SOURCE: When trying to power on it blinks 9times then

Hello: ( 9 blinks on this model indicates an audio problem. Three times indicates you may need service to replace IC501, and IC5002 on the G-Board. It may be better and cheaper for you to just have the G-Board replaced as to replacing individual componets. This is an over-voltage detection issue, and will need to be serviced by an service technician.

Panasonic tc-p50ut50 light flashes 9times wont turn on


These 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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

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.

My sansui hdlcd1909 19 in. lcd tv won't turn on. the standby red light blinks once, what can i do to turn it on?


sounds like bad capacitors on the power board. Very common problem. I would look at the caps if any appear even slightly rounded on top they are bad. They should be perfectly flat on top any puffing up means replace that cap.

Sony tv won't turn on, light in standby blink three times


that is a master control board failiure, it is caused by having your TV on all the time, when the TV gets warm, you need to shut it off and let it cool down(that caused your problem) call sony and order a replacement part, it will take you about 20-40 minutes to install yourself.
