TV Philips Magnavox HD1918 C125 19" 1998 problem

Hello friends! I have a TV Philips Magnavox HD1918 C125 19" 1998. The problems is: When I turn it on, the screen goes white, then changes to gray with various scrolling horizontal white lines and one top to botton vertical white line, near the left side. The sound is working fine and I can change the channels. I have changed the TDA3653B CI, but nothing different happened. Does anyone have any idea for repairing my TV? Thanks in advance!

Sounds like you have some capacitors that are needing to be changed in the vertical circuit. The cost I cannot quote but, it probably won;t be worth the cost as replacement TV's are much cheaper now. Zeniths and other brands for the longest time have used not controls inside the TV, they are technician adjustments through a service menu only.

could be vertical output IC or capacitors located close around the IC

SOURCE: No picture, Horizontal line center of screen

Can be a case of vertical collapse. If this is the case, then the vertical oscillator and/or the vertical driver circuit are faulty. .

You can take you problem directly to zenith. They have a customer service post available here

SOURCE: White lines across screen and color faded.

Those lines are called vertical retrace lines. They appear when the G2 (screen) voltage is set too high, or when the video amplifier fails or lacks the high voltage supply (200v).

Have you got any electronics experience? You will need a multimeter and soldering skills.

If you do or know someone who does, take the set apart, look at the video amplifier IC (it is on the board at the back of the tube), get its model and download the datasheet. Find the pin that is labeled "high voltage supply" and with the set turned on measure it against the one that says "ground". You should have somewhere between 180-210v there. If that voltage reads zero or a very low value, the amplifier circuit is shorted or the power supply is not working properly. Unsolder the video amplifier and measure again, if the voltage comes up then buy a new amplifier IC, if it doesn't it's time to check the power supply. I believe you can find a service manual easily, follow the directions there.

Safety precautions: Do not under any circumstances touch the leads of any capacitors, and stay away from the big fat wire going to the top of the tube. Do not do anything inside the TV while it is plugged in (except measurements), and always use well-insulated tools. The high voltage section of the TV does not pose any health danger, however the shock it can give you will make you jump back, possibly into something sharp.

Philips Magnavox 13MT143S

I believe from your description that the vertical circuit has failed. either the IC or a capacitor. Sorry, but being only a 13" set I don`t recommend you repair it. unless you have a friend that would do it for you for the cost of the parts only.
