did something I never saw before on this chassis. You have to cut a hole in the front of the remote to expose a button. Pressing that button will send the TV into service mode.

                                                                    PlainBill

                                                                                    The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                                                                                    Original T-con:

With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                                                                                    First replacement T-con:

                                                                                    Problem

When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                                                                                    I ordered a supposedly ‘new' Tcon board this time, and                                                                                    ...
