Sony trinitron 32 in. pip no video, (raster, with audio)

I was given a sony trinitron 32in pip tv, when it's powered up, audio is working, but the video only displays a monochromatic screen with regularly spaced lines (I think, this is called raster?) Is this a shorted picture tube? Or, are these sets prone to cold solder joints?

    It's sort of the solution, I thought it would be. Nice to know I was on the right track. Thanks for the good advice, and fine diagnostics!

What you have described there is a classic example of the jungle IC failure. Ic301 Sony p/n 8-752-101-04. A pic with no color, and lines or grainy texture in the picture. Not a project you want to tackle if you don't have the proper soldering equipment or skills. And not a costly one at a good repair shop.. Only real hurdle is getting that heavy monster into the shop. To answer your question, yes what you described there is raster. Even the salt & pepper looking screen with no real decernable image is described as raster. In fact any image generated on the CRT is raster. And yes, these sets are prone to solder joint problems, usually ring cracking in circuits that generate the most heat.

Sony TV Will not stay on and the light flashes 6 times PLEASE HELP


Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. To get more details, http://electronicshelponline.blogspot.com/ Pull up older posts. Blinking codes to many many models Trinitrons are given.

Hello

Six blinks of standby light in Sony TVs denotes the absence of horizontal oscillation.

No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
In most cases the Ic is foud defective. anyway check its soldering points for any loose contact, or bad solerings. Check the line drive transformer, a very little transformer soldered directly to the main printed circuit board, very close to the horizontal output transistor. Check its primary winidngs for open. If it gets open no horizontal drive signal will be present at the base of the horizontal output transitor, that also may the cause of horizontal stop.

I have a sony trinitron XBR and the PIP won't turn off. Any help is greatly appreciated.


Please make sure that one input is connected to the UHF/VHF port of the TV and other is connected to composite or component ports. If you have connected likewise, please perform the steps below:
  1. Ensure the video source is turned on.
  2. Ensure the video source is connected to an available VIDEO input jack on the back of the television. IMPORTANT: The VIDEO 5 input cannot be used to view a program in the PIP window.
  3. On the television remote control, press the TV FUNCTION button.
  4. On the television remote control, in the PIP section, press the TV/VIDEO button to select the appropriate video input for the PIP window.
  5. If the issue is not resolved, connect the Audio/Video (A/V) cable from the video source to a different VIDEO input jack on the television.
  6. On the television remote control, in the PIP section, press the TV/VIDEO button to select the appropriate video input for the PIP window.
  7. If the issue is not resolved, replace the A/V cable.
