It depends on your knowledge and skills to fix this tv problem.
Power light 4 times blink shows problem in vertical deflection section and most probably vertical output chip got defective or not getting proper voltage supply to function correctly.
Check vertical output IC connections on main board and resolder if found dry/ colder solder.
Hope these info will help you to fix tv problem.

I cant get sony trinitron to turn on. the standby/timer red light blinks several times and it wont turn on what can i do i am bored without tv


Likely damage to main power supply-------try to see if there is a specific number of blinks then a pause and repeats like 7 blinks a pause and repeats---that is an error code if there---with it AND THE MODEL NUMBER OF THE TV I might be able or not to help.

Sony Trinitron---Blinks 9 times, won't come on!


A specific model number will probably get you more specific
help.. but if you check around the internet by model number
you will likely be presented with some SERIOUS PART opportunities...

The FASHING LIGHT means you have a hard fault in the power circuits...

The number of flashes is mean to point you to a specific area...

I gave all my big flat screens away in favor of the new
HD stuff... (certainly less reliable than those Sony sers...

Shopjimmy might be a great place to call... but the MODEL NUMBER is a MUST.

Un plug and let stand for one minute. If it still does blink then use the reset on the remote and press it while pressing the power button on the TV.

Standby light blinks and tv won't turn on


Four blinks = No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

Stand by light blinks 6 times, wont power on


Here you find sony blinking codes

SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
function immediately. Check C515 & 516 and the jungle IC, IC206.

SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k
and the unit goes immediately into safety shutdown. Check power supply
regulation and horizontal circuits.
