My Philips Plasma TV model 42PF7220A/37 went into "no menu exit" mode on 11/28/2007. I went to www.usasupport.philips.com and downloaded an upgrade. Just followed the instructions and my TV is all better.

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
By the sounds the light source is gone and will need to be replaced. This is not something that is customer serviceable.
I recommend contacting Philips' customer service. They may likely have repair techs in your area. I'd expect the cost to be between $150 - $300. Their customer service number is below.

The red light usually indicates a power section problem. It would be something just about gone or overheating.
You will have to take this into a repair shop or a Phillips repair depot. You really should get an estimate for this before commiting to getting it fixed. Depending on the year it may have a sperate power board (cheapish to fix) or might require the main board to be fixed (lots of $$$) Worse case is that it can cost as much to repair as just buying a new replacement tv. So get the repair estimate and check around for replacement costs and let that be your guide as to which way to go with this.
Hi, the power supply board has a little board towards the connectors. This board has an led and it will blink if there is an error, check how many blinks there are and then check on the on the power PCB next to this little board you will see the error explanation. Also check capacitors on the power board next to the control board connector, replace any bulging ones. I hope this helps.
