I have a Philips 29PT3323/79R. It turns on and no dark picture & sound appears for a couple of seconds and then nothing? I am a tech, is there a common problem to check with this model TV?

Hi and welcome to FixYa,

Initially, have you checked the vertical IC and/or the Vcc supply to it?

Good luck and Thank you for using FixYa. Happy Holidays.

Yeah it´s a hard tv to Fix...but not impossible...

First You have to Check all the Board for Cold Solder and fix it...after this check the Power Supply, ´cause they are the champion of the Problems in Philips PT´s models..see if you can find any blow capacitors near the deflector Conector...Good Luck!

What make and model number remote do you have. Often the model number is located in the battery compartment.

Did you check for any blown fuse on your tv and also did you check the inverter ?

If you have checked fuse and inverter then check soldering points of SOPS-transformer (T5663) and line-transformer (T5620) and check IC 7220 (TDA 1521Q/N2; 4822 209 73311) and loudspeaker(s).
