Question about Philips 42PF7421D 32 in. LCD HDTV
I'm lloking for the mounting screw size for the screws that go directly into the back of the TV. For some reason these were not included when I purchased the TV.
I don't know the model in particular, but most of these sets can be wall mounted if you have the screw holes for the mounting plate in the back of the set.
What I believe the tech was telling you would be that it is best to not wall mount the set. The reason is that we found that we have been seeing a higher failure rate from sets being wall mounted. This is because the surface of the wall reflects some heat back in the set, and thus causes it to internaly run warmer. This is also the same from running a set inside of a cabinet. The complete surface area behind the set being very close to the wall surface blocks cooler air circulation. It is best to run these sets on a stand that is out in the opened at least 1 foot away from any wall surface.

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. I don't have the Service Manual on hand for your model number to tell you what the code means.
Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

First of all a standard screw will not work. You will have to visit your local hardware store and purchase a machine screw to fix the problem. In many cases you will have to use an estimated guess and gamble your time and money. The length and width of the machine screw will be found at this store. The effort is miniscule and money will be meager. Remember, do not use a standard screw!
