Off topic - a different TV problem

My TV was dropped a very small distance and ever since the picture has
a kind of smearing on certain colours. Also the Standby light now
flashes a special pattern to tell me something is wrong. It was a high
end Sony, about 11 years old. Everything was perfect until it got a
drop a few months ago.

Any idea what the problem is?

Possibly the guns are out of alignment, the mesh is knackered etc.

It's dead. Bin it. At 11 years old, it's not worth the expense.
 
Could be serious or minor...! The LED flashing is an error code of some
description... and this could well be the clue to your problem, this
will flash a number of times usually followed by a space.

Perhaps the drop has damaged the circuit track or tracks on the PCB
upsetting some biassing or signal or other, the microprocessor sensing
this thus the warning signal on the led - this is my guess of what has
happened.

Colour flairing as it is known is usually a sign that the relevant gun
in down in the tube due to age or the biassing on the tube, turning the
contrast control down or altering the screen control or A1 on the tube
sometimes helps.

Thats the trouble with todays tellies, there's all kinds of protection
signals sent back to the controller chip so that if serious enough will
trip the power supply off to prevent further damage.

These cracks are usually either where the pcb is clipped down or around
heavy components, usually around the power supply or line output stages
where there are heavy transformers.

DO REMEMBER-:
Tv sets contain very high voltages that can remain for a considerable
period after the set has been switched off.

*Its the volts that jolt and the mills that kill* a mill is short for
the current in milliamps, ie 0.25 Amps = 250mA.
