Hi. Switch off (mains switch) the VCR. Then see if you can change channels with your TV remote. Blue screen mostly means that no channel has been programmed. If there is , you should at least have the sound. So, if you have sound, there is an internal problem in the TV. If no sound appears, try to get into setup mode (button Menu)
and programm your channels. I suppose there is signal on your normal areal connection. Check this out with another TV set, or use the tuner from you VRC. I know there are a lot of possibilities, but you can sort this out, step by step. Good luck.
Hello, I have exactly the same problem with the exact same TV, white screen for about 15 minutes and than image appears perfect as if nothing happened. I have asked an ebayer which sells TV parts and he suggested it could be a main board or tcon board. I am quiet hesitant to fix my tv, but if the tcon board would fix it, i'd go for it. Did You manage to solve the problem yet?
you have to turn the screen control up a bit.there are 2 conrols on the flyback transformer,top one is focas bottom one is screen,turn it up 1/8 turn turn set off then on.repeat this until picture appears(if you turn it up too much picture will be to brite with lines and will shut off) if it shuts off just turn contron down a bit then restart it.
OK I got my first TV, first to repair myself that is, and I have no training at all but am kind of a tech dork wannabe. So I checked and I have sound but no signal through the TV tuner, so I hooked up my Zenith VCR to aux 1 and sound with signal appeared, the VCR tuner still works :) so I am leaning toward the TV tuner. It is visibly damaged, and I'm hoping it is as simple as a broken connection. I also noticed a vertical flash and pattern of horizontal lines when it is turned off (white). sooooo I push on.... help!!!!!!!!!!!!! :>}
Sounds as though there is an intermitant, heat-related problem with the HV transformer. You can order this at a tv parts shop or from Sony (probably more expensive) the part number should be on the part or on a schematic. If not, the parts dealer can look it up from the model number.
Could be loss of voltage on secondary or problem on Power supply. Check 4/5 (depnding on chassis) wickman fuses on secondary if none are o/c then replace power supply components with Kit from Loewe. Part number 90415.900.
Should take tv engineer about 1 hour (max) to replace parts form kit.
