I HAVE A TV TOSHIBA ,MODEL CZ32V61,HAVE NOT DEFLEXION VERTICAL I OPEN AND SEE WHAT F301,R327 IT OPEN ,AND CHANGE THE F301,R27 AND THE IC TA8427K(DEFLEXION VERTICAL),WHEN I CONECT THE TV TO LINE(110 VOLT) THE RED LED IT BLINK AND HAVE NOT DEFLEXION VERTICAL,F301 AND R327 IS GOOD,WHAT HAPPY?

Hi Please check around vertical outpu IC for bad solder joints and you can try to replace the electolitic capacitors in vertical output line. Check if vertical plug (which comes from deflexion coils) is well attached in place.
Hi Please check the DC supply voltage applied to the IC. If it is higher than the specified voltage, replace the filter electrlolitic capacitor near the rectifier diode. This circuit is generally located near the flyback transformer. If this does not work the vertical deflexion coil on the CRT neck is probably defective.
1) you have problem with the Raster 2) the main causes are a) raster b) picture c) sound d) synch 3) since this are not video, the problem is raster. your must test the voltage from section horizontal out +125vdc+vertical output +80v+all other circuit +12vdc 4) test the power supply for defective. see the diagram attached
You haven't vertical deflection.
The ff caused the problem.
1. Dry joints on the vetical section.
2. Blew Vertical ouput IC
3. Open yoke vetical winding.
4. No vertical output from jungle IC.
5. Open supply for vetical ic due to open fusible resistor.
I've suspect that you have #1 and #2 fault. This is not Diy so I've advice you to send to repair shop or look for a qualified tech to isolate the problem.
Chassis for your TV was bult in 1998 and put into mass production in the 1999. It was used in various TVs for over 3 years. So when it comes to decision wether to invest or not, first try to identify the problem and to estimete the repair costs.
I don't have access to the manuals for your specific model, but vertical failures are usually the result of poor connections at the vertical IC or a defective IC. Look for a small flat IC attached to a heat sink with about 9-11 pins. It may be marked LA7837 or something similar. Resolder the pins first. If that doesnot resolve the problem, change the IC.
I think you have a vertical problem. Turn up screen voltage to see if there is a tin horizontal line across screen. If so replace vertical output IC and the 100uf/35v capacitor in the vertical circuit.
This site has the TV manual for the model you listed. On pages 12 and 13 sre the instructions for setting up the channels. Paste the above into the address line of your browser. Highlite it and copy and then paste into your browser.
A white like across the screen means that the vertical circuit has stopped working. Look for a small fuse that looks like a resistor near the vertical output IC, replace that fuse if open and resolder the pins on the vertical output IC.
