Yes, It has focus control at side of fly-back transformer. Rotate focus control in both sides to get maximum sharp focus.

Replaced Convergence chips, same problem


This set has pico fuses on convergence board and also on G power board, there should be 2 5 amp pico fuses on power board.

If convergence is bad exactly as before double check the power board fuses and check to see if voltage (it is marked!) is there with power board disconnected from chassis..

No Picture and Lttle red light next to power buttons blinks for about 30 seconds


First thing to do is reset ( see link below) and see if it resets otherwise if problem continues it will need some work

Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. There are some common breakdowns in the High Voltage circuits in this set. One is the flyback transformer. Another is a small high voltage capacitor in the sweep corrction circuit. There is a cap that goes open in a high voltage circuit (C6532) which needs to be replaced.

Have model F25190SE, old 1992 tv, Chassis CTC177AC. No signal coming in from rf connector, television all snowy. Can use the rca connections, still has very fine lines in picture. I've replaced the rf...


cristal and IC to be replaced and solderings on all grounds in the tuner unit. maybe costly for a tv of that age, for the fine lines there are 2 ajustements on the back of the tv set, one is focus and the other one is sceen, that ajustement is too high , just turn the ajustement counterclockwise. the tv will become darker

If you are comfortable with working inside the set where there are potentially dangerous high voltages present, you can probably fix this easily. Open up the back and remove it. Plug the set back in and turn it on. In the lower right hand side will be the flyback transformer (large red wire coming out of the top and going to the side of the picture tube). DO NOT TOUCH IT!!! On the back of the flyback should be 2 "knobs". One will be marked screen and the other focus. Carefully adjust the focus until the picture is clear. When you do this, go beyond the clear point and work the control back and forth a few times before settling in to the focused spot.

That should resolve the problem.

Trinitron color is going out on each side but fine in the center


Hello vineinn2,

I would say that might be the problem, but it might also be a HV problem. I had posted this before and it might help you:

This may be a CRT problem. From what it sounds like i.e. dim picture, colors not bright. If you have a background in electronics I would tell you to check the voltage levels on the CRT pins and compare them to the values on a schematic, however if you do not have a background in electronics, I would suggest you taking the TV to your local TV repair shop and have them troubleshoot your problem.

Here is a possible list of things that might be wrong:

1) CRT going bad (The shop can try CRT rejuvenation if needed)
2) High Voltage on the anode not at proper levels (The shop can check this with a HV probe)
3) Video output levels low (The shop can check the voltage and signal levels on the CRT socket board, and on the video amplifiers.

These are the three primary possible issues.

I hope this helps,

Thank you,

I recently had this same issue. If you remove the speaker pannel in front of the set, you will see a block with 6 knobs on it, just to the right of the center panel. This is called a focus block. 3 knobs on top which control the voltage going to each tube, and 3 on the bottom are for fine tuning focus for each tube.

If your problem is the same as mine, it is a convergence problem. and due to the fact that the picture is turning off, says that one of the tubes is not getting enough power.

NOTE: BE CAREFUL NOT TO TOUCH ANYTHING ELSE BUT THE FOCUS BLOCK, THERE IS EXTREMELY HIGH VOLTAGE WITHIN THE TELEVISION, AND CAN CAUSE SERIOUS INJURY.

1. Make sure the screen is blank, ex video 2 with nothing on. It's easier to tell.
2. very slowly, one at a time turn up the knob on the left top, should control red, untill you start to see lines come on the screen, then turn back just till they dissappear, and you see a black screen again.
3. continue with the second knob on top, just the same as the first.
4. And continue with the 3rd knob on top right just the same.
5. when you're finished, turn off the set, then back on, let is set for a min or 2, then hit the FLASH FOCUS.

If the problem persists, it most likely is a IC chip.

Best of Luck
