Re: won't turn on

What you have there is a V27 Chassis manufatured in 1999..
But it is the same chassis that was later used in their WS55517 65517 and 73517... Regardless of the outcome here are some common caps that ALWAYS need to be replace:
C979 2.2uf 200v
C531 2.2uf 160v
C551 2.2uf 160v
C981 22uf 50v
C402 47uf 35v

Now to your problem, it could be a number of things. The regulator could be suspect, (Ic951 which is a STRF6628) but you might try the following before taking any gunshot approaches. This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB.
Hope this helps!

TV turns on then off no picture

this is very common. it is the power supply going bad. it should run at 130 volts dc. but it is now running much lower that this. just enought for the tv to come on. but not enough to power all the circuits right.

My RCA HDTV D52W23 Will not Turn On!!

Trying installing a new power supply. This is the main problem with tv's with the issue. But if you just bought it I would try to get my money back from where I bought it from. Installing a power supply for a tv is not that hard at all.

Mitsubishi WD-62827---PICTURE TURNS GREEN

I had the same problem. I deducted that if my TV worked fine for an hour or so and then the colors became bad (green, people's faces purple...), it must be a overheating problem. Simple logic, right? So, I picked up a few tools and a small vaccum and went to work.
I went first for the main source of heat: The lamp. Just a few screws, and I removed it. The lamp cage has a fine screen to prevent the dust to cover the lamp. Mine was covered with dust! And the fan behind the lamp was also covered with dust! Bingo!!! That's my problem! I cleaned everything and vaccumed all the air vents on the the back of the TV. I put the lamp back and checked that the fan was working. The TV works like new since!
Before you are out of a TV for days and spend an arm and a leg for a "Technician" to fix it (replacing expensive parts that didn't need to be replaced in the first place), try what I described above first. It's very simple and it takes only 15 minutes.
Since my TV is 2 1/2 years old, I purchased a replacement lamp. I know that one of these days it will burn out. I'll be ready and my TV will be working again in 15 minutes!
Since my problem was solved, I didn't go to the next step. There must be one or two other cooling fans inside the TV, but they must be working...
Good luck,

KP51ws500 turns green and shuts itslelf off

There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.

Mitsubishi WS-65313 - Will not turn on

The most common failure are the two convergence integrated circuits part # 267P173010. The two pico fuses may be open as well, which come from the power supply and provide +24 volts and -24 volts.
