HOW TO FIX CONVERGENCE IC FAULT & HOW MUCH COST APPROX
My TX-47P600H REAR PROJECTION TV on startup i get a few seconds of
sound no picture then a red light just under the screen flashes
intermittently (3 flashes pause etc...) Is it the globe? or some other

Panasonic Flashing codes:
1: ----------------- +140 v.
2: ----------------- Low DC
3: ----------------- Convergence
4: ----------------- HHS
5: ----------------- IC 4011
6: ----------------- IC 4018
3 is convergence, either one of the two convergence ICs faulty, or something else (capacitor etc.) has blown on convergence board.

On my Hitachi there's a convergence button on the front panel. Press that button which will give you red & blue lines. You have to use your remote to converge (align) those lines to correct the picture. If the lines won't converge I've been told it could be a bad convergence IC & tech is needed to fix...could be approx $300 to fix.
The three blinks indicates a convergence IC fault. The convergence ICs must be replaced with the manufacturer replacement part. Use only the original replacement part. Your set uses STK392-110 convergence ICs. These ICs are mounted on a large heat sink. Yes, you can replace it yourself and save few hundred bucks. But you must be knowledgeable enough on how to solder, resolder and use a multimeter. You will need:
Heat sink grease or thermal compound
Small side cutter
Feel free to inform me if you decide to replace the ICs yourself
hi, you`ve lost your convergence ic`s, unless your very proficient at solder work I`d advise you call a tech, will require removing 2 large IC`s and possibly a few small support parts, resistors, chemical fuses etc. Every place is a little different but runs approx. 300.00 at my shop, gl, video-tek
Your tv is having convergence issues, i.e the red, green and blue are not converging properly together to give a suitable picture. you will need to replace the two convergence ics (approx cost $30 a pair), they are rectangular shaped mounted on heat sink and black in color. You will also need to check if the resistors on the output pins of each ic are not open. and finally you will need to re-focus the red and blue using the remote.
This is a convergence problem that is either poor solder connections on the convergence ICs or defective ICs. If you can solder and are comfortable working inside the set where there are ptentially dangerous high voltages present even when unplugged, you can fix this yourself.
Please let me know if you wish to attempt the repair and I'll supply additional details and instructions.
If your red convergence controls will not remove the red in all four directions, you have a faulty convergence IC. You will need to replace both. They cost around ten dollars each. Let me know if you need anything further.
this could be a number of probs.
needs to be ck'd by a tv tech
can usually be repaired for a few hundred bucks
suggestions..audio ic,convergence ic,signal board or power module..note these parts are pricey so trouble shoot to correct part.
