    How can something like this happen? I have the same problem with my 37 inch widescreen trinitron, just watched tv 2 hours ago, shut it off. We came back and turned it on, nothing happened just the light blinks a few times and eventually stops. How much should something like this cost to have repaired?

    I have the same problem on a KV-34HS510. I called repair shop to check price but they cant tell what the SMPSU is. Could it be called something else?

Undoutably the SMPSU (Switched Mode Power Supply) is faulty.. This will be a shop job... ensure you get a firm "Quote" and explanation B4 allowing it to be fixed.

Sony Trinitron Wega Standby blinks & the TV won't turn on


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sony KV-32HS420 will not come on has blinking standby light


Get out your original remote and hold the "Setup" button at the same time as holding the On/Off button on the TV set. It just worked for me!! Thank goodness. I was just about to bring it for repair but there's a snowstorm. Here's the link I got this from: http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=http--esupportsonycom-perl-tutorial-displaypltutid297templateid1regionid1KSMFlag7370&sliceId=&docTypeID=DT_TUTORIALS_1_1&dialogID=53101564&stateId=0%200%2053105132

TV won't turn on


The 9 blinks usually mean that the power regulators are shot. This is a relatively simple repair and is a wear and tear item. Expect about $25-$35 in parts plus the local labor rate for the total repair cost. If you want to try and repair it your self, I can look up the part designations and numbers.
Keep me posted.

36 inch sony wega trinitron


I had the same issue earlier this week. 4 year old sony trinitron wega 32 in. I was told by Sony to call technician to repair and have called tech....could be anywhere from $200-$300 repair. I did research the blinks (google "sony blinking codes" to find out what each means) Ours was 6-7 blinks which meant power surge to tv. I advised to Sony that i saw many of the same issues with many of the newer tv's and suggested a recall issue--they denied and where no help.
I will buy a new tv now--definitly not a Sony.

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.

Use a hair dryer on the back right side of unit. Humidity sensor may be causing the unit to stay off. The hair dryer may also remove dust causing a false humidity detection
