remove the rear cover, then tried with re soldering cold solder or dry joints at the main board. if can not re solved with re soldering, check with an open resistance or change value resistor at the power supply circuit and at the horizontal section.
Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not re-solder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negative).
Hello Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. Check the power supply section for any loose solderings. Resolder all suspected solder points by applying a little more solder, without making a solder bridge short in between close solder terminals. OK.
Tv is missing a color green,recheck ur tv Ant.hole coaxial cable input.Take the cable apart and reconnect to the Ant.hole again see if this help?Not make a fist with ur hand bang on the tv back cover frame see if the color green come back or flashes?Yes,than the tv CRT video board that is connected to the CRT- picture tube have cold soldering joints around it video board connections sockets,require resoldering the socket joints connections between the CRT video board and CRT tube connections socket.U have tools like a soldering iron,a roll of solders and can do basic soldering work?Yes,this problems just require resoldering that it.
Your problem is caused by dry joints and cold solder on the board. If you have a soldering iron and soldering lead open the back panel of your tv. Look for dry joints around the board especially on the power supply section.Cold solder is hard to spot, it is necessary that your working area have sufficient source of light or you may use a table lamp.
Hope it may help you.
Have a nice day!
Thanks for using Fixya.
May be power supply failure and then maybe cold solder joints...a lot of sanyo's came in the shop that had bad solder joints...we would look for solder joints with a cracked looking ring around them , resolder them, and the set would usually work...you can try to remove the back to gain access to the underside of the board to see if this may be the case...otherwise, it may be a circuit malfunction
On projection TV's there are three tubes red,blue and green. It sounds like the green driver transistor is open. Check for loose connections or cold solder joints on the crt board at the back of the green tube.
No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture.
Sometimes no picture at all. Sometimes picture OK for longer. Sound
Faulty joints on CRT pcb. Cracked solder joints at tube socket
connections on CRT circuit board. Caused variable supply to CRT
heaters. Resolder all socket pins to pcb.
turn the tv off ,disconnect from power source , then you can
wait 1 hour appx. ,for the crt to discharge it self ,or you can
being very carefull discharge the crt by inserting a long
screw driver under the ground strap that runs across the crt
(thats the metallic one ) the other screw driver under the anode
high voltage cap (thats the one that connects to the top center
of the crt) then short the two screw drivers together ,you should
see a little spark if there was any voltage there ,after that you
can solder all the cold solder joints.
May I suggest that you check the main chassis also for cold solder joints.
I have checked many a TV.,and I always check the main chassis to prevent callbacks.
BE SURE NOT TO CREATE SHORTS WHEN YOU SOLDER
USE A 40 WATT SOLDERING PENSIL/IRON
TAKE YOUR TIME. YOU SHOULD HAVE NO PROBLEM.
Check for cold or crystalized solder joints on the board that is connected to the CRT.
I would also check the solder joints around the high power resistors near or around the horizontal section.
