SOURCE: Blinking power button

You likely have bad convergence output IC's that have caused one of the supply fuses to blow. This repair will have to be performed by a qualified technician. If you were in our area and has us repair this the total cost of the repair would be about $340 if I am correct about the cause of your problem.

Check all micro-fuses in power supply.If two or three are bad,a convergence circuit O/H will be necessary.Pro help usually required-chassis pull,replace convergence IC's and careful hand- soldering needed to prevent call-back.

My toshiba 42h83 tv has sound but no picture


of course check different inputs etc to make sure something did not get disconnected.

This rear projection set uses 3 picture tubes and the set will protect them if there is a problem in the vertical or horizontal sweep circuits that might burn the screens or the damage the tubes.

No simple answer as a lot of different parts are possible for this problem.

The picture is all waves ,I get sound and color but the picture is all lines and waves,what part should I get??


To fix the shaky picture on the toshiba rear projection tv model number 42h83. You need to either replace the 13 capictors on the hyper module or simply replace the hyper module itself. It's cheaper to replace the caps, but you'll need decent soldering skills to do this. You can replace the entire hyper module with less soldering skills, but I believe the module costs about $100, maybe alittle more. You can find the entire fix by googleing "hyper module". Good luck and I hope this helps

You likely have a bad hyper board.  As time goes on the lenght of time it takes to get a clear picture will increase and eventually the picture will never clear up untill the part is either repaired or replaced.

Toshiba 42H82 RPTV: Sound but no picture


It sounds like the 200v supply to the crt's is missing. this is the source for driving the tubes, other than the high voltage generated by the flyback transformer. If the set got really bright gray with wome white lines that are kinda on a diagonal, this is generally the cause. the source for this voltage is a diode on the secondary of the flyback transformer.

Toshiba 42H83 Hyperboard 20 minute Wavy Line Repair Snafu I have repaired several tvs, this one has been more of a challenge due to lack of only service manual without a schematic. I replaced the caps on the MVPU14 Hyper board. Those that I found bad with ESR meter. I am fairly certain I botched this the first time using surface mount capacitors and possibly shorted something out when I re-installed. The tv came up with a blinkng red power light problem where the tv would not turn on. I removed and re-worked the Hyperboard using thru-hole parts instead, much easier. I still have the blinking red power light with 1 second intervals problem. In trying to isolate the problem I was able to do the following: A) Removed various boards and powered unit up to watch for changes in operation. B) I found out with the DPC Unit (PD0077) removed and all other boards installed, I am able to have the tv respond to the remote and front panel buttons, have sound, but no picture. I was able to hear a DVD player playing in the background that I had connected. C) No Menu can be seen on the screen, the bulbs don't light at all. D) I still haven't ruled out a faulty Hyper board yet as I don't know if its operation is dependent on having the DPC unit (PD0077) installed. I have not found any signs of damaged components, so now wondering what is the next target place to look at. Notes: 1) TV was working fine with nice bright picture before I started repairing the Hyperboard, so I haven't considered convergence issues and such. 2) I have been focusing more on the theory that the first repair of Hyper board had a capacitor shorted possibly up near top of board by LX229. 3) I did check all the pico fuses I could find and none of them appear open. Since I don't have a schematic, if you suggest checking a voltage, please advise part number and pin to check. I was thinking the 5Volt line should be checked, but not sure where. I do notice a 9V signal temporarily upon power up but goes away when power light begins blinking. Thoughts?
