    After I explained to my daughter I no longer have the tools to do this kind of work-- she decided to have a technician fix it for them.

    Thanks for your suggestions, and I will keep you in the loop until it is fixed.

Thanks for using FixYa. To start with open the back of the unit and then check the power supply board for any bad (bulged/swollen) capacitors. Power supply board is the board where all the power cords/plugs goes into. The inverter is the power supply source for the backlights. If that’s the issue then it’s always better to replace the inverter board completely just to avoid any future issues. After you have checked that also check the main board and if you can use a multimeter to test the components on these boards. All this should only be done if you have knowledge of internal circuitry of the unit as the components consists high voltages even when in off position. Please do accept the solution if the issue is resolved or post a comment for further assistance.

    Hi Rylee,

    I will not be able to check the power supply board and the inverter. Do have an estimate how much these parts will cost if I install them myself.

    Thanks for your reply. You'll need to check or get it checked that which part out of these two has gone bad, although it seems to be the power supply. The cost to get this repair from a professional will be around $250-$300 including labor depending on the parts that have gone bad. If you DIY then it'll be around $150-$250 depending on the parts that have gone bad. Please do accept the solution if the issue is resolved or post a comment for further assistance.

A lot of these fail:

low sound
no sound
intermittant sound
no remote functions
no channel up or down
etc etc

Last time I looked board was around 100 exchange rebuilt

I have an 51pp9100d/37 Phillips Tv, and i the red and green colors on the picture are skewed to a weird, almost sideways, S shape. I was wondering if this is an easy fix and cheap, i don't really know...

From what you have said it seems that you need to replace the Convergence ICs, they are Big Black ICs and will have Part number on them ,example STK392-110
Mats Electronics has Parts $9.95 each IC. 1-800-628-1118
PTS rebuilts boards 1-800-844-7871

I need the service mode sequence for my philips 51pp9100d/37 so I can manually change the resolution on my tv. The resolution somehow was changed and when I HDMI my laptop to the tv it wont display t

I suspect that you may be using a cable or sat box rather than that set's internal atsc tuner.
Sometimes these boxes are not set up properly or reset themselves to a lower resolution.
Go into your box's settings menu nd look for the resolution settings. Verify that all of the modes or at least the maximum resolution for your set is enabled.
