You most likely have a bad picture tube. Green gun is shorted. Usually a set this size is not economically feasible to put a new tube in. You may also have a green drive problem on the CRT board. Have a shop check it out for you before junking it. Thanks for using fixya.
well I thought they had one there but it looks like they only have other chassis # and I have been looking to try and find your chassis # but the only ones ask for money to get it , but I have found some codes and remedy's for your chassi , you had a 5 blinking code which the diagnosis would be this
5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.
if the blink code is now different then let me know what it is and i'll give you that diagnosis
I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.
HI I have the same problem There are things you can do... For the tuning problem I suspect changing the "RF AGC" will fix that. You need to go into service mode. Turn off TV then hold Vol + and - on front panel and turn on. The TV will come up with extra service menu. Just keep pushing menu till you see "RF AGC" and dont change any values untill you write down what they are or take photo etc. Then just change the "RF AGC" value and see how you go with the tuning. ALL THE BUTTONS ABOVE ARE ON FRONT OF TV. NOT ON REMOTE....Hope this helps....
Phillips LCD TV 17PF8946/37, has no picture at all on the screen, even menu and channel #s not showing in the screen. The screen just have blue color. Everything is working like switch & video. Please let me know what parts need to be replaced and where can I order the parts.
The GE (actually RCA) 25GT516 uses the CTC185 series chassis. The dashes you show look like the old display of a clock that has not been set. I have never heard of this chassis producing those dashes continually on the screen, so the first thing I would do is eliminate any cable box, satellite receiver, DVD or VCR. If you have cable, run it directly to the set and see is the dashes are there. If you are sure that the dashes are being generated within the TV and you have properly set the clock and turned off the OSD, then it soulds like an EPROM problem and the set should be serviced by a qualified tech familiar with the CTC185 chassis.
If you mean thin white lines, this is is an indication of a problem in the Horizontal Drive ckt. most likely the Damper Diode has opened or shorted, this would cause the visual symptom and then the set would shut down, unfortunately this is a problem best left to a qualified technician to repair, hope this helps.
