These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

If the red haze is not convergence---that requires parts.
The set has three picture tubes---with set unplugged and back cover removed clean the three large lens that are topside---as for the red haze a quick way to know what is wrong is with set on turn the color to zero----what color is the screen? Should be black and white--if red to some degree tracking or screen controls may need adjusting inside the set---Yellow picture in that situation is a different issue.
Check High voltage Block.After replacing ic's (STK convergence ic's) you need to adjust Black&White scale.Turn ALL screen adjustments to min.Turn TV on and adjust screen slowly for each gun (I would start with Red first ) when you came to point that you see red background with white lines across, at that point G2 is too high (that will cause TV to shut down,don't worry just lowered adjustment and turn tv back on) so adjust to proper voltage and do the same for each gun.After that, adjust focus for each gun (again all controls are on High Voltage Block and HVB is mounted on front of your tv after you take speaker gril out) black box with 6 controls' screen RGB, focus RGB .
You should do that in dark room in order to get perfect Black&White scale,when all guns are adjusted properly you will see grey picture.Make sure 'Color" adjustment on your display is down to 0. Another step is convergence adjustment ,Flash Focus etc.If TV stil shuts off after all, your Red picture tube is short inside,take crt pcb from tube,make sure TV is unpluged from power before that, and turn Tv on .If stays On tube need replacment...good luck)
Check for about 100 to 500 volts on G2 pin (screen voltage) when screen control is adjusted,if less than 200 volts,remove the g2 capacitor(from G2 to ground) on crt board,if screen regains brightness,then replace capacitor,if ok ,troubleshoot the ABL circuit,look for an open or changed valued resistor,also check your heater voltage.Good luck.Cheers.
Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.
normally when something like this happens, we could right away propose what can be done, in your case, since youve already changed a lot of parts on that tv, you can at anytime fix it. the tv alone is not fixed yet as of the moment but to some it up, experts have already given you some ideas on how to fix the tv. cheers. hope youll fix that tv in no time.
finally a consumer that gives us plenty of info :)
sounds like an overdriven green tube, the only thing you can try is to find the G2/Focus block assembly, either behind front speaker grill or remove back of set and look for a black box approximately 5"X5" , this box will have 6 philips type adjustment screws(plastic) 3 are for focus, do NOT adjust these,
the other 3 are marked "screen" the center screen adjustment screw is for green, turn it VERY slowly counterclockwise while the set is running and pray that your problem dis-appears, be advised that this is a HIGH VOLTAGE device so one hand in your back pocket the other hand turns the screwdriver, if the problem does not go away you have a poor green tube, good luck, sorry I can`t give you the exact location of the G2/Focus block, manufacturers move them to different places every year.
adusting these stuffs needs a special equipment like the color pattern generator. u cannot just adjust this manually. try to inspect the crt circuit board see if there is an open resistor there. u have a luminance problem
In my case, the adjustment was available from outside the TV. Sortof. On the rear of the TVabout 2 inches to the right of the coax in, there are two vertical slits on a little protrusion. Inside the slits are the two adjustment screws. The lower screw adjusts brightness, the upper screw adjusts focus.
I spend 30 minutes popping the case apart just to find that I could not access the adjustment screws from inside. Lo and behold, they made them easily accessible from the outside. On a side note, I have never seen a TV designed as poorly as this on the inside. You have to literally reach in and unplug things just to get the back off. All the electronics save the tube itself are mounted to the rear chassis. On all other TV's I've seen (taken apart, rather), all the electronics are in the FRONT part of the chassis so that they move WITH the tube.
