    How do I adjust the screen controls? It doesn't change anything when I try to do it though the tv menu. Is this done though the 6 adjustment knobs?

SOURCE: Sony Screen keeps Blinking

If the red LED blinks 5 times you have a AKB error. It is caused by the CRTs trying to balance the color, and failing. Its an annoying problem that happens when the CRTs get old. If its just beginning you can balance or slightly turn up the screen voltage to the CRTs to remove the problem, if its in the end stages, the CRTs may need to be replaced. This is however, very expensive. If you are daring and safe around high voltage, pop off the speaker grille, open the front panel up and find the focus block. Don't poke around! those big red wires have 30,000 volts running through them! The focus block is a black square box with six knobs on it. Three are labeled screen, three labeled focus. You will see each row labeled R, G, B for red green and blue. The writing is tiny. Mark all three screen knobs with a colored marker so you know where they started. Then turn each one up slightly. If you have a picture, put it to a black screen or blank input. Turn each knob up just unit you see the color over drive and turn it back down to black. You want to set it just below retrace to maintain black level but drive the CRT fully. Setting this is hard but may fix an AKB issue.

SOURCE: sony kp-53HS10 blinks 5 times then picture goes off, sound ok.

I had the same problem. My TV had been fading for months. When I first turned it on, it would be fuzzy and out of focus, plus the colours would be off, but after it warmed up it looked fine.
Then the other day it started turning off after a few minutes and the standby light would blink 5 times over and over.

I tried following the instruction given in the previous answer, with the following differences;

The front speaker cover did not have any screws at the bottom corners, instead it just popped out.
I just pulled at the sides gently untill it came away.
Next, I had to remove the 4 screw holding the control panel in the center, then pull the control panel out as far as it would come.
Next remove the 4 screws from the 1' x 2' wood cover that was behind the control panel.
This will expose the insides and you can see the 3 tubes and the panel on the right that contains the 6 adjustment pots. The pots were not labled, but I took a guess and got it right.
The ones to adjust are the top 3 (the bottom 3 must be focus)

It took me a while to get it right. be careful not to turn them too far clockwise as when I did it started crackling and I though I had fried something, but I guess I was ok.

I was having trouble getting the right balance, so I turned them all anticlockwise first, then turned each one clockwise till I saw color and then backed them off untill I got a black screen and could see the channel display.

When I finish adjusting them all, I turned the TV off for a few minutes, then back on and left it on for 15 minutes. the blinking did not come back.
I then plugged it back into my satalite reciever and got an awesom picture. Much better then before.

Now when I turn on the TV it has a great picture right away. I'm hoping it will stay this way.

My wife was dissapointed, she was hoping it was toast so we could get a plasma :)

I guess you can't please everyone.

thanks for the help and good luck if you are trying this.

WARNING, there are very high voltages inside the TV, be very carefull not to touch anything.
I used a long insultated screwdriver to adjust the pots.

SOURCE: no picture or sounds red light blinks 10 times

The parts you need are two diodes, D6301, D6309, and D6116, Sony part numbers 6-500-567-21 (D6301 and 09) and 8-719-081-97 (D6116), they are located on the G board, and that's located on the left side of the set, as seen from the back.

D6116 is connected to pin 9 of transformer T6101, and D6301 and 09 are in series off of pin 7 of that transformer.

Is this fixable??

Unfortunately, this sounds familiar. Many of these sony projections had bad crt's.(picture tubes). Now here is a secret I learned along the way. The short in the picture tubes is in the filament, causing that color to overpower all others and sometimes causing pix to disappear until set is shut off and back on. If you are very careful and use an insulated screwdriver, you can sometimes tap on neck of picture tube and knock debris from filament causing extended tube life. This is dangerous and must be performed with set turned on. From front of set gently tap on neck of tube(s) in question using insulated handle of screwdriver to make contact with picture tube neck. Picture will probably flash whichever color tube is contacted. Eventually, if picture stops flashing that color as much, you can sometimes get several more months out of your set without any problems. Only alternative is to try a crt rejuvinator or replace tubes at a cost of 200.00 each if avail. plus labor. Good luck, Russmann.
