Philips 51PP9100D/37 Will Not Stay On

Our TV will turn off the picture by itself and show ''weak signal'' and after a few minutes will turn off by itself. Once ''weak signal'' is up, we are unable to use power button or remote to turn off.  We have to turn off/on power strip to turn TV back on. Then when it comes back on, sometimes there is no sound. It is a game of turning off and on to see when the sound comes back on. Sometimes it will be fine after that and sometimes it won't stay on for more than a few minutes. The TV is only about 4 years old and we build a niche around it so really want to fix this TV and not buy another. PLEASE PLEASE any suggestions?  Thank you in advance!!!

O.k. your internal digital tuner sounds like its goin. what you need to do is take the back cover off and trace where you hook up your
digital signal (cable,ant.hdmi).then you will see 2 silverish boxes one is analog,other digital. get refrence #s off of board of the tuner thats conneted (trace the signal input wire to be sure) then e-mail me ohmega1080@yahoo.com

PHILIPS 51pp9100d/37, picture is warped ? where do I get the parts i need to fix it ?


If it looks like attached photos it needs both of the convergence IC chips replaced. They should be stk=392=120 OR a few models used the -110 chip.

A lot of these fail:

low sound

intermittant sound
no remote functions
no channel up or down

Last time I looked board was around 100 exchange rebuilt

You have weak capacitors in the power supply and the signal board. I have not repaired this particular unit, but have experienced this with other Polaroid TVs. You will need a TV tech to replace those capacitors. It is a very time consuming task and requires patience and much care to remove the capacitors. Tell a tech that they must be very careful when they remove a cap in the signal board, as they can peel off a pcb trace. In most cases they replace the signal board, but the capacitors can be replaced! Thanks for asking and show a few hands of support!

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.
