SOURCE: SONY KP-57HW40 TUNS OFF AND STANDBY LIGHT BLINKS 6 TIMES

6 blinks is usually associated with failure of the horizontal deflection amplifier - which shuts down the high voltage system as well.

The repair requires testing to determine the exact parts that have failed. There are, for example, a few hundred parts and a section of the Jungle IC chip involved. So, repairs could require something as simple as replacing some inexpensive passive components OR as complicated as replacing the jungle chip (very expensive).

most of the time it's the horz. transformer and transistor.

SOURCE: Sony Wega stanby light blinks 5 or 6 times

When a Sony TV flashes five times, that means that there is an AKB circuit fault.
Six blinks is also a fault related to video problems, and regards a fault concerning the digital board and the Jungle IC (the main CPU).

This means that there is something wrong with the video.
Try first unplugging power for few hours, if that does not work, call a technician, as several IC and components must be tested and eventually replaced.

SOURCE: Sony KP-51WS500 tv went red screen on me

Off hand I would con dim the Red and Blue CRT"s. If you were to replace two of them I would also do the Green CRT as well. The cost of just doing two of them is way too expensive in my opinion and you would be better served to replace the set instead of investing the amount of money needed in a 6-8 yr. old set.
Hope this helps,

Go into the customer menu and select CONVERGENCE and look to see if red or blue lines are skewed and or will not adjust in some direction.

If this is what you find--you have a convergence circuit problem.

Let me know if this is what you find and I can tell you what parts need to be looked at and replaced and I can give you general instructions about what you will need and the best place to find them.

SOURCE: Sony KP-51WS500 turns red ,shuts off, led blinks 8 times

Here are the fault codes for your tv and what components are affected:

  • 0 times, Diagnosis: Power does not turn on. Possible causes include: Power cord is not plugged in, Fuse is burned out (F6001) (G board). Symptoms of the problem: Power does not come on, No power is supplied to the unit, AC power supply is faulty.
  • 2 times, Diagnosis: B overcurrent (OCP). Possible causes: H. OUT (Q8024) is shorted. (D board), +B PWM (Q8035, 8038) is shorted. (D board) Symptoms of the problem: Power does not come on, Load on power line is shorted.
  • 3 times, Diagnosis: +B overvoltage (OVP). Possible causes: IC501 is faulty (G board), IC5002 is faulty (G board). Symptoms of the problem: TV has entered standby mode.
  • 4 times, Diagnosis: Vertical deflection stopped. Possible causes: +- 15V is not supplied. (D board), IC8003 is faulty. (A board) Symptoms of the problem: TV has entered standby state after horizontal raster, Vertical deflection pulse is stopped, Power line is shorted or power supply is stopped.
  • 5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.
  • 6 times, Diagnosis: LOW B OCP/OVP (Overcurrent/over voltage). Possible causes: +5 line is overloaded. (A, B boards), +5 line is shorted. (A, B boards). Symptoms of the problem: No picture.
  • 7 times, Diagnosis: Horizontal deflection stopped. Possible cause: Q8035, 8038 is shorted. (D board)
  • 8 times, Diagnosis: High voltage error. Possible cause: T8005 is faulty. (D board)
  • 9 times, Diagnosis: Audio error. Possible causes: +- 19V line is shorted. (A, B boards), IC708 is faulty. (A board), PS701 or PS702 is opened. (A board). Symptoms of the problem: No sound

I have seen the tube divider pack cause this too, Take the front speaker grill off remove the 4 screws and the panel comes off. There is a pack with 2 red 2 green and 2 blue adjustments, Try turning the BOTTOM red one down 1/32 a turn and see if the symptoms change

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

Clicking on Blue screen appears then shuts off


The problem sounds to be in the power supply board. May also be a horizontal drive problem. Sorry I can't be of more help, but there are may voltage problems ( shorts, open capacitors, bad chip etc ) that couls cause this problem. The reason the set turns blue when it first comes on is that it doesn't have time ( or can't find a signal and the screen default to blue. Wished I could help more.

Sony not turning on


How many flashes? Is it continuous?

If you count the number of blinks, then go to this site:

http://www.iwaynet.net/~nesda/SonyBlink.html

you will get some idea of the trouble. But, continuous blinking is usually associated with the "jungle" chip which is not a clear and easy cure; it must be further diagnosed by a tech; repairs are probably over $200.

Light blinking...but not coming on


This looks like a problem with the H Voltage or switching power supply section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, and check the voltage output of the switching power supply. What may have happened is a component may have shorted out causing an over-current condition with is triggering the shutdown circuit (These are the relays you are hearing). I would check the Horizontal Output transistor, and the components in that section of the TV.

In addition check the voltage test points on the HV / Horizontal and switching power supply board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.
I hope this helps,
Thank you,
