If your set was struck by lightening then God Help! you must be lucky.
A first hand look into the set is important to see the extend of the damage and if you see burned boards then it will be bettter to go for a full replacementt of the board.Check cost and decide.
However if you are lucky you can have basic faults in the power section, fuse, surge protector, rectifier, capacitor or the Sm driver.
If fault in the tuner side and there is damage there is no hope.

    If nothing looks burnt, then possible that the microprocesor is damaged if there is power to the circuits and the rail voltage (5v)to the microprocessor is present.
    So do this voltage check to proceed with the check.

Check the fuse inside the TV back cover. Check the power supply
diodes. SMPS circuit. Lightning damage could be anything.

    fuse is normal and other components look health but power disappears before the capacitor

Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.

Sony Trinitron 29inch Color TV


The 2 blinks are an indication of over-current. This is usually because of a shorted component. The most common is the horizontal output transistor. This will be a 3-legged part attached to a heat sink close to the flyback transformer (part with red wire coming out the top). This transistor will be marked C4856 or something similar. Update this with the exact marking and I'll provide you with the full part number and approximate cost.

Sony FD Trinitron WEGA KV-24FS120 24" TV Color changes


Try turning down (off) the color during such an episode. If the image is tinted pink or green instead of black and white when you do this,you have either an intermittent short in your CRT (tube), which is terminal,or a gun drive problem, which may be repairable. If you're feeding it component instead of composite signal,it may just be a bad connection of the B-Y cable.
