Question about Philips 50PF7320A 50 in. Plasma HDTV

Open Question

Hi. I have a Philips Plasma TV model no. 50pf7320, and I have not been able to track down the problem which goes as this: after replacing four 58" z. diodes on the Y "Sose" board, together with 2 fuses, the screen started displaying thin vertical lines 5 inches from the bottom. What could be the source of the problem?

1 long and 4 short blinks for this model is specific to class d audio amplifier on small signal board. if it is intermittent where this sometimes happens and you can unplug and replug and power back on would be related to the firmware version but if version is correct you would still need to replace ssb

See if you can use the remote to shift the picture to the right. It depend on how far the line is to the right. If that don't fix the problem the set will need to have internal boards replaced. It may be the logic board and the logic buffers...

When you bring up the onscreen menu, are the lines running over it or behind it? If they are behind the OSD, play a DVD and see if the lines are present there. If not, I assume you are only seeing the lines while watching cable/satellite? You might want to check the connection and try different cables or inputs to determine the issue.

If the lines are present over-top of the OSD, this is an issue within the TV so try a power drain:


1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use.
2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board. 3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on.
If the lines are still present, service is likely required. I hope the above works for you.

You have a bad lower Y-DRV (or buffer, which ever you like to call it). If you want, you can change the IC itself... but they are usually smothered in hot glue. This board attaches to the Y-SUS that you were working on. It is common for the Buffers to knock out the Sustain board. I hope this was helpful, best wishes.

My phillips tv 50 plasma hd can't show picture


Hello,


Problem is in either power supply or - my bet - the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

hope that help out......

Blinking red light . Tv won't turn on


I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired ofcourse) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices. Here are some options for you. 1. Have it fixed by a professional 2. Open your TV and find PSB. Checkfor faulty caps. If you find some (bulgedor leaking) bad caps replace the entire board. 3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds. I have a tip/tutorialon this site that may also help. Itgives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It'scalled: Fixing the Philips Turns/shuts off on its own problem. Hope this helps and Good luck.Kaufman605

Four red flashes


if 4 blinks is consistent and even after unplugging tv still does not power on would recommend replacing small signal board as error is i2c communication failure which is specific to microprocessor located on small signal board
