SOURCE: Last week I had a

Hi,This is what I know.
Continuous Blinking: Not getting reply from IC301 Jungle IC, Bad "IK" video path, possible short to ground

One Blink: Not used

Two Blinks: B+ over current protect, short in power supply or HV circuit

Three Blinks: B+ over voltage protect: power supply short, check transistors, resistors etc.

Four Blinks: No Vertical Deflection, Check IC1509, Q1505

Five Blinks: AKB Circuit, Check Q705,Q732,Q761, on C board, also check Q218,Q219, Q220 on A board, IK circuit can also cause this try turning screen control up a little

Six Blinks:No Horizontal, No Raster, checkC515 C516, & Jungle IC,IC206

Seven Blinks: High Voltage Shutdown, Flyback, shutdown circuits/components

Eight Blinks: Audio Circuit, IC406, PS401, PS402

These Blink Codes are stored in the set and can be looked up to see what error codes have been stored, To pull up Diagnostic Screen push; Display, Channel, 5, Vol MINUS, then power, a screen should appear with the codes and number of times they have occured. Once the set has been repaired the ERROR CODES have to be removed by the tech, clearing is done by going into the service mode; display,channel,5,volume PLUS, power. Press 8 then Enter everything returns to the factory preset condition.

I will need the model number of the set and also need to know if the led blinks. If so how many blinks does it blink?

SOURCE: my Sony wega tv won't turn on goes into standby red light blinks 10 times then shuts off?

Look at the owner manual as the 10 blinks is a error code or Google the model number to locate that information--Sony error codes are general and often misleading.

I would if looking at the set inspect the lamp first.

SOURCE: Toshiba TV won't turn on

Toshiba? Suspect that if it uses a Lamp for brightness (a model number would help) it may have failed----customer replaceable and if remove look to see it is not shattered inside--2 year, 2000 hour life is normal.

Not making it on or out of standby---first place to look is the power supply for signs of damage or puffed up filter caps there.
