    Red light flashing, no picture or sound. Does anyone have a troubleshooting guide for this problem? I understand Toshiba has a service bulletin for this. Does anyone have a copy?

If you haven't already found a solution to this problem, it is more than likely a failed fuse. If you are comfortable with the high-voltage electronics in your TV and are handy with a soldering iron, you can attempt to locate and repair the fuse(s) yourself. However, the fuse is more than likely failing because of an additional problem. It all depends on which fuse failed. Can you get back to me?

My 11 year old Philips 29PT7322 colour tv's screen suddenly went blank and a red light below the screen started flashing. How do I fix the problem


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.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

If blinks continue without any pause, the main board is faulty.
