Question about JVC AV-27720 27" TV

1 Answer

The only thing that happens is the red power light is flashing

The television worked fine until four weeks ago. the screen would go to a straight line horizonally across the screen and we would beat on the side to reinstall the picture. one day it got so bad it finally went blank and silent. the red on/off switch still flashes after it has been turned on and won't quit until it is unplugged. please help.

The Vertical output ic is bad la7832 also has an open resistor in power supply off of pin 7 the ic.
Root cause is probably the zener diode next to the IC itself MTZJ75

TV quits working, screen goes black and red light next to power green light flashes 4 quick flashes . After a second or two of no flashing,red light repeats "code" flash. We pull the power plug at the TV,...


The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.

Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.

basic sony reset below

The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center

Red and green lights blink but why is there nothing on screen?


The voltage from the power adapter is critical for proper operation. If it's a little low, the lights will work, but not the picture. There are capacitors on the motherboard that fail with age, so check them too.
