This may be your lamp fan not spinning. Sometimes you can get it to operate temporarily by cleaning the dust from it & spin the blade by hand to get it started

SOURCE: Flashing red light

Joechillin, how much TV repair experience do you have and do you own a mutimeter as well as an osilliscope? Ok first thing your going to need to do is to get a schemtic diagram. Find out with the scope, if the horizontal drive pulse is there when you turn on the set. If it is not then go back to the SMPS and check that. If it is, check the drive all the way up to the horizontal output transistor. If it is good up to there, and still no sweep power supply? Your going to most likly need to replace the flyback transformer and the horizontal output transistor and go from there. If you are there with this, great. But really man if you have no TV repair experience, we cannot teach you how to, as there are alot of factors involved. There is also alot of High Voltage inside these sets when the plug is even out of the wall. Also everything inside these sets is mounted or soldered on a printed circuit board. This set is a solid state TV and there are NO user replaceable parts inside. My friend, I would Highly recommend that you call in a trained service person to assist you with this repair. Good Luck

SOURCE: sony tv red flashes

LED flashes of 8 times are indicative of a "High Voltage Error" which means something along the lines of "T8005 is faulty. (D board)" according to the service manual. Most likely it will need a professional to look at it. A link to the service manual is here: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

SOURCE: sony kdsr50xrb standby light red 3 times

If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.

NOTE: You may have to replace the lamp also if the issue persists.

15 months into owning our Panasonic TC P46S1 (3 months past warranty), the screen has gone black. The red light on the front flashes 7 times with a pause of 3 sec and then repeats. I have heard horror...


My suggestion is that you get an estimat from a dealer on repair costs and you decide whether you want to spen money on a part or new set. This is a bad circuit board and probably the power supply. The repair will be around $200.00 minimum unless you get lucky and there is no major issues and the board can be repaired.
The service manual says. you have what you call a "shut down circut" it is for safety and when one of the internal boards gets shorted or is not working properly, service doc reads as follows

7 Blinks SOS:
Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times


thiera blinking 7 times is cuase by a fualt in sc,su,sd board.


If the board shorted another before it went dead you could have other issues, thats why you need a tech to look at it and give you an estimate. You never know, this being so close to warranty they might work with you on it.

Just bought panasonic th-42x20k, when turn on hear a clicking sound and then turn off, red light under screen flashing 7 times


Red light flashing indicates that "SC voltage is floating". I'd recommend replacing the SC, SD and SU boards. Also know as the Y sustain (SC), Upper and lower buffer boards (SD, SU).
I suggest you contact your local Panasonic Service Agent as parts are only available from Panasonic and are quite expensive.
