My tv will do one of two things, it will turn on but not show a picture, and the light will be blinking, or will turn off while watching tv, and the light will blink.

Yes, it's quite possible that you indeed may have sufferd from a Power Spike, induced by lightning during the storm, esspecially if plugged in during said storm. I have had quite a few customers ova the years with this exact problem. I always advise my clients to unplug ALL devices during a storm, and for ones that simply cannot be unplugged then some sort of Spike/Surge Protection device MUST be used. As a matter of interest, I have written many a report to insurance companies to support a claim for a replacement.

How's the lamp?? Sounds like a lamp failure which is the most likely problem with these units. The lamp for that unit is Toshiba p/n# 23311083x but a better source would be http://www.dlplampsource.com/ and they have it for $199.00 dollars with free shipping...

No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture. Sometimes no picture at all. Sometimes picture OK for longer. Sound unaffected.
Faulty joints on CRT pcb. Cracked solder joints at tube socket connections on CRT circuit board. Caused variable supply to CRT heaters. Resolder all socket pins to pcb.
