Question about Toshiba MW24FPX 24 in. TV/VCR/DVD Combo
The DVD player was broken when I got this tv. I ordered and replaced the DVD player, now when turned on all I get is a bright lime green screen with horizontal lines through it. I have taken it apart three times and inspected everything that I touched and it all looks good. Any suggestions would be greatly apprciated. Thanks

There are capacitors in the vertical circuit that can cause this problem. You may be able to find these capacitors by using a hair dryer pointed to the suspected bad cap and then when the problem happens you can spry a little cooling spray on it to see if the problem clears up. The vertical output IC could be going bad but this can be checked the same way. if you have no TV solid state repair experience, play it safe and take this set into a local repair depot. Good Luck

Your symptoms suggest that your vertical Ic401 has failed. In your Tv that Ic is a LA78040N-E Toshiba p/n# AE002783. Also it would be wise to test the feeder caps in that circuit, especially anything in the 100uf range.
This is not an expensive repair for a qualified shop. The Ic is under $20.00 dollars and caps are a buck or two - the labor will be your most expensive element of the repair and it shouldn't take an hour start to finish..
Hope this helps!

I have the same problem with my Tv too. There is No phone listing and the number given on the warrant policy is no longer connected. I rang Target and Base is their own brand. If anyone needs it the contact number for Target head office is 1800 814 788.

If the flashing is regardless of source, the CRT could be at fault. H to K short. ( heater to cathode)
