Ahh that is a simple repair, is either a cap or the vertical out put, a resonable tech would charge you less that $100.00, but the thing is that you can get a better tv with digital tuner for like $180.00 so is your choice.

good luck

I have a 27 inch panasonic and have about 19 real thin lines across the top of the screen. It is in the top 4 inches of the picture tube.Model CT-2701G Built 9/03


Scan coils (field) measure about 5 to 15 Ohms from the plug where they connect to the main PCB
Look for the cables that come down from the scan coils (deflection yoke) to the main pcb
its either two cables and two plugs or a 4way cable with one plug to the main pcb
2 of the wires goto the vertical(height) and 2 to the width
try to work it out which (the fattest wire is width)
The width ones go towards the loptx(line output/flyback transformer),
and the height ones go to the field output chip (or transistor pair) Follow the printed circuit from the plug and look for a 7 or 9 pin chip on a cooling plate(heat sink for the posh),
it should have a diode connected to it and about 25v on both ends of the diode.

I have a magnavox tv model # 27MY6005D/37. Where can I get an owners manual and I have a line two inches on top like the tv bottom is on the top. How can I adjust that? Thank you


According to the model# you have a 27 inch TV so this would mean you have a bad capacitor in the vertical circuit 100uf 35v and you may need to replace vertical IC as well.Call Mats for parts 1-800-628-1118 for owners manual try Encompass Parts 1-800-638-3328.Somtimes if picture pops back to normal then resolder Vertical IC but if thats not happening, replace parts.

Convergence point problem on a Philips TV


The 55pp9352 model number uses 2 of the STK-392-120 convergence chips--if it will not adjust in some direction--both chips and any of the 6.8 ohm resistors around them that are bad need to be replaced.

The reason this happens is the chips are about 2 1/2 inches wide X 1 1/2 inches tall with a metal back--they are attached to separate metal heat sinks and a white grease is applied to each to transfer heat quickly---after several years the heat sink grease dries out and one of the chips cannot stay cool enough and fails.

Pretty common problem in ALL rear projection sets--if model is 55pp, it is 55 inch set.

You can buy the chips on Ebay for less than 12 dollars---the resistors if needed are cheap parts.

It depends if you are able to do the repair yourself or need to have someone do it for you--most shops get at least 300 for this kind of repair--considering the parts cost less than 20 dollars if you can do it yourself you can save a lot of money.

Any good tech can do this repair in your home in about 1 hour--I know as I have done hundreds of them.

If you need help or advice let me know--I am here to help people.

Hi i have a jvc 27 inch tv, an older model probably a 2002 model.last night as we were watching the onscreen set up menu came on and kept going thru the whole set up over and over and nothing would stop...


The microswitchs are probably leaky. Ask your local TV shop what they would charge to change the switchs in the front. On a 27 JVC with a good picture I would charge $85.+ Tax. You have to decide what it's worth for you. I would say it's worth $85.+Tax for me. I that helps let me know.

This fault happens with just about any tube type projection set. The convergence IC's simply need to be replaced. They are two black, 2"X3", stand up ICs that will start with the letters STK on the surface of them and are mounted up against a large metal heatsink. If you have the soldering skills this should not be so hard for you to do, but please if you do not have the skills or experience to replace these IC's call in a pro to assist you with this repair. Good Luck
