On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

7 blinks means High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

A blink of 4 times is an error code that there is no vertical deflection. There may still be a problem with the + or - 15 volt supplies. This error is generate when the vertical deflection pulse is missing. there might be a problem with ic 8003 wich is the vertical drive ic. this chip generates a signal witch is detected by transistor q 8001 check pin 3 to see if you have 4 volt stop signal

The green CRT needs replacement. You can get a replacement CRT from www.tvrepairworld.com

Unfortunately your picture has when out and you need to have the TV serviced

replace the Green CRT. You can get a replacement Green CRT from www.tvrepairworld.com

You need to count the number of flashes before the unit turns itself off. This will give you an error code. Was there any issues with the tv before it happened?

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Hello
Send your email address to me, either by Fixya , or send a mail to me diretly to the belwo mentioned my email. I'll send you the user manual of your TV by return mail. It is an adobe acrobat document, and I cannot send it to you by this site as it allows mw to upload 50Kb only, and the manual has a capacity about 2.8MB. You don't have to pay anything for this. Mention your need also by mail, as I may forget this.OK.

Eight blinks points to an audio output problem. The unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

Hope that helps.

The Blue CRT has developed a short and will need to bge replaced.

There is a failure on the circuitry of your television.The protection mode is activated. It is normally activated when the system detects failure on the circuitry to avoid further damage. The no of blinks show where the fault is.. Say for example: 4 blinks. It shows V stop or 13 volts not supplied.. please do count the number of blinks for us to guide you on how to repair your unit..

If you open up the back of the unit you will see the main circuit board...on the horizontal deflection board is a transformer known as a fly-back...this transformer supplies the high voltage necessary for the tubes to operate...there should be two or three controls on the transformer..usually the top is for overall focus and the bottom for the screen control(in the case of three control...two upper ones are focus)..try tweaking this to see if you can get a clearer pix...if it doesn't help then there may be a problem either with the fly-back, the h deflection, or the convergence circuits that may need to be repaired by a shop

if auto focus won't work then replace the converge stk's and the big resistors connected to the stk's

Hi,
This kind of picture appears due to failure of convergence output section in rear projection tv, please check convergence output chips and replace them (tv has two chips of same number)
Let me know if you have additional question.
Thanks.

IF there is no picture, but have sound the it means the set has no highvoltage. This is confirmed by the fact that the CRTs are not coming on. To find out the exact location of the fault, you are gonna have to tell me how many times the power light blinks in between each pause.

It sounds like the focus pack needs to be replaced (p/n 122392535) and re-adjusted. The re-adjusting could be the tricky part if you haven't done these before.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

User manual says tha the DVI connection is not connectable with a PC. It was intended for portable media players.
