The green ones are each tied to a voltage source in the power supply of this set, try to see if one goes off or dim before the others, the red one should always be on.

If one can be seen to go out first or dim first that voltage line is being held down or has a problem.

Its meant to be a way to know which voltages are up and also to narrow down where a problem might be.

SOURCE: Flashin power light - wont come on

The "green light flashing to the chirping" circuit may be defective.

Not a basic diagnosis--service literature and/or knowledge of each green light circuit will be needed.Possible shop repair.

Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Thanks,

SOURCE: I have a 56

I suspect you probably have a bad LED assembly. It could be either the red, green or blue that is bad and give you the same symptom. The problem is locating parts for it as it looks like the light engine is no longer available. I would have a technician look at the TV to verify this and what parts are needed for repair.

My hitachi 1999 tv turns on but off right away has flashing green lights in back


If the flashing green lights are on the circuit board each is tied to a voltage from the power supply----likely damage is there but a 99 may not be economical to fix in 2012.

No picture or sound with a red flashing power light. Have replaced the convergence IC's but no change (do not have the chirpint sound). Removed main power board & green LED does not light up


On that model the conv IC is usually not the solution. I believe its the blown capacitor problem with is an easy fix. Check the site www.TvRepairKits.com for a repair kit.

We have a Hitachi model # 50V720 TV. When you turn it on, green power light flashes, then temp and lamp lights begin to flash, eventually goes to just the lamp. Can you guide us as to what the problem may...


Y sus (sustain) board or main power board has dry capacitors or dead transistors or even main chip is dead, but to know more accurately you need to count the red light flashes. Google "red blinking codes" should find the answer, ebay sells Y sus boards or power boards around $125 (cheapest) for plasma TVs.

Plasma wnt stay on


I have had this problem in some models of plasma sets before. In most cases the power supply and main drive boards had to be replaced. In a small number of cases the failure was the screen itself.

In all cases, the cost of the repair was expensive. For the screen failure, the set was scrapped.

Wont power up


I have seen that symptom many times. Most likely, the little blue capacitor next to the horizontal output transistor has shorted and popped the main B+ fuse. This is very common in those Hitachi projection sets. These parts should be replaced by a tech familiar with Hitachi projection sets.

Anyone know


Usually this occurs when the Convergence ICs go bad along with some chemical fuses mounted on the deflection board. E994 usually blows along with the Horizontal out transistor going bad. This transistor, I believe is Q777 that usually goes bad. The fuses are either tiny little yellow fuse with a red band or green with a yellow band depending on your model number
