replace the zero crossover detect diode in the power supply.

It could be either something on the mirror or perhaps the coolant has leked from one or more of the picture tubes. You would have to gain access to the interior of the set to check both of these possibilities.

To be more specific, you will need to find D6116 or D6301 located on the G board, they might be open and will need to be replace.
You can request a service manual from this website.
If you need further assistance, le me know.

Replace focus /screen block.

How much do you know about electronics and can you solder? There is 1 sure way to find out if high voltage splitter is bad disconnected the Flyback transfomer from it /If set comes on and stays on splitter is bad.Make sure you place high votage lead from flyback where it cannot shock you.or short out anything near chassis.Also check little round blue capacitor behind Hori output they go bad 1200pf 2kvolts. This set i think has 2 STK392-??? big black ics if one of them is shorted set will not come on.Its up to you on fix or throw away

They have a guide that goes through the blinking.  I had 9 blinks one time and I had to replace some fuses.  Sorry I don't have a link to the guide

what exact model number of your Sony tv is? I need it to arrange the service manual or schematics.

The 9 blinks on your TV means:
+/- 19V line is shorted
IC708 could be defective
PS701 or PS702 is opened.

To do this repair you will need to have basic electronics knowledge that includes hand soldering, use of a DVM and be very careful when working around high voltage.

How many times Standby LED blinks? Its 3 CRT rear projection TV.

You will need the G board replaced, part number A-1054-157-A. The board is no longer available but you can contact PTS at http://www.ptscorp.com and have them rebuild the board you have in the TV.

This could be the screen amp board or a picture tube shorting.
$$$ yes

This is the fix and it is not likely a do it yourself

Resolder D6116 & D6117 (Surface Mount) REPLACE D6301 (Do not just resolder D6301 REPLACE IT) Can use ECG116 (1N4004) ALL On G Board

try this

This is usualy a problem with a couple of diodes going bad or the regulator. Does the set work sometimes or not at all? I'll try to get you more specifics based upon your model. Figure on $35 or so for parts plus the local labor rate for the total repair cost.

That means current overload transistor Q5001 or Q5201 is shorted on the D board and must be changed

I suggest you sit down for this one! Even a small amount of any liquid on set's internals can reak havoc. What you smelled were components shorting out and possibly burning. Depending on where the water spilled, you may have just one PC board fried, but many circuits are interconnected, which means possible cascade damage to others. Never place plants anything containing liquid on electronic equipment.

You may have inadvertantly pressed this feature on remote. Look for "split screen" on remote or menu, then correct

You may be setting your self up for a major headache. Trying to set convergence requires a professional pattern generator. There are also multiple phase adjustments to prevent linear drift of settings. Please spare yourself, take unit to a professional service!

Consult operations manual to find definition. You might use remote to access menu, then press "display off".

Set has problem in one of the circuits, possibly sweep or video. All modern sets have a diagnostic mode when turned on, such as flashing standby LED. If there is a malfunction, such as a voltage loss or short in one of the circuit boards, the power supply will prevent further damage or fire hazard. Take unit to pro/tech for repair.
