SOURCE: Philips 42PF9956/37 Plasma TV - Looking for y sustain board

it isnt the Y-SUS board, it is the Power supply, iv fixed this exact problem twice in the last month, try turning the tv on, and when it turns green, unplug it real fast, while light is still green, after 15 seconds plug it back in, then hit the power button, if it dont come on, hit the power button again, this time, as soon as it turns off, hit the power button again to turn back on, sometimes you can trick the tv and it will turn on, at least i was able to do it, and once it comes on, it should work fine, untill you turn it off again.

what you have is a bad inverter transformer on the inverter board. I nashed my teeth on this problem for a long time because no diagram is avail. Here's the fix for you:

Remove the invertor board. Take an Ohm meter and measure the outer 4 legs of each transformer. Between pins 1 and 4 (side with the white dot near leg 1) you should read .3 ohms. This side is usually good. Between pins 5 and 8 you should read approx 1.8 to 1.9Kohms. ANYTHING above that is a defective transformer. I'm sorry I do not have the part number for this, I've just been using an old board from a set with a cracked panel. If I can find a part number I will try to post. You can try Encompass parts on the web, they may be able to supply part number and transformer with location number.

Oh yeah, you can most certainly change the power supply by yourself.

It's easy to locate - just follow the power cable - and easy to replace.

Only make sure to let it discharge before you operate it. 10-15 minutes disconnected from power should do.

However, there's no guarantee that the problem is in the power board.

There is a very good chance it is, in fact, not there.

There's another board which commonly fails on many plasma TVs and the effect is exactly as you describe. It's called Y-Sustain board and you can tell which one it is by looking at the side of your TV and seeing which large board has manny plastic connections that enter the display on the side.

That board often has one or two fuses on it - I'd check those first.

SOURCE: my philips lcd tv has sound but no picture what is

change the backlight (cold cathode light) on your monitor.. If you are able to open the back of your lcd monitor carefully, the backlights are located at the upper and the lower part of the edge .. replace it with conventional cold cathode lights(protective tube was removed)... there are also instances that backlight was good but the ballast transformer is burnt. Replace the ballast. Its very cheap to replace that.

Most likely A power supply problem, you can try unplugging the cord waiting 3 minutes and retrying, to see, if not the open the back and see if the caps are in good condition, even though it did this last year, could be more a problem now since last 1.5 years ago its was something else. If you don't know how to solder then time to call a repairman.

Sounds like you either have a defective LCD panel, LCD panel tab connection, or a LCD to T-con faulty connection. Does tapping or squeezing the left side of the TV change anything?

Philips 47PFL7642D problems


Meaning your screen is going black. Some of your capacitors are dead or exploded. There isin't many capacitor now that can hold enough energy to keep your tv alive. They work in serious and the few left are supporting too much voltage. Go to radio shack with an electrician friend and buy them. Only 5$ each. Must soder new ones. Make sure the support voltage of the capacitors are even or a bit higher. They are measured in micro ferrits. It will cost you less than 30$to fix tv perhaps. If you take it to fix they'll. Charge you At least 300$. Or buy the whole board on ebay for 70$ to 150$.
Good luck!

No signal


You need to find which is the right channel. It is usually AV2. However make sure you plugged in all the cables to right places. Also, call your cable company and ask them which channel might be, since this new HD tv are so different.

One more thing, If you have a VCR/DVD connected to the TV, you need to check the channel of the VCR/DVD
