Just picked it up from the side of the road. No surprise it doesn't turn on. I realize it could be a plethora of problems but we want to start with replacing the power system. What parts do we need and how can we get them? Thanks!!
I had problems with same unit turning on and then shutting down full power cut out and then it would sometimes work fine for hours.
Some components soldered in Mex. and some boards soldered in other 3rd world manufacturers, depending on problems, it may be just a bad joint on one pin on a vid board or other board.
Total power shutdown caused by bad solder joints on main power supply transformer, resoldered and it has not missed a beat in 10 years.

Re: Won't Turn On
REQUIRES carefull, meticulous soldering of horiz drive circuit
before replacing four parts or it will blow again...........
Horiz output = 2SC5148 Use OEM or equiv....NO generics...
use 237470 RCA or very expensive SONY or
if it is 2SC4927, use first quality only = measure
Base to emitter LESS than 50 ohms.....
two converter transistors = 2SC4834 generic ok
one .1 ohm resistor R607................
Purchase from TV shop or electronic parts supply........T. know..................

Check this site to get more details about blinking codes to Sony TVs. Pull up older posts there. Count the number of blinks occur at one time switch ON, before you continue. These pre-set number of blinks are fault indications.
At the risk of making you angry, did you verify that 1) it's actually plugged in, and 2) is it plugged into a wall socket operated by a light switch that isn't turned on? (I've actually done the later...Thought I was going to be bald! It was driving me nuts! I KNEW I had done EVERYTHING right, but it wouldn't turn on...Then I realized that I had plugged it into a socket that was also operated by a light switch...yup...turned on the switch...everything after that was LOVELY! Except me...where I kept kicking myself for not catching that sooner!
That's probably not your problem, but I thought I'd mention it...
looks like a( DLP) tv digital light proccessor . aka projection. most likely the bulb is burned out . if so cost is $65-125 bucks. aftermarket bulbs are available online but some dont work or burn out prematurely. if you decide to fix it or buy a new tv ,invest in a surge protector. it will save your tv from problems like this . good luck.
These are the universal remote control codes to Vivo TV. 0004 0005 0009. Check this link to know more codes and proceedings to other brands of remote controls, and buy one remote control that has setup codes with your TV. The above said codes are for GE remote with Vivo TV.
It's probably a write-off. The circuit board inside has been cracked so that some of the copper traces that connect parts have broken. This commonly happens around the area of the horizontal output transformer, which is heavy. The shock of the fall causes the transformer to bounce and breaks the board. Other areas too may have been damaged because of flexing. And worst, the picture tube can be damaged in a fall, so it either doesn't work at all or shows permanently distorted colors.
It's tough to find anyone willing to repair a set that's fallen. Many circuit board tracks are very narrow and hard to repair. Then it's difficult to know if all the damage has been found and repaired, so even if the set starts working a technician doesn't know if something else won't go wrong. And then there's that bad tube possibility; no technician likes to spend lots of time fixing a broken board only to find the set then needs a new tube. Trust me, this has happened to me several times during my career in TV shops.
Your best bet is to use this as an excuse to buy a new LCD or plasma TV. 40-inch models, a good size match for a 32-inch CRT (tube) model, are reasonably priced.
hiii..... If the power supply is supplying the main board with the
correct amount of volts, your controller board or your on off switch
panel is malfunctioning and needs to be replaced. If its the whole
board your looking at a few hundred unless you can find the same tv
with a broken screen and just swap parts.The on/off switch board is
cheaper but you have to remove alot of interior parts to access and
becomes a hastle. thank u rate me!!!
If there is no high voltage and you changed converg. amps, then there are still fuses on converg side that could be bad. Also Horizontal output could be bad. If set is dead or just will not come on and has little sound. These could be 2 different problems.
