Red convergence outline


Hello,

I posted this before, however it fits your situation so here are my suggestions:

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,

Session closed accidently can you get back Shuttle83 or can someone pickup where he left off???


I rarely use a schematic diagram for common tv repairs. If

your tv model fails, many others do,also.That is how we determine which parts to inventory and for how long.Most

repairs on a particular chassis are only difficult the first time---

the next several hundred times are much easier!

That is why Fixya is a good way to get assistance.Provide the

make,model,age and symptoms and we go from there...
