I have sony KP-FR53M96,Red color is little dim and red flashing 5 times,plz could you solve my problem

Seems like your RED CRT is shorting out or failing. Do you notice any other colors besides just red having problems? The blinking of the red light eight times is a High voltage error. It could be your D board but I'm thinking it is more likely the red crt is probably shorting out.

Hi,
I can help you to solve your Sony tv problem.
Is it Sony KP-51HW40 tv or any other model?
How many times red light start blinking after three seconds long pause?
Let me know to proceed, can you check voltages with multimeter in tv circuit board?
Thanks.

the sony type 1 convergence repair kit from www.tvrepairworld.com should solve the issue. The kit contains the parts and the CD with instructions.

Need to replace the lamp. Hope this helps

The adjsutment that you turned down was the G2 voltage to the red tube which is just a temporary fix for a CRT which has a short developing in it. Try turning up the red adjustment again only slightly to see if the red CRT ( tube) will light up
if it does and then the set shuts down its most likely the red CRT which is bad . If it lights up but you get retrace lines but doesnt shut down it possible that its the CR board ( Red CRT Drive Board) which is at the very bottom of the red tube.

this is a common fault adjust the little black box in front behind the small wooden cover. you will see 6 controls don't adjust any of the top 3 only the bottom knobs 1 for each color. slowly back the control counterclockwise turn the set on and wait untill it shows a picture, slowly adjust the control for the color in question utill the color balance is correct- black and white with the color setting turned down all the way with the user menu when balance is ok you are all set.. turn the color back up with user control. rtepeat process if needed.

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

i have a sony tv model kv36fs17. led flashes 5 times. tv works but no red color. would could be the problem? thanks

Replace STK-392-110s or 150s upgrade with 180s replace both ics.

Check the crt card on the picture tube of the red and look for cold solder joints resolder, check the video amp for discoloring of chip, replace.
