26-11-2006 | | I can assure you that "no video" is not caused by vertical output. So you can pretty much ignore the deal with the SCR--If/when there is a problem with vertical, You'd see a shrunken raster &/or straight line etc.
Bright screen with r |
26-11-2006 | RCA CTC169 | thanks for the Guidance. You are absolutely right the vertical problem is totallt out of question so is SCR.
Yes it is in video. Most probably or tube itself. Because some time blue light is seen sparking at the neck when TV gets warmup. I suspected som |

can you help??i have a Hitachi c28wf560n. 11AK45 doard.
Frame fault .picture fold over at the bottom of screen
Is this likey to be a dry joint, if so where to look??
or
faulty parts?? so what needs to be replaced??
cheers to you.

26-11-2006 | | CTC169, what's the rest. On a CTC169AT2 I'd have you check C4703 (47uf @ 250V). That causes retrace. |
26-11-2006 | | "Because some time blue light is seen sparking at the neck when TV gets warmup"
Aha.. Good old arcing tube. More than likely a heater to cathode short-- while, it is possible to have a problem with a video driver , but it would proly get zapp |
26-11-2006 | | You hear about convergence IC's all the time. RCA uses transistors. I hate RCA! What is the CTC # on the back and I'll see if I or someone else can help. You have a convergence problem it sounds like. |
26-11-2006 | | One of your sensors for auto convergence. |
26-11-2006 | | Vertical fold over is usually dry caps in the vertical area and or a bad verticle ic. Look for an IC with LA78-- . I don't know that exact model. The capacitors around that are the ones that dry out. |
26-11-2006 | | I agree w/vtech. The most common problem is either bad solder conections on the verticle IC or the driver transformer. That black thing you keep taking pictures of runs 25k plus! That means about 25000 volts. It at the least will knock you on your a@@! If |
26-11-2006 | | Chech r216 10k ohm to see if it's burnt. If so you need to replace the resistor and flyback. Most common problem. Don't forget the obvious. Is the horizontal out put transistor good? Q501 pin 12 is your +5vdc, pin 40 is 9vdc, as pin 46. |
