It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner o), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact service tech and let them recommend an authorized service center in your area. Sorry, but this is a rather serious problem.

Screen is blackened on top of screen


assuming your TV is an LCD, there is an issue with the CCFL lighting tube/s and one or more needs replacing/repairing.
if your TV is LCDLED then there is an issue with your LED lightstrip - probably faulty circuitry and would need replacing.
unless you are confident with stripping your TV (which i doubt) then you will need to pay someone, and it will probably cost LESS to just buy a new TV -- they are getting very cheap.

Get sound and "invalid format" message displayed instead of picture


Could have still been hit by a surge. Take the back off of the TV and look at the main board were you connect your HDMI. See if it is scorched or components that blackened. Also check your DVD player on another set. Your DVD player could be the problem.

As I was watching tv, today, I heard a "pop" and the picture blackened on the tv. I have a mitsubisi 65 inch dlp. There is no picture, only sound.


There might be a shorted capacitor in the video amplifier section. You can locate it through the physical appearance of the capacitor it is blown up. Replace it with same value but you have to get first the voltage output across the capacitor it must be within the voltage capacity of the capacitor. If the voltage output is higher, there is problem with the voltage regulator in the power supply section.

Philips TV Power problem


I can't be the fuse like you say it is not blackened or open. Set may have a loose solder joint in the power supply look around large IC's and resistors (anything that genrates heat) can cause this problem. A faulty high voltage trasformer can do this I will check and see if I have any info on this particular chassis.. Oh yeah the deguassing coill is not doing it.

Picture getting darker


The tv has a room light sensor,
shine a bright light at it , does picture get brighter?
other wise when it is cool open the bulb door , is it coated or blackened, Don't touch bulb at all.

and a heavy covering of dust on internal mirrors will cause the same effect.
you will need help to clean it.

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
