I believe I've answered this one or one identical to it:: If not, No sir... Nothing short... The red blinking timer light indicates the the protect circuit has it shutdown. That's happened because something has probably shorted along the B+ line. If it were here in the shop I would be checking the following: IC911 Str-G6624 regulator PC921 Tlp421 F905 5a Pico Fuse C931 160v/100uf cap and the HOT of course 2Sc2539 One or more of these parts has probably failed but usually not all of them.. So it's not an expensive repair. Now, while you're having that done also have them do the following modifications for greater reliability if it hasn't been done already: Remove D701 you don't need it. Install C705 (47uf/16v) in space provided (near Ic701 Pin 22 ) Replace jumper W122 with ferrite bead (Qqr0582-001z) Add a cap(47uf/16v)between pins 61 and 64 of Ic701 neg to pin 64 and pos to pin 61 This is per a JVC bulletin that the shop you take it to may or may not have. It's a simple and inexpensive modification and will add a measure of reliability to the years this set has left. As a footnote, take the set into the shop yourself and pick it up when it's done. This will help keep the cost down. All-in-all should be less than $150 if all the parts above got replaced. If you have any questions don't hesitate to ask. Hope this helps Bill 360-642-4993

SOURCE: JVC tv "stuck" on sleep timer
I think you would have to turn off the sleep timer mode completely or increase its ON time span, say to 4 hours or so
or the lenth of time you have the TV on for. If that does not fix it then it sounds like a STANDBY MODE fault problem.
Hope this helps.

Hello, I am a tv tech. I worked on a JVC AV-32D502 today. Problem: led flashes / no power or picture at all. Same as trobertson52's set. The microprocessor is bad in my machine. trobertson52, if your sets' relay does not click when the power button is depressed you most likely have the same problem or the standby power circuit is at fault. That circuit supplies +5 volts to the micro.
Edtal you have a different problem with your machine. Your machine is going into shutdown. A number of circuits could cause this and would need to be looked at by a technician to determine exactly which circuit is at fault. High voltage transformer (HOT) \ Vertical Circuit \ Power supply are the most likely causes.
