Sir it is present in the control board of your TV sir.

both convergence IC and vertical ICs needs to be removed and soldered.
but since u wil be working at a very high voltage there is always a risk of electrical shock.

because the flyback voltage is enormously high.

No picture or sound


Often these errors are related to a bad solder joint on the main-pcb or crt-board or what was once just a solder connection failure to the vertical circuit is now a full cascade failure of the vertical output circuit. You can check this by tapping on some parts on these pc's with an isolated screwdriver. Whenever you tap, and the picture goes dark, you're sure it's a bad solder joint and you'll need to re-solder it. Also bad solder connections around the flyback transformer as well as in the vertical sweep circuits. Please If you have no TV repair experience, call in a tech to assist you in this repair. Good Luck and let us know how you made out with this repair.

My phillip tv has started showing a double picture


Hi


Thanks for using FixYa. The issue is with the convergence ICs going bad and needs to be replaced. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs(STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. There are repair kits available which includes repair instructions with the parts, if you want to do it yourself you can buy and repair it yourself. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

Cannot adjust horizontal blue convergence on WS 55857


You still have bad grounds on the ICs. Or maybe the solder has fused another pin. If not bad grounds on the ICs you have missed them elsewhere...Really concentrate and look for these bad grounds and check your caps with a cap check. And power resistors too!!!!!

Toshiba 42" suddenly has blue arc projecting through lower half of screen. Confirmed it was the blue tube by removing the projector lens and looking at the direct image.  Is this a bad tube or something...


Hello,

This is not a bad tube it is a convergence problem. Your convergence amplifiers are malfunctioning, and need to be replaced. If you have a background in electronics, you can remove the back of the TV locate the Convergence ICs (using the schematic or service manual) and the order the parts you will need which are the two convergence ICs and the biasing resistors (you will see these on the schematic). To remove them unsolder the pins, unscrew the screws holding them on the heat sink and remove them carefully, if they stick use a solvent to break down the adhesion of the heat sink paste. Once loose, take them out and then unsolder the biasing resistors and replace them with the ones you ordered along with the ICs.

To install the new ICs put heat sink paste on the back of the ICs and insert the pins into the proper holes in the circuit board. Screw the screws back in securely, and solder the connections back.

After doing this you will need to perform a convergence adjustment, using the cross hair adjustment screen (access this from your TV menu). and the you will need to do an advance adjustment using the crosshatch pattern (also accessed from your TV menu).

Once these are done use you service manual to follow the procedures on locking the adjustments into the TVs memory.

I hope this helps,

Thank you,

Schematic/manual needed for RCA 27V412T Color Television repair


Look for the vertical IC. It should be a small flat IC attached to a heatsink and marked something like LA7837. The IC will have a circuit designation like ICxxx. For example IC301. Check all of the caps in the same circuit (C3xx). One or more are bad &/or intermittant. Start there and keep us posted.

Blue line on TV screen


Hi

Your TV has a vertical fault. Based on your description, chances are that it is the vertical IC that went bad. It is relatively a simple repair job and any person with basic familiarity with electronic components and circuitry and soldering would be able to do the job. Should you venture to do a DIY please be reminded of the standard safe practices involve when working inside a TV unit.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
