If the power chip is okay check the drivers. Make sure it's getting an input. Audio is picked off of the IF section. Make sure you have audio there and trace it out to the power output.

Tip

42PFL7422D/37 Flat Panel LCD TV no picture no sound


I HAVE A 42 INCH PHILIPS MODEL 42PFL7422D/37 TV.

MY PROBLEM IS THAT IT HAS NO PICTURE AND NO SOUND.
THERE IS A GLOWING BACKLIGHTING.

THERE IS A BLUE LIGHT WHEN I TURN POWER ON THE TV. NO CLICKING RELAY SOUND.

MY PROBLEM WAS IN THE SLAVE INVERTER BOARD.

THE IC CHIP WAS BLOWN - SEE PICTURE. THERE IS A BURNED, DARK BROWN MARK ON ONE OF THE CONTACT LEADS ON THE CHIP.

THERE ARE $20 FIX IT KITS THAT YOU CAN BUY ON EBAY TO REPLACE THIS TINY LITTLE CHIP BUT IT'S RECOMMENDED THAT YOU SOLDER VERY CAREFULLY. I TRIED, AND DAMAGED THE BOARD SO I BOUGHT A USED ONE.

REMOVING THE IC CHIP IS PROBABLY BEST DONE WITH A HOT AIR SOLDER GUN. THEY COST ABOUT 50-200 DOLLARS.

AFTER INSTALLATION IT FIRED RIGHT UP.

IN ADDITION TO THE JUST BUYING ANOTHER INVERTER BOARD, I ALSO TESTED THE MASTER INVERTER TRANSFORMERS. ON THE POWER SUPPLY BOARD, I TESTED THE DIODES, AND RESISTORS, AND CHECKED THE FUSE.

AFTER ALL OF THE ABOVE, I UPDATED THE FIRMWARE BY GOING TO THE PHILIPS WEBSITE.

LUCKY FOR MY SITUATION IT WAS NOT THE MASTER INVERTER, MAIN , TCON, POWERSUPPLY, OR DAMAGED BONDING ON THE LCD PANEL ITSELF.

TOTAL COST $50.

GOOD LUCK!!!

Phillips 52'' projection tv.Picture goes small then large then off


Your original problem was/is an "opto" IC (chip),which causes the power supply to regulate low when it fails. It is a 6 or 8 pin chip. Sounds as if maybe more has failed now. Switch mode power supplies are not for the faint of heart,or DIY. I recommend having it troubleshot by a tech.

The red light on the front flashes and tv wont turn on


1) Convergence chips are shorted....One quick test is to desolder and remove both STK392 chips....then power the set on. If the tubes light up the chips were shorted. You can get new ones from www.TvRepairKits.com

2) Another possible problem is a bad HVG - AKA the flyback.

Try the convergence chip test first. Note: On some Philips sets you can just unplug cable "1516" instead of removing the chips.

For instructions on how to find/remove cable 1516 visit the website listed above and click on their tips page. On that page click on the "Magnavox DPTV3xxx Checks" link.
