If you are hearing a click and the shut off and on during the time of the set coming to start up, then is possible that the Line output transformer is having a leak and then clearing up later to steady.
Open the back cover and clean up the dirt in the LOT. Now with the back panel taken off - with precaution not to touch any parts- put the set on and listen to any ticking noise.
If so shut off and solder the section from where you re hearing the noise. If the fault still is persistent, the check on the capacitors in the Power, Horizontal vertical and HT.
If you suspect that the set stabilises on heat , use a hair dryer to heat up the circuit in suspicion, then centre on to the component.

You definitely have a bad capacitor and there are bad grounds that need resoldered. You will have to replace the capacitor or two or three. I would certainly look for those in the 200 volt range to 1Mf to 4.7Mfs as most likely to replace. Also you should resolder the vertical IC chip. This is a most common problem here! Thanks for asking!

SONY KV-32xbr50 intermittent


The fault is with some loose contacts. Check and rectify this. There is no more components to replace. Look for any loose solder terminals. That is all. But it will be a difficult task to reach to the exact point of fault.

Green screen and distorted picture sound is good but no picture


It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Screen flickers upon power up


Looks like your picture tube is dying, or there is a bust capacitor(s) inside...I'd recommend taking it to a service shop to get it repaired.

Sony tv picture keeps flashing


You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.
