Standby light flashing red w/ no picture, but sound is ok

if you know how to use soldering iron,try to resolder your tv,especially the jungle,regulator and the horizontal section.if not working, check the output transistor a square black plastic w/ 3 legs at the back of the plyback.

My Sony trinitron has the stero lite on steady and standby lite flashes four times then pauses and repeats. Can you tell me the circuit/condition causing the set to not turn on.

sounds like you need a new lamp

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

The power seems ok as it was working fine this morning had kids channel on for my daughter for about 1-2 hours while I was pottering about cleaning then daughter told me TV had gone black

my sony red light flash.but it will not turn on just clicks

When I turn on the TV I hear the click sound and the TV powers up. Immediatly the red (standby) light begins to flash 6 times on and off. this happenes only in the morning, but after 5:00PM when youturn on the TV as if nothing is wrong.

what is the problem?

I own a Sony T.V. model #KV36HS510, Serial # 9024184,Event# E36002407 and it"s aTrinitron brand name. Like the problems before no picture or sound, stand by light on front of unit flashes. When trying to turn it back on you can hear the power click, like it wants to turn on, but does not.

it is a power supply problem it it ok than check horl section

A few weeks ago my set started flashing to a black screen. Now a couple of weeks later, i have no picture, but the set turns on and i have sound. The standby light is flashing. I purchased the set in 2000 so it is seven years old. This is the first problem. Could it be all three of the bulbs? Could it be all three of the bulbs? no as you say that sound is ok that means your power supply &high voltage section is ok. please check chroma ic luminance section or system control section stand by ckt ihanks
