This TV set is still under the warranty and it seems proton has no local service available to you. I know its to late to tell you this but anytime you purchase a set, ask first and see if there is a service local to you. Ok enough of that noise.. I would go back to the store where it was purchaced and ask them if they know of any local shops that handle the warranty repairs.. If you want to pay for the repair, and that will most likly be alot for a flat panel set, You will have to call back proton and ask about the shipping cost and whos responsible for that.

SOURCE: Black Screen after 5 mins. of use

It sounds like the entire screen goes blank with your problem. My problem is the lower half of the screen goes blank. Do you think the SSB is also the problem? What are your thoughts about the "Video Board" or the X Board?

Do you know where to purchase parts?

Hi, All.
I ordered a new power supply module on ebay. Cost about 106.00 delivered. Came in a few days. I replaced the unit, bunch of screws, all wires were cable plugins, no problems at all.
After reassembly, it worked. What can I say? Sometimes ya just get lucky.

SOURCE: No picture on Philips LCD TV

One very common problem encountered on many Philips models, old and new, In some cases, the SSB board has to be replaced as the resistor on the PCB on the back of the CRT had to be fixed. In other cases the Y Sustain board had to be replaced. If the problem is not due to these two issues, then the capacitors will need to be replaced as they only have a fixed guaranteed life. Thus, it would be wise to take out an extended warranty on Philips due to this common repair issue which often occurs after the limited warranty has ended. Or you could just call your local repairman. There are lots of websites on how to fix it yourself on google. There could be many reasons. Hope this helps!

My Phillips flat screen model 42fd9935/17 has started going black after playing for about 2 hours... you can still hear the sound, but the screen is black... the picture will come back after turning the tv...


The cost of getting this plasma fixed is not costwise compared to getting a new TV. I recommend NOT to get another plasma but get either an LCD or LED for the best quality compared with price. Plasma parts can be quite expensive especially for a 10 year old model or may not be available.

Philips 42PFL7422D/37 42-Inch 1080p LCD HDTV Picture went out but still have sound. Any tips on how to fix it?


If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.

My 42 lcd phillips tv colur turns red and zig zag lines then turns itself off why is it doing this


You are not the only one I can tell you that. I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Screen is black but we have sound


The problem is a faulty inverter kit (2 boards).
I live in the Netherlands and had it twice, tv is 2 and a half years old! In the Netherlands Philips replaces the inverterkit without any
costs for the consumer (even after warranty time) cause they have
admitted that it is a production fault.Philips made a new inverterkit
which should solve the problem indefenit.Be sure the kit is Version
1.3! I had 1.2 after the first problem, and that went wrong after 7 months again. Today got revision1.3 installed which is Philips final solution.

Did u have audio before ? If so you might have a blow audio amp. If not it might just be a unplugged cable. This model of tv is bad about bad audio problems mainly a blown speaker and blown audio amp.
