Wish I could help, Dan- by the way, you're posting your problem under "Email Services"; I'd switch catagories.

Hi duarte
I`m going to help you with you tv but first;
Most of the time the power supply is the problem in your set but there are other boards that can cause a Vscan shutdown in the power supply.
There is a large board on the left hand side(from the back) that is called the Ysustain and there is a connector on it with the VS and VA voltages indicated and it comes directly from the power supply.
And on the right hand side there is the Xsustain with the same connectors.
I`d like you to pull them out one a time and try to start the set in between.
See if that makes a difference.

Good day!!!if you have power problem without blinking lights or standby lights (red) the possible problem is power supply board..However if the TV have blinking or standby light but won't turn ON..there are multiple cause of that and need further troubleshooting..

Sorry, unless you know tv's nothing you can do and the fix is very expensive. Basically not worth itHope you have warranty and take it backIt is fairly common to have few "dead" pixels that are not obvious I know this is not the answer you are looking for but all new electronics are made in such a way that it is usually not worth the troubleAfter all this is why they try to sell you extended warranty and if you pass you are stuck and have to buy new

Hello,

I need a base or stand for this model. Called Philips and they are no longer making the part. Any suggestions.

Check your inputs. If no signal then contact the people who sold it to you. They may send you to the manufacturer for a repair/replacement.

Are you saying the tv does not come on when you press the power button as it should? If that is the case - the philips tvs have a known issue with power supplies and if you have experience with electronics I'd say open it up and check the power supply for bad capacitors (bulged/leaking or busted caps) if you have component level experience replace them then try your tv again - ive fixed many philips tvs with this problem.

thanks,
michael

Hi, i see all the time these people who think that every fault in a unit, is a capacitor, when it simply is not.
While caps do indeed go "Bad" just replacing them seldom will permanently fix anything. What most miss is that also there is "Other" damage done to "other' even seemingly disconnected componentry.
As said usually we have a fault, the cause, the damage done, and the co-lateral damage ALL must be found and repaired, or the fault will simply reappear, in one form or another.
Accordingly whenever we embark upon a repair the very first place we MUST start, as I tell all my students, is with the Power Supply.
Here we must check ALL voltages, as if they aren't correct here then NOTHING can nor will work correctly anyway.
So to check said supply one simply MUST HAVE a service manual.

these tv have a comon short problem w the video &audi bord shield if you remove the cap only it usally fixes this

You will more than likely need your capacitors replaced. That is the most common problem with these.

Step1: Reset power to the TV or DVD or Cable box

go onto step 2 if problem is there

Step2: check all connections
making sure they are all pushed in all the way

go onto step 3 if problem is still there

Step3: Remove one connection at a time and make sure they are going into the right plug

if problem is still there give me more info.
