Tv wont turn on at all

You have a bad small signal module! Location should be in the rear left side. The board will require extensive work to pull out and reworked or replaced! This board will have three large heatsinks with convergence ICs and an audio ICs attached to them.Good Luck and thanks for asking!

TV still has life left!
Video board may need checking

If this set is more than ten years old then I would recommend it's replacement. If it's not then a house call is your only choice due to the size and weight of your television. I can't find any data with Phillips about this set which usually means they no longer support it's repair. (They are only required to support it for 5 years after it's out of warranty.) The hard part is finding a repair technician that is competent to trouble shoot and repair this brand. Don't forget that all the components in your set are just as old. Failures happen all of a sudden with usually no symptom. The fact that you can turn it on with no result means an internal failure.

The tv setting may be on AUTO. This can be changed at any time to wide screen, panorama, etc. I prefer panorama

Check fuse #1003 on SSB and Audio Ouput IC #7700.

Will you have got a lot of years on this unit. There could be a lot of things wrong here are some things to check.

Good Morning Chris,
OK, first of all lets unplug the TV and wait 15 minutes for the High Voltage to discharge.
Remove the back and follow the power cord to the power supply. Somewhere around there you should find a fuse. (there may be more than one) get a bright light to look inside and try to find as many fuses as you can. Remove each fuse one at a time and check them with an ohm meter.
If you don't get a good solid reading on any of them replace the fuse or fuses with the exact same rating. Even if you get a reading and the display is jumping around and will not stablize, replace the fuse. Usually a good fuse taken out of the circuit will display a good steady reading on the meter.
I hope this solves your problem.
Have a great day!

it can be turned on and off in the menu. under parental control. you may need a code to turn this on or off.

These off brand almost always have power supply issues that have to be troublshot. $150 at a local tv repair.

Un plug the set first then remove the back, and depending on the model number you should have two or three fuses on the board on the right side where the power goes check them for continuity with an ohms meter. What is the model number of your set? Also does the led indicator light up?
