I disagree with given info, this tv has no horizontal output transistor because it is dlp tv.
3 red light blink means lamp cover is not placed back properly after lamp replacement/ lamp checking. Make sure lamp cover is fixed back in its place securely and tight.

Check the supply voltage first, if none extract horizontal output transistor might be shorted.
if extracting horizontal output transistor still no B+, power supply dead, check diode, capacitor.
if OK replace the main regulator.
if has supply but low, say 70v time to replace flyback transformer if horizontal out is good.

Hello
Three blinks of standby light to Sony TVs indicates that the regulated voltage output from power regulator board is above thatn normal. The problem is with its power supply regulator board. Replace all the electrolytic cpacitors on that board with new ones. Replace all of them including small and large ones, at one time. OK.

the green is the reboot process and is normal.
the red light is an error code indicator.
count the blinks of the red light...it cant be 30 times (I think)
it will blink a sequence, pause, then do it again for a total of three times.
count carefully, it gives you three chances to catch the number it is blinking.

TV has sound but no picture


It is possible one of the internal fuses blew out.
It could be a bad horizontal outut transistor.
It could be a bad secondary of the power supply went bad
And many other things.
If it's just a fuse, it won't cost much, but a lot of them do not look like you would expect a fuse to look like.It might be a little yellow, green, or gray rectangualar box shaped part. :D
